Crash Rates At Intersections, Eric R. Green, Kenneth R. Agent
Crash Rates At Intersections, Eric R. Green, Kenneth R. Agent
Kentucky Transportation Center Research Report
The objectives of this study were to develop a database of intersections, match traffic crashes to these intersections, calculate crash rates for various types of intersections, and identify intersections with the highest crash rates. A procedure was used to: a) identify intersections, b) assign crashes to these intersections, c) determine entering traffic volume, d) calculate a crash rate for each intersection, and e) calculate a critical rate factor (CRF) for each intersection.
About 7,000 intersections were identified with almost 19,000 crashes related to these intersections for the three-year period of 2000 through 2002. The analysis identified 428 intersections that had …

Highway Crash Site Management, Monica L. Barrett, Jennifer R. Walton
Kentucky Transportation Center Research Report
Traveler delay is the problem most often associated with highway crashes, but by far the most serious problem is the resulting secondary crashes that occur. Another related issue is the danger posed to response personnel serving the public at the scene of a crash. The longer a crash is in place, the longer the responders are vulnerable and exposed to injury.
The Kentucky Transportation Center, in cooperation with the Kentucky Transportation Cabinet, developed a checklist and interagency workshop to address ways to secure and coordinate the resources necessary to restore the roadway’s operation in a safe and timely manner. The …

Traffic Signals In School Zones, Kevin S. Lee, Darcy M. Bullock
JTRP Technical Reports
Traffic signals are used to control the right of way at intersections. Strict engineering guidelines are published in the Manual on Uniform Traffic Control Devices (MUTCD) that engineers use to determine if a traffic signal is “warranted”. The warrants provide consistent national balance between mobility, safety, efficiency, and costs. However, signalized intersections are often viewed by the general public as safer then unsignalized intersections. This belief is often heightened when there are personal injuries and even higher when children are involved. Parents, city officials, and local interest groups often vigorously request the installation of a traffic signal. After these requests …

Evaluation Of Safety Enforcement On Changing Driver Behavior - Runs On Red (1 Of 2 Volumes), Andrzej P. Tarko, Naredla Lakshmi Reddy
JTRP Technical Reports
Red light running (RLR) is a dangerous act. Approximately 22% of urban crashes at signalized intersections are caused nationwide by RLR. Nearly 1,036 deaths were caused nationwide by RLR in the year 2000. Indiana had no previous research conducted in this area; therefore, this research was aimed at estimating the RLR problem in Indiana. The other objectives of this research included: learning drivers’ opinions on the problem, studying the effectiveness of selected countermeasures, and studying the legal issues related to photo-enforcement. A crash statistics study, telephone survey, and extended monitoring of a selected intersection were the three major approaches chosen …
