Abstract: Adequate sight distance is an important factor needed to provide safe and efficient operation of left-turn movements at signalized intersections. This factor becomes more crucial for left turners attempting this maneuver ...

Abstract: Delay is an important measure of effectiveness in traffic studies; it represents the direct cost of fuel consumption and indirect cost of time loss to motorists. The 1985 Highway Capacity Manual (HCM) used delay as the ...

Abstract: The growing volume of hazardous‐materials shipments and the potential consequences of a materials release have raised public concern and scrutiny over the safe handling and transport of hazardous cargo. This has prompted ...

Abstract: At signalized intersections where protected left turn signals are not provided, simultaneous opposing left-turn vehicles may cause insufficient sight distance for each other. There is a lack of literature presenting left-turn ...

Abstract: A great deal of research has been conducted on Central Florida toll roads to better understand the characteristics of the tolling operation. In this paper, the use of the toll plaza queuing model SHAKER is calibrated to ...

Abstract: A large deal of research has been conducted on toll roads to better comprehend the characteristics of the tolling operations. Several researchers indicated that toll-lane processing time (or service time) is the most ...

Abstract: Modeling traffic at toll collection facilities can assist in computing plaza capacity and performance. It may help planners and operators decide on which lane configurations are appropriate for specific hourly approach ...

Abstract: The benefits and costs of implementing a bus preemption system at isolated intersections and at intersections forming an open arterial network were investigated. Trade‐off analyses were performed on measures of road user ...

Abstract: With the advances in technology and communication devices, such as smartphones and in-vehicle systems, being distracted has become the norm in our society. Those distractions cause a tremendous cognitive load, especially ...

Abstract: This study uses the two-fluid model for traffic flow, to examine driver behavior during both wet and dry pavement conditions and various times of the day. It was found that parameters in the two-fluid model known to be ...
