Abstract:

Driver behavior is investigated at the aerial road, where two different roads meet each other at the junction. The performance measurement of congestion such as speed, time headway, and the saturated flow rate is calculated. Their influences due to change in the road's geometric properties under heterogeneous flow conditions were analyzed in this study. Vehicles are more stimulus to merging traffic and is the leading cause of congestion at junction. It is concluded that speed stimulates time headway and driver interaction at junctions, which results in a capacity drop and increases the risk of accidents. Field data is recorded at a three-leg intersection. Speed drops upstream while the vehicle downstream accelerates easily to attain the desirable speed ahead.

Keywords:

Speed, Time Headway, Driver Behaviour, Junction, Heterogeneous Flow.
