Abstract: The objective of this study consists of assessing the application of generalized additive models (GAMs) for estimating accident modification factors (AMFs). GAMs are a new type of models that have been recently introduced ...

Abstract: Understanding the underlying relationship between crash injury severity and factors such as driver’s characteristics, vehicle type, and roadway conditions is very important for improving traffic safety. Most previous studies ...

Abstract: Left-turn gap acceptance at an unsignalized intersection is dependent on many factors. The Highway Capacity Manual (HCM) uses a single value of critical gap for all types of intersections; however, this may be oversimplistic ...

Abstract: This study contributes to research and practice by demonstrating the use of a composite measure, a bikeability index, to facilitate the use of and improve the performance of direct demand models for bicycle traffic, ...

Abstract: In the construction of pipe jacking, the calculated jacking force is often greater than the actual measured value. In particular, the deviation between calculated and actual frictional resistance is large. Moreover, during ...

Abstract: This paper studies the effect of bicycles on intersection operations for those intersections where bicycle traffic causes the most disturbances to vehicular traffic. By studying different states of bicycles crossing a ...
