The need of maintaining safety of motorists and workers during periods of construction activities on interstates has prompted the Indiana Department of Transportation (INDOT) to initiate a study aimed at improving the safety in work zones on rural interstates. The two main objectives of the project are 1) determine if active warning devices or improved signing have an impact in work zone safety and 2) determine if it is appropriate to consider temporary roads and bridges during construction activity on interstates in an effort to maintain two lanes open at all times. This report describes the methods used to meet …

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 …

Roadside cross-drainage culverts have been found to affect vehicle accident injury levels. As a result, highway designers have commonly used three safety treatments to protect errant motorists from striking culvert openings. These safety treatments have included: culvert extension, guardrail installation, and the application of safety grating. However, the identification of the most appropriate safety treatment for roadside culverts may be challenging; accident costs may dramatically change under different road and traffic characteristics. The purpose of this study was to estimate accident costs for a wide range of road and traffic scenarios and then define the safest treatment (i.e., treatment with …
Modeling Roadside Safety Hazards To Predict Annual Crash Cost To Encroaching Vehicles In Rural Road Networks, Isidro Delgado
Modeling Roadside Safety Hazards To Predict Annual Crash Cost To Encroaching Vehicles In Rural Road Networks, Isidro Delgado
USF Tampa Graduate Theses and Dissertations
Roadside crashes account for a large portion of total fatal crashes that occur annually in the United States. About 30% of those fatalities are the result of single vehicle run-off-road crashes. A large proportion of these fatal crashes occur in rural roads when vehicles depart from the travel lane and collide with trees or other roadside safety hazards. Many of these run-off-road accidents occur in local roads that carry traffic volumes between 1,000 and 20,000 vehicles per day. Many of these roads are part of the jurisdiction of county authorities faced with the dilemma of having too many "potentially dangerous" …
Investigation Of The Effective Use Of Warning Lights On Indiana Department Of Transportation (Indot) Vehicles And Equipment, Bob Mccullouch, Brandon Stevens
Investigation Of The Effective Use Of Warning Lights On Indiana Department Of Transportation (Indot) Vehicles And Equipment, Bob Mccullouch, Brandon Stevens
JTRP Technical Reports
This study was requested by INDOT to determine if current lighting packages used on INDOT maintenance vehicles, specifically snow plow vehicles, can be improved with other commercially available products. Different light products were obtained from various vendors, mounted on INDOT vehicles, and visual comparisons were performed under various lighting and weather conditions by a team of observers. The comparison evaluations were performed revealing that other light packages, LED models for most options, were brighter and certain colors more visible. The preferred light models are recommended. These recommendations were forwarded to appropriate individuals that make these decisions at INDOT. Implementation is …
