ADVANCED TRAVELER INFORMATION SYSTEMS FOR COMMERCIAL VEHICLE OPERATIONS

Advanced Traveler Information Systems are being studied by the Federal Highway Administration in the hope of making private and commercial driving safer and more efficient. In many parts of the country, existing roads are overloaded with traffic, and in the most congested places, there is no land available for building new roads. The purpose of this study is to examine some of the ways that drivers might be helped to make better decisions on the road. For instance, we all have routes that we normally use because they are quicker and easier than other routes. Sometimes, though, there are traffic jams that we would just as soon go around. The kinds of systems that we will ask you to evaluate today would tell you about traffic tie–ups along your usual route and let you plan ways to avoid being caught in traffic.

At this point in time, the traveler information systems are expected to include many features, such as, navigation aids, warning and safety systems, administration aids, trip planning, and vehicle monitoring systems. Private vehicles and commercial vehicles may have different versions of these basic features. In addition, commercial vehicles will have features specific to the transportation industry, such as a monitoring system for the trailer, and a system that automatically registers for trip permits as you drive by. To provide these kinds of features, vehicles will be equipped with sensors, computers, and displays that will present information about your vehicle, the road and your route. For example, a dashboard display could be used to show maps or long text messages. A voice system might be available to read messages to you and to take voice commands from you. A computer system could be used to maintain large amounts of information and to help you get at it when you need it.

While you are here today, you will help us evaluate some of the different features that may become part of an advanced system. Some small parts of the advanced systems are available now, such as refrigeration monitors and weigh– in–motion systems. These are just small pieces of what you may eventually have in the cab, and the current versions of the systems will certainly change as they are incorporated into larger systems. As you complete the evaluations, you will be voicing your opinions about the kinds of systems that will help you in your work. We would like you to use your experience as commercial drivers to help us decide which of these features would be valuable to you in doing your job.

You will notice that there is no place for you to write your name on any of the evaluation forms that we are using. None of your answers or comments can be traced back to you, so none of your opinions can be passed on to your employer or to anyone else. The only form in which your answers will be made public is in research reports in which no one is identified by name as a participant, and any results are usually group averages and not individual responses. The research reports may include some of the comments that you choose to make, but your name will never be associated with them. There is only an ID number on all of the pages of this booklet. This lets us maintain confidentiality while keeping all of your evaluations together.

COMMERICAL VEHICLE FEATURE DESCRIPTIONS

Before you can evaluate the features of an advanced traveler information system, we need to give you some definitions of what the features are. The advanced system features described below include examples to help you understand how each feature works and how you might benefit from it. However, these are only examples, if you can think of other ways that a feature would be helpful to you, please make a note of them. After you read the definitions, we will discuss them, and your notes will be helpful. The features are in alphabetical order.

BROADCAST SERVICES This feature gives you information about the services offered by local businesses. For example, if you were driving on an interstate highway, it would tell you where you could get food at the next exit, what time the restaurants open, and what kind of food they serve. This is similar to the billboards you see next to the highway or advertisements that you hear on the radio. The difference between this feature and the billboards or radio ads is that you can choose what kinds of information you want to see and what you don't want to see. For example, you could tell the system to tell you about service stations that sell diesel fuel and not stations that only sell gasoline.

CARGO TRANSFER SCHEDULING The cargo transfer scheduling feature gives you information about airplane, ship, train, and tractor trailer schedules that must be coordinated with your delivery or pick–up. For example, if you need to deliver cargo to a ship, the system would keep you posted on when the ship would arrive and when you could unload. If you need to pick up a load from a train arriving from another city, you would know when the train would arrive, where you should pick up your load, and when it would be ready. This information would be updated frequently so that you would know if there were any last minute changes in arrival, departure, or shipping information. This feature could be used while you are driving.

DISPATCH CONTROL This feature will help the dispatcher in locating vehicles, scheduling pick–up and delivery routes, communicating with drivers or customers, and transferring loads between carriers (e.g., from truck to airplane). This feature is similar to other features like route scheduling, vehicle location update, voice and message communications, and cargo transfer scheduling, but the dispatcher, not the driver, would use the system.

EMERGENCY AID REQUEST This feature sends a "mayday" signal to police, ambulances, fire trucks, and tow trucks. The signal would act like a beacon that would let emergency vehicles track you down. It would automatically send the signal in situations in which you may not be able to request help by yourself. For example, the system would send this signal if your vehicle rolled over. In other situations, you could use the system to request aid for others or yourself.

FLEET RESOURCE MANAGEMENT This feature shares information among dispatchers, drivers, and management. For example, the system might transmit information about the vehicle so that maintenance can be scheduled for trucks that need repair. Trip recorder data could be automatically sent to the payroll department to determine the amount of your next performance bonus. Driver information could also be transmitted to help schedule your next rest interval and your next run.

IMMEDIATE HAZARD WARNING This feature will tell you about temporary roadway hazards that are very close to your truck. This includes unsafe road conditions (ice, oil, gravel, sunken grades, etc), approaching emergency vehicles, stopped school buses, and accidents on the road. These are localized warnings that would serve the same purpose as flares and flashing yellow caution lights. For example, you might get a warning about stopped school buses when you are 1/4 mile from the bus. Emergency vehicles may transmit warnings up to 1/2 mile and give you the direction from which they are approaching. The advantage with this feature is that you would not have to see the hazard or hear a siren. The warning would be available at larger distances.

IN–VEHICLE ROADWAY CONTROL SIGNS The system will give you all types of current traffic control signs in the cab instead of at the side of the road. For example, you could get street names, interstate numbers, mile posts, and exit signs. You would get warnings about sharp curves, steep grades, merging traffic, and dead ends. Speed limits, stop signs, yield signs, and one–way street signs would be included, as would low clearance, bridge weight limits, narrow roads and bridges, and truck route signs. You could tell the system what information you want and how you want it presented. For example, you could tell the system to show you interstate mile markers every 20 miles. On the other hand, you could have the system give you both a voice warning and a visual message for critical information like low clearances that are less than one foot above your trailer height.

REGULATORY ADMINISTRATION This feature will keep records for regulatory requirements such as licenses, taxes, and permits, for the driver, the vehicle, or the cargo. It would also fill out and update the trucker's log book and trip sheet. This feature would have an electronic ID that operates while the truck is in motion. This would allow automatic toll collection, automatic payment of fees, and automatic registration for trip permits, all without stopping.

ROAD CONDITION INFORMATION This feature will provide information about on–going roadway hazards in an area that you select. For example, you could get information about bad weather, traffic jams, road construction projects, and road closures. Road condition could be reported for your current location, or you may request information about the next several hundred miles along your route.

ROUTE NAVIGATION This feature will probably include an electronic map that shows you the area in which you are driving. You can see a large area of the map with very little detail or smaller areas of the map with more detail. For example, the large area view would show only the interstates, primary, and major secondary roads. The view of a smaller area would show all of the roads in that area, business parks, airports, etc.

ROUTE SCHEDULING This feature will schedule multi–stop routes without the help of your dispatcher. You tell the system what pick–ups and what deliveries you have to make and it shows you the best route. The route would be designed to minimize your driving time, meet the delivery deadlines of your customers, and arrange the loading of your truck so that unloading is easier. If your delivery schedule changes while you are on the route, you can enter the new delivery information into the system and it will show you a new route. The truck must be parked before you can use this feature.

ROUTE SELECTION AND ROUTE GUIDANCE Once you enter your current location and your destination, this feature will show you several choices from which you select the best route. You can choose the quickest, the most scenic, the one with the fewest tolls, fewest stop lights, most interstates, etc, based on what is most important to you. Restrictions, such as weight, height, cargo, and truck routes, would be used to create the route choices. All of the information can reflect your current location, or you could use the system to plan a long–haul route. For example, if I–80 was closed at the Mississippi River, you might have the system plan the shortest detour from I–80 to I–70 and back.

Once a route is selected, the system could provide detailed directions to your destination. The directions for the detour from I–80 to I–70 could be as simple as I–55 South out of Chicago to I–70 through St. Louis to I–35 in Kansas City, then North to I–80 at Des Moines. Directions for city streets can be more detailed, for instance, by providing a warning one block before an upcoming turn. This level of guidance would allow you to change lanes to get ready for a tight turn.

The system could also show you an alternative route to your destination if conditions change after you have started driving. For example, if you select a route to a warehouse, and then, you hear on the radio that traffic is slow on that route, the system could re–route you from your current location. You would enter your current location and the location of the traffic jam and the system will show you a new route. As another example, your dispatcher might tell you to deliver a package in one part of town and then change his mind after you leave. In this case, you would enter your current location and the location of the new delivery, and the system will show you a new route. For complex re–routing, you may need to pull over to enter new information and select a new route.

SERVICES DIRECTORY This feature is similar to your local yellow pages. It contains the names, addresses, and telephone numbers of most of the businesses in an area. You can choose which directory listings you want to see. For example, you could ask for listings of public scales in the area. Or, you could request towing companies that are located in the last town you passed. You could even limit the search to those that will bill your company for towing instead of asking for cash on the spot.

VEHICLE/CARGO CONDITION MONITORING This feature will monitor the status of your vehicle and tell you about any potential or existing problems. This system would also be able to analyze problems with your truck and identify the cause of the problems. For example, this system could automatically perform the pre–trip inspection. Over longer time periods, the system would monitor air pressure, for instance, and alert you to a slow decrease in pressure that might indicate a failing brake system component. Cargo monitoring would include, for instance, temperature, humidity, vibration, and load balance. This feature would check your vehicle and cargo before driving and monitor continuously during a trip.

VEHICLE LOCATION UPDATE This feature will show you your location in what ever way makes the most sense to you. If you have an electronic map, the system could point to your location on the map. If you do not have a map, the system could tell you the name of the street you are on and the next cross street, or give you the closest highway milepost.

VOICE AND MESSAGE COMMUNICATION This feature allows 2–way voice communication. For example, a paramedic could call the hospital from the ambulance and tell them about the status of an accident victim. A long–haul trucker could call a dock manager to find out where to unload. With the message feature, if no one is there to answer, a message could be sent similar to the way that telegrams are currently used by some drivers. This feature could also include some "profile" information. For instance, some customers don't want to receive calls from a driver. They want to deal directly with the dispatcher. For this type of customer profile, your attempt to contact the customer would be re–directed to your dispatcher.

This feature allows 2–way or 1–way communication with your destination, your dispatcher, other drivers, repair stations, or your home. While you may now use cellular telephones and CB radios, you must be able to get in touch with someone before you can talk to them. With this feature you can send or receive messages without being in your truck. In other words, it has an answering machine that will take your messages and a timer that lets you send messages when you aren't there. Other drivers and your dispatcher could leave you messages that you would see when you returned to your truck. The system also allows you to send the same message to several people at the same time. For example, if you wanted to tell five other drivers about a bridge closure, you could send one message rather than five.

INSTRUCTIONS FOR FEATURE EVALUATION – – PART ONE

You have read the descriptions of the features on pages 2–5. These are brief descriptions of some of the things that may be incorporated into advanced traveler information systems. For each feature, we would like you to estimate its value to you in performing your job as a commercial vehicle operator.

We have assigned a value of 100 to the feature VEHICLE LOCATION UPDATE. For all of the other features, we would like you to estimate the value of that feature using any number greater than 0. Re–read the description for VEHICLE LOCATION UPDATE on Page 5, and then re–read the description for BROADCAST SERVICES, the first feature in the list on the next page. If you think that BROADCAST SERVICES are more valuable than VEHICLE LOCATION UPDATE then write a number greater than 100 in the blank next to BROADCAST SERVICES. If you think that BROADCAST SERVICES are less valuable than VEHICLE LOCATION UPDATE, then write in a number less than 100.

Once you estimate the value of the feature, write the number in the space to the left of the feature name. For example, if you thought that the IN–VEHICLE ROAD CONTROL SIGN feature was only 75% as valuable as VEHICLE LOCATION UPDATE, you would write 75 in the space provided. On the other hand, if you think that IN–VEHICLE SIGNS are twice as valuable as VEHICLE LOCATION UPDATE, write 200 in the space.

Work your way down the list of features on the next page, re–read any of the descriptions that you want to, and write an estimate for the feature in the blank space. The list on the next page is in the same order as the descriptions. Remember, you are estimating the value of the feature in performing your job. Take as much time as you need, and change your mind if you think of something new that is important.

Example

Value of Feature Feature Label
100 Vehicle location update
200 75 In–vehicle roadway control signs

Please provide only one value for each feature. Write your numbers clearly. If you change your mind, be sure to mark out the old number.

You may refer back to the descriptions on pages 2–5 when estimating the value of any of the features. If you have any questions about the procedure or the features please ask one of us.

INSTRUCTIONS FOR FEATURE EVALUATION – – PART TWO

We would like you to do the same kind of evaluation once more, only this time, we have assigned a value of 100 to the feature VEHICLE/CARGO CONDITION MONITORING. Everything else is the same.

We still want you to estimate the value of each feature in performing your job. The difference is that you now compare each feature to VEHICLE/CARGO CONDITION MONITORING instead of VEHICLE LOCATION UPDATE. Estimate the value of a feature using any number greater than 0. If you think that the feature is more valuable than VEHICLE/CARGO CONDITION MONITORING then the number should be greater than 100. If you think that the feature is less valuable than VEHICLE/CARGO CONDITION MONITORING then the number should be less than 100. Once you estimate the value of the feature, write the number in the blank space to the left of the feature name.

Please provide only one value for each feature. Write your numbers clearly. If you change your mind, be sure to mark out the old number.

You may refer back to the descriptions on pages 2–5 when estimating the value of any of the features. Again, if you have any questions about the procedure or the features please ask one of us.

Estimated Job Value Feature Label
______ Broadcast services
______ Cargo transfer scheduling
______ Dispatch control
______ Emergency aid request
______ Fleet resource management
______ Immediate hazard warning
______ In-vehicle roadway control signs
______ Regulatory administration
______ Road condition information
______ Route navigation
______ Route scheduling
______ Route selection and route guidance
______ Services directory
_100_ Vehicle/cargo condition monitoring
______ Vehicle location update
______ Voice and message communication

FEATURE COMBINATIONS AND OPTION PACKAGES

When the individual features are combined into option packages, additional capabilities become available. For example, if an option package includes VEHICLE LOCATION UPDATE and EMERGENCY AID REQUEST, the mayday call would automatically give your location (Nebraska Interstate 80 – milepost 253). Without the VEHICLE LOCATION UPDATE, the mayday signal would act as a homing beacon, and emergency services would have to track you down. On the next few pages, we will describe several option packages that might be made available. Some of the additional capabilities will be described. If you think of any that we have not described, please make a note of them. Again, we will discuss the option packages, and your notes may be helpful.

DRIVER SAFETY OPTION PACKAGE

EMERGENCY AID REQUEST
IMMEDIATE HAZARD WARNING
IN–VEHICLE ROADWAY CONTROL SIGNS
ROAD CONDITION INFORMATION
VEHICLE/CARGO CONDITION MONITORING
VEHICLE LOCATION UPDATE
VOICE AND MESSAGE COMMUNICATION

This package of features is aimed at the safety needs of the driver in a variety of situations. In case of a serious accident involving your vehicle, the EMERGENCY AID REQUEST feature would automatically alert emergency services, and since VEHICLE LOCATION UPDATE is included, your current location would be sent as part of the alert. In less threatening situations, other features are intended to help you avoid problems. For example, other vehicles equipped with the emergency aid feature would also provide IMMEDIATE HAZARD WARNINGS about an accident that just happened. You would also be notified about other hazards, such as emergency vehicles approaching from behind you and a patch of gravel road around the next curve.

In–cab display of ROAD SIGNS would make sure that you don't miss important information because a road–side sign is missing. ROAD CONDITION INFORMATION would let you know well in advance of any adverse weather or traffic conditions. You could find out that chains are required on I–5 north of Redding. Since you have the vehicle location feature, you could ask the system for a reminder when you are within 10 miles of an area where chains are required, if they are still required when you get that far.

VEHICLE/CARGO MONITORING would keep you up to date on the condition of your vehicle, and alert you if anyone had tampered with it while you were out of the cab. Also, the monitoring system could send messages to your dispatcher about problems that need to be fixed. VOICE AND MESSAGE COMMUNICATION would allow you to keep in touch with your dispatcher and with other drivers, and it would allow you to call for any type of assistance that you might need.

DRIVER SERVICES OPTION PACKAGE

BROADCAST SERVICES
ROUTE NAVIGATION
ROUTE SELECTION AND GUIDANCE
SERVICES DIRECTORY
VEHICLE LOCATION UPDATE
VOICE AND MESSAGE COMMUNICATION

This option package combines information about enroute services with the navigation and communication systems. BROADCAST SERVICES includes information that is transmitted over a short range to tell you about roadside services available at the next interchange, for instance. This would include perhaps all restaurants, service stations, and lodging, with their hours of operation and prices. You could set up the system to tell you about only those things that are important to you, like diesel fuel prices. The SERVICES DIRECTORY feature gives you an in–vehicle yellow pages that you could use to find special services that may not be included in the broadcast services. The location of public scales could be found in the services directory. With the VEHICLE LOCATION UPDATE feature included, the services directory search could be restricted to cover, say, 5–10 miles around your current location. Since this package also includes the ROUTE NAVIGATION and ROUTE SELECTION AND GUIDANCE features, the location of a selected service could be shown on your electronic map with the closest one highlighted, and a route to it selected. Using the VOICE AND MESSAGE COMMUNICATION feature, you could pick the phone number out of the services directory and call to be sure it is open before you drive there.

MANAGEMENT OPTION PACKAGE

DISPATCH CONTROL
FLEET RESOURCE MANAGEMENT
REGULATORY ADMINISTRATION
VEHICLE/CARGO CONDITION MONITORING
VEHICLE LOCATION UPDATE
VOICE AND MESSAGE COMMUNICATION

The main benefits of this package lie in fleet management. The DISPATCH CONTROL and FLEET RESOURCE MANAGEMENT features would allow your company to keep track of your load and better coordinate with customer delivery requirements. The REGULATORY ADMINISTRATION feature would help the company keep track of permits, licenses, and fees and it would help you, the driver, by eliminating the need to stop at weigh stations, to pay tolls, and to get trip permits. VEHICLE/CARGO CONDITION MONITORING would provide information to you and to your dispatcher about the condition of your vehicle (oil pressure, air pressure, engine temp, etc.) and your cargo (load shifts, temperature, vibration, etc). Either you or your dispatcher could take any actions that might be needed to keep the vehicle in good running condition. In this package, VEHICLE LOCATION UPDATE would let your dispatcher know where you are. The VOICE AND MESSAGE COMMUNICATION feature would keep you in contact with your dispatcher and allow for transmission of regulatory information and of vehicle monitoring information.

NAVIGATION OPTION PACKAGE

CARGO TRANSFER SCHEDULING
ROAD CONDITION INFORMATION
ROUTE NAVIGATION
ROUTE SCHEDULING
ROUTE SELECTION AND ROUTE GUIDANCE
VEHICLE LOCATION UPDATE
VOICE AND MESSAGE COMMUNICATION

The navigation package provides a full range of services for route planning, route following, and drive–time handling of detours. The core of the option package is the ROUTE NAVIGATION feature. This feature has an electronic map which would show streets, secondary roads, freeways, interstates, towns and cities, and state boundaries. What you would see on the map depends on the scale you select and on the area you choose. The map could show Northern California or a street map of Santa Clara.

If you have a delivery to make on Lawrence Expressway in Santa Clara, you could mark the location of your delivery, and the ROUTE SELECTION feature would identify route options for you from your current location. Using roadway restrictions and ROAD CONDITION INFORMATION about construction, weather, traffic congestion, and accidents, the system would show you suggested routes, along with estimated travel time. After you select your preferred route and begin driving, the ROUTE GUIDANCE feature would alert you to upcoming exits and turns so you would have time to get into the proper lane. Also, if any new road condition information comes in, the system would suggest ways to get around any problems. For instance, the system might suggest diverting to the Central Expressway to avoid an accident on 101. Since the VEHICLE LOCATION UPDATE feature is included in the package, the system knows your current location, and a change in route could be automatically selected.

As you drive, the system would monitor your progress, monitor road conditions, monitor incoming messages, and coordinate with your ROUTE SCHEDULE. While enroute, the system could receive a message from your destination stating that all loading docks are occupied and that you would have at least a one–hour wait before unloading. You could then ask the system to identify any other delivery that you could make during the next hour, select your route to the new destination, and send a message to the next delivery point saying that you will arrive earlier than planned. After making the re–scheduled delivery, the system might alert you that you probably don't have enough time to make your next delivery and still meet the schedule for a transfer to an air cargo service. The system would again re–plan your deliveries to go from your current location to the drop point for the air freight, and then on to the next delivery point.

OPTION PACKAGE EVALUATION

We would like you to evaluate the option packages that were just described by comparing them to a package that contains all of the features, the COMPLETE FEATURE PACKAGE. As in the earlier evaluations, the complete feature package has been given a value of 100. For each of the other packages, assign a number that reflects the value of that package compared to the complete set of features. If you judge the package to be of less help than the full set of features, give it a number less than 100. If a package is more helpful to you than the full set, give it a number larger than 100.

INSTRUCTIONS FOR FEATURE PAIR COMPARISON

On the next 10 pages, there are pairs of features shown inside of boxes. We want you to compare the two features and tell us which feature in the pair would help you the most in doing your job. Then tell us how much less of a help the other feature is. For example, for the pair

FLEET RESOURCE MANAGEMENT _______ <– –> _______ IMMEDIATE HAZARD WARNING

you would decide which of the two is most helpful, and write a 100 in the blank closest to that feature name, for example,

FLEET RESOURCE MANAGEMENT _100___ <– –> _______ IMMEDIATE HAZARD WARNING

This indicates that FLEET RESOURCE MANAGEMENT is more help to you in doing your job than IMMEDIATE HAZARD WARNING. Next, you would write another number in the other blank, a number between 1 and 99 to indicate how helpful the second feature is compared to the first. If HAZARD WARNINGS are only half as helpful as FLEET RESOURCE MANAGEMENT, write 50 in the blank.

FLEET RESOURCE MANAGEMENT _100___ <– –> __50___ IMMEDIATE HAZARD WARNING

If the two features are just about equal in helpfulness (both very helpful, both not very helpful, or just equally helpful) put a 99 in the other blank.

YOU MUST PICK ONE OF THE TWO AND GIVE IT A 100. THEN, YOU MUST GIVE THE OTHER ONE A NUMBER BETWEEN 1 AND 99. Please do not skip any. Each of the feature pairs is different, there are no repeats.

At the end of each page, please stop and check to be sure that you completed all of the feature pairs on that page.
