Abstract: Mixed vehicle traffic of driver-operated vehicles (DVs) and autonomous vehicles (AVs) on roadways in the future will result in four interaction types between these two vehicle types, impacting current intersection sight ...

Abstract: Modeling efforts for driver behavior parameters on horizontal curves have mostly focused only on the 85th percentile value. However, predicting whole distributions would help improve alignment design by allowing reliability-based ...

Abstract: Design guidelines for freeway ramp entrances are based on speed and acceleration data collected before 1950. This study investigated driver behavior over the entire freeway entrance area, including the ramp, the acceleration ...

Abstract: Access to freeways is provided through interchanges to maintain the design concept of uninterrupted traffic flow. Therefore, provision of an appropriate entrance ramp and acceleration lane geometry that allows the entering ...

Abstract: This paper presents a state-of-the-art review of recent developments in three-dimensional (3D) analysis for transportation planning and highway design. As background, the concept of dimension is briefly discussed and ...
