Contract Research Studies

1. Hazard Index for Assessing Pedestrian and Bicyclist Safety at Intersection

Introduction and Background:
The need for research to develop new tools to mitigate the loss from pedestrian- and bicycle-motor vehicle crashes is well founded. The annual number of fatalities in the U.S. resulting from these collisions between motor vehicles and pedestrians and bicyclists has been around 7,500 for some time, accounting for approximately 15 percent of all traffic fatalities in the U.S. (NHTSA, 1998). Many more injuries are not reported to record-keeping authorities. A study by Stutts, et al. (1990) showed that fewer than two-thirds of bicycle-motor vehicle crashes serious enough to require emergency room treatment were reported on State motor vehicle files. Recent HSRC research for FHWA presented in Accident Analysis and Prevention corroborates such findings for both bicyclists and pedestrians (Stutts and Hunter, 1999).

Around 40 percent of pedestrian collisions occur at intersections, and an additional 8 percent at driveway or alley intersections (Hunter, Stutts, Pein, and Cox, 1996), and a variety of factors play a role, including pedestrian age, width of the crossing, street corners with large turning radii permitting higher motor vehicle speeds, and misunderstanding of pedestrian signals (Zegeer, 1991). Hunter, Stutts, Pein, and Cox (1996) also found that intersections are present in half of bicycle-motor vehicle collisions. Related factors include age of bicyclist, motor vehicle speeds and traffic volumes, provision of auxiliary right turn lanes, and other designs which lead to weaving between bicycles and motor vehicles.

Objectives:
The main objective of this research is to develop hazard indices that will allow planners, engineers, and other practitioners to easily identify features, or combinations of features, at intersections that place pedestrians and bicyclists at risk. By then developing user-friendly guides to get the information in the hands of practitioners, the indices can be used to identify hazardous locations. Specific countermeasures can then be implemented to reduce certain types of hazards. Intersection indices should also be helpful in influencing future intersection design, as well as accommodating the needs of pedestrians with disabilities.

2. Evaluation of Safety, Design & Operation of Shared Used Paths

Introduction:
Shared use paths, as defined by the 1999 American Association of State Highway and Transportation Officials Guide for the Development of Bicycle Facilities (AASHTO Bike Guide), are "facilities on exclusive right-of-way and with minimal cross flow by motor vehicles" (1). Shared use paths also are sometimes referred to as bicycle paths or multi-use trails. They are most commonly designed for two-way travel and, even when not, will be used for two-way travel unless precautions are taken. Shared use paths are used for both utilitarian and recreational purposes. These facilities' users include various types of bicyclists, skaters, and pedestrians and have become increasingly popular among these groups. The resulting mix and increase in volume of nonmotorized traffic can lead to conflicts, creating congested and dangerous conditions for all users.

Objectives:

3. Identification of Alternative Methodologies for Collecting Pedestrian Exposure & Crash Data

Justification:
The need for timely and useful data on pedestrian exposure was identified as a high priority at the Joint NHTSA/FHWA Pedestrian and Bicycle Safety Strategic Planning Workshop held in April 2000. The objective of this study will be to identify the best methods for collecting and analyzing both pedestrian exposure and crash data. Currently, very limited information is available on where, when, and how much people walk. Without this type of information it is difficult to determine the relative risks associated with various pedestrian activities, subsequently take steps to improve pedestrian safety, and measure the effects for these improvements. This endeavor will also support the efforts of the DOT Pedestrian and Bicycle Team to coordinate its activities.

Objectives:

4. Characteristic of Emerging Road and Trail Users

Introduction:
There are a number of newer or emerging users of our nation's roadways and trails who may have characteristics that affect the design requirements and safety performance of these facilities. These include persons using in-line skates, scooters, strollers, electric bicycles, adult tricycles, recumbents, tandems, trailers, golf carts, and assisting technologies such as electric scooters and motorized wheelchairs. In addition, the level of experience of the users impacts their operational characteristics on our roadway and trail facilities. Transportation facility planners and designers have little knowledge of these emerging road users' operational and design characteristics.

Also, currently very little is known regarding these users' crash experience either on trails or along roadways. For example, data from the Consumer Product Safety Commission show that in 2000, hospitals reported more than 33,000 scooter-related emergency room visits and two fatalities. Unfortunately, these hospital reports provide little detail regarding the type or condition of the facility on which the crashes occurred or the preceding actions of the involved person(s).

Objectives:
The objectives of this study are:

  1. to determine the characteristics of these newer types of road and trail users that may affect facility design, operation, and safety;

  2. to investigate the safety of these users in the environments in which they operate; and

  3. to consolidate this information in a usable format for individuals responsible for the planning, design, operation, and maintenance of pedestrian and bicycle facilities.

In-House Research

1. Comparison of Pedestrian Crossing Signals Study
FHWA researchers conducted this study during early 2001 in the Signsim laboratory at Turner-Fairbank Highway Research Center. Forty-eight subjects were recruited from the FHWA subject pool to participate in the study. Half were male, half were female. Six experimental pedestrian crossing signals and the standard MUTCD crossing signal were tested and compared, for a total of seven pedestrian crossing signals, for ease of understanding and comprehension. Of the six experimental signals, the Countdown pedestrian crossing signal resulted in the highest understanding and comprehension rates, i.e., high rates of comprehension about when the signal told the pedestrian to start crossing and how much time he or she had in which to cross. The standard MUTCD crossing signal resulted in one of the lower rates of understanding and comprehension, with some confusion occurring about the meaning of the flashing hand when it appears simultaneously with the walking person symbol. The results of this study indicated that further research should be conducted on the Countdown pedestrian signal.

2. A Comparison of Pedestrian Countdown Signal Timing Phases Study
FHWA researchers will conduct this study during early 2002 in two phases. The first phase will consist of researches collecting video data and feedback in the field at a number of Countdown signalized intersections in the Northern Virginia area. The field research will gather data on motorist and pedestrian behaviors at the intersections, and feedback about comprehension from pedestrians who have just completed crossings at these intersections. The intersections of interest are located in Alexandria, Ballston, and Fairfax. The second phase will consist of laboratory testing a Countdown crossing signals, demonstrating six different signal timing strategies concerning the Walk, Cautionary and Don't Walk phases. Each of the six experimental Countdown timing strategies will be compared against the standard MUTCD pedestrian crossing signal to determine pedestrians' rates of comprehension and response times. The outcome of this study should consists of a set of recommended guidelines for design of a standard MUTCD signal that incorporates the Countdown feature.

3. In-Pavement Crosswalk Lighting Studies
FHWA researchers have begun preliminary field data collection concerning an in-pavement crosswalk lighting installation that will occur in Arlington, VA at Memorial Bridge in early 2002. Researchers have already captured preliminary video data to determine the scope of what will be required for the before data collection at this location. The preliminary data have established that crosswalk markings and related signing at this location are not readily perceived by motorists at this location, and that pedestrians have to cross multiple lane that feed in and out of a traffic circle located at the Arlington entrance to the bridge. Findings from the before data collection will be summarized and discussed with FHWA highway research engineers. Following installation, FHWA researchers will collect after data at 3 month, 6 month, and 13 month intervals. FHWA researchers will also conduct laboratory evaluations later in 2002 of in-pavement crosswalk lighting systems to determine comprehension requirements, luminance requirements, etc. This research should result in the development of design guidelines for transportation engineers.

The contractor, Alta Transportation Consulting, has posted a draft report at www.altaplanning.com.

  12. Updates to the Manual on Uniform Traffic Control Devices (MUTCD), when they occur, can be found at http://mutcd.fhwa.dot.gov. The Millennium Edition has been published and updates are expected on an annual basis.

  13. A Public Engineering Outreach Campaign is being developed to improve the behavior and performance of highway users. This will be done by focusing on those highway-related issues that a motorist and a pedestrian have control over: improved user practices and compliance with traffic control devices. Campaign materials will be developed by fall 2002 and could be piloted tested in 2003/4. See contact information below.

  14. Pedestrian Safety Engineering and Intelligent Transportation System-based Countermeasures will be deployed in local jurisdictions to evaluate their effectiveness in reducing pedestrian fatalities, injuries, and conflicts. Phase 1 of the Cooperative Agreement develops a plan addressing pedestrian safety problem identification and countermeasure selection within the chosen locality. Phase 2 is optional at the discretion of the Government and consists of implementing the plan. The intent of the Cooperative Agreement is (1) to demonstrate the effectiveness of the pedestrian safety program plan in reducing pedestrian fatalities, injuries, and conflicts, and (2) demonstrate the plan's portability to other jurisdictions within the United States. Problem Identification will be completed in 2002 with field testing and evaluation to be completed between 2002-2005. At present, we are working with two communities - Miami Dade and Las Vegas. See contact information below.

  15. Pedestrian Safety Countermeasure Selection System focuses on the development of an expert system database containing details associated with crashes between motor vehicles and pedestrians. With the expert system, safety practitioners can generate potential countermeasures to address problems identified in their local jurisdiction. This effort will be beta tested in the spring of 2002 and released in fall 2002. See contact information below.

  16. The Bicycle and Pedestrian University Graduate Course will be finalized by Spring 2002. The course teaches future professionals how to integrate pedestrian and bicyclists accommodations into the planning and design of transportation facilities. The university course covers an extensive range of issues in nonmotorized transportation design, including pedestrian and bicyclist crash types and related safety countermeasures, pedestrian accommodation at intersections, traffic calming techniques, and bicycle facility design. It is hoped that the professors would integrate the course materials into their curriculum, and/or offer it as a stand alone graduate course. See contact information below.

  17. National Educational Curriculum for Bicyclists: This curriculum was developed for all ages and levels of cyclists. The curriculum identifies the skills and knowledge that bicyclists of different ages need to have and match these needs to already existing resources. The curriculum consists of a matrix targeting audiences that are the focus of various bicyclist training programs and a resource catalog designed to assist users in identifying relevant training materials under recommended topics for the target audiences. A web page is being developed that will be housed on the www.bicyclinginfo.org page. The Web page will include the curriculum, an interactive database, and a good practices guide for those designing their own courses. The Good Practices Guide, which tells of several successful bicycle safety education programs and tips for implementing your own program, will be available in hard copy by March. The curriculum and associated products will be housed on the web page by February. See contact information below.
