Low Cost, High Return
by Dean M. Larsen, Fred N. Ranck, and John McFadden
A new FHWA outreach campaign educates teens on work zone safety.
Improving roadway safety is one of the Federal Highway Administration's (FHWA) "vital few" goals. Meeting this goal means not only focusing on the interstates and the National Highway System highways but also addressing safety concerns on local roads in communities across the country.
"According to 2004 FARS [Fatality Analysis Reporting System] data, approximately 58 percent of the Nation's roadway fatalities occurred on rural roads, and a number of these roads are locally owned," says Leslie Wright, manager of the Local/Tribal Road Safety Program in FHWA's Office of Safety. "With this in mind, making safety a priority on locally owned and rural roads by and large is crucial to reducing the Nation's 42,636 roadway deaths annually."
Reducing the number of highway fatalities and implementing safety improvements are ongoing challenges for local agencies contending with modest budgets that limit personnel, equipment, and other resources for constructing and maintaining roadway modifications. To improve safety, local agencies need access to best practices that are within their budgets and tailored to their needs.
In Kentucky, the rate of fatal crashes is climbing, according to recent research by the Kentucky Transportation Center (KTC), which includes Kentucky's Local Technical Assistance Program (LTAP), housed within the University of Kentucky's College of Engineering. As reported in the spring 2005 issue of the center's newsletter, The Link, Kentucky is among the top five States in the Nation in terms of fatalities resulting from roadway hazards on rural two-lane roads. However, Kentucky's new Safety Circuit Rider (SCR) pilot program is helping improve safety on the State's rural roads.
The Kentucky SCR program is a mobile outreach effort that provides face-to-face workshops on transportation-related safety for local government staff. According to The Link newsletter, Kentucky is focusing on three primary areas: reducing road departures (run-off-the-road collisions with fixed objects), intersection collisions, and collisions involving pedestrians.
The program's success is the result of technical support, training, and technology transfers that involve Federal, State, and local partners working together to implement small-scale, affordable, and perhaps overlooked safety improvements on locally managed roads. The counties involved in Kentucky have seen a marked improvement in safety through reductions in injuries and fatalities. Other States including Florida, Iowa, and Minnesota also have found success in similar programs.
Low-Cost Safety Improvements
Kentucky's SCR pilot program is an outgrowth from a series of workshops on low-cost safety improvements (LCSIs) launched by the FHWA Resource Center at the request of FHWA's Missouri Division Office. LCSIs are projects that cost $10,000 or less to implement.
Typical LCSIs include removing vegetation, including trees that pose a hazard (although such trees also might be delineated with object markers); building up shoulders to eliminate dropoffs; and adding signage to warn of unusual roadway features, such as sharp curves, or to accentuate the four corners of bridges. In some cases, improvements that are more intensive such as bridge widening also can be implemented.
Implementing Kentucky's SCR
After Kentucky's LTAP was awarded SCR funding through FHWA's Office of Safety, the staff immediately began forming partnerships with organizations including local Area Development Districts (ADDs) to make the most of the limited dollars. Freddie Goble, a retired transportation planner, joined the LTAP staff to launch the program. Along with Terry Chism, a transportation safety engineer with FHWA's Kentucky Division Office, Goble attended an FHWA-sponsored training program on LCSIs in 2004 and later customized those materials for a Kentucky-specific 1-day workshop on LCSIs.
According to the Kentucky Council of Area Development Districts, Kentucky's counties are grouped into 15 regions, or ADDs, which serve as forums, clearinghouses, and technical centers for the regions. The ADDs would prove instrumental in helping implement the SCR program.
To launch the SCR initiative in Kentucky, a steering committee first identified the six counties with the worst crash records. Then, each of the six ADDs with the highest crash records hosted a workshop to disseminate best practices and share information on LCSIs. All counties in a host ADD were invited to send transportation professionals to the workshop, with representatives from the Kentucky Transportation Cabinet attending as well.
After the county representatives learned about the LCSI practices, the judge of each target county (an elected official who serves as the chief executive officer of the county but has no actual judicial power) was asked to select two roads to receive a road safety audit. The audits would help the counties pinpoint the specific safety issues on their chosen roads and select appropriate countermeasures.
To conduct the audits, KTC's Goble (the SCR and oncall safety expert) accompanied county representatives and, when available, traffic engineers from the Kentucky Department of Highways (KYDOH) for a drive along the selected high-crash roads. During the drive, the team pointed out safety concerns and discussed possible low-cost corrective measures. The team also looked at crash locations for possible corrective measures.
For example, the audit determined that an intersection near the town of Hazard needed several improvements to increase safety. Using the information they learned during the safety audit, Denny Ray Noble, Perry County judge/executive, and Charles Cowell, deputy judge/executive, worked out a partnership with the KYDOH office in Jackson to implement several LCSIs at the junction of KY 15 and Crawford Mountain Road. Through the partnership, the Perry County Road Department removed approximately 382 cubic meters (500 cubic yards) of earthen embankment that was blocking motorists' views looking northward on KY 15 from Crawford Mountain Road.
The removal enabled the department to widen the existing roadway to accommodate a left-turn lane. The material from the embankment was used to fill a 10.6-meter (35-foot)-deep ravine directly adjacent to Crawford Mountain Road near the intersection. Perry County also widened the shoulder of KY 15 to accommodate an acceleration lane. The local agency provided the labor, equipment, and materials for excavating, widening, removing guardrails, and filling the ravine. KYDOH paved the road and applied the pavement markings. "This is an excellent example of partnerships to improve safety," FHWA's Chism says.
Later, after the safety improvements were implemented, Goble reviewed the roads and verified that the improvements were made correctly. Noble says the number of crashes at the Crawford Mountain Road intersection declined significantly after the improvements were made, making the project one of the best examples of the success of the Kentucky SCR program.
Goble attributes much of this success to the availability of accurate geographic information system (GIS) maps of local roads. Combined with precise crash locations derived from global positioning system (GPS) technology, the GIS maps enabled State officials to compile the initial list of local roads with the highest number of crashes.
A Little Adds Up to a Lot
According to FHWA's Chism, the results of the Kentucky SCR program far exceeded anyone's expectations. "By the end of the first phase of the program in June 2005, Kentucky ended up improving 39 roads and spending only $235,000 on the safety improvements," Chism says. "Once the counties saw that they could do little things to improve safety, several expanded the program. All of the improvements were made with county funds and resources. I was amazed at the counties' responses and the excitement they demonstrated."
Some were so quick to make improvements that Goble was able to incorporate before and after photographs of their work into the workshop for the next county. With workshops occurring within 1 week of each other, the turnaround times were dramatic.
The public and media also responded well to the visible improvements in local roads. According to Goble, local newspapers sent reporters to ride along on the safety audits and frequently printed the before and after photographs.
Making the necessary improvements often required county personnel to access adjacent private land to cut down trees that posed a safety hazard. "The private property owners were very cooperative," Goble says. He attributes their support to the participation of the county judges, who approached the landowners and explained the need for the safety improvements.
In other projects, creative bargaining helped. "One landowner, when we told him we wanted to cut down several very old trees, thought about it and said, 'If you cut the trees, trim them, and stack them over there where I'm building a barn, you have my permission,'" Goble recalls. The county personnel readily agreed.
Tim Conley, Morgan County judge/executive, is pleased with the results of the Kentucky SCR program. "One of the roads we looked at, a new road in fact, had 13 reported [crashes] between 2000 and 2004. In 2005 there were no [crashes] on that road. It cost us $800 to make the improvements," Conley says. Even better, he reports that Morgan County made improvements on 8 to 10 additional roads outside the program, emphasizing that county crews now know what to look for.
Conley's constituents have let him know that they approve as well. "I had someone come up to me and tell me that one of the roads has improved 100 percent as a result of this work," he says.
James L. "Buddy" Gallenstein, the judge/executive for Mason County, says that the GPS crash data provided by the SCR program has "opened my eyes" to some problem roads in the county. According to Gallenstein, his office routinely receives crash data for highways and major roads, but the SCR program offers access to the same data at the local level for the first time.
"We plan to assess our roads on an annual basis now," Gallenstein says. He and his road supervisor also will be looking at opportunities to implement LCSIs when they make their annual priority assessments for roads.
The Kentucky SCR program is now in its second phase, with six more counties identified to receive workshops and safety audits. Although the grant covered only a 1-year pilot program, the Kentucky Transportation Cabinet pledged sufficient funding to carry the program through 2006, and possibly 2007, reports Patsy Anderson, director of the Technology Transfer Program at KTC. Continued Federal funding for the program is uncertain at this time.
Lance Meredith recently replaced Goble as Kentucky's SCR. Meredith brings to the position 30 years as a traffic engineer with KYDOH and 2 years as a transportation planner at a Kentucky ADD. Twelve additional counties have been identified as focus counties, and many other jurisdictions are joining the program on a volunteer basis. LTAP also is taking steps to improve crash reporting systems on rural roads.
Partnerships Yield Results
Kentucky's program combined need, motivation, expertise, funding, and public support to achieve rapid success. Partnerships with stakeholders such as FHWA, the Kentucky Transportation Cabinet, local agencies, and the public, exchanging ideas and resources to launch the SCR program, were instrumental in helping Kentucky to improve safety on its rural roads.
