Empirical Investigations of Driving Behavioural Phenomena in Heterogeneous Traffic

Roads worldwide are rapidly becoming heterogeneous with varying vehicle technologies, levels of connectivity, levels of autonomy, levels of access to information, vehicle sizes, etc. A glimpse into strategies for understanding and modeling such traffic conditions may be gained from developing countries where the traffic is heterogeneous with respect to road geometry, vehicles, and driver behavior characteristics. This presentation provides an overview of two studies to draw insights into the driving behavioral phenomena in heterogeneous traffic conditions. The first part of the presentation discusses the development of composition-specific fundamental diagrams and strategies to reduce scatter in the congested branch. The second part of the presentation presents the non-anisotropy phenomena in heterogeneous traffic. These studies provide a more nuanced understanding of driver behavior characteristics for developing better traffic management strategies in heterogeneous traffic conditions.
