MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Stability of traffic flow with distributed delays modeling the memory effects of the drivers
Rifat Sipahi, Fatihcan M. Atay and Silviu-Iulian NiculescuAbstract
Stability analysis of a single-lane microscopic car following model is studied analytically from the perspective of delayed reactions of human drivers. In the literature, the delayed reactions of human drivers are modeled with discrete delays, which assume that drivers make their control decisions based on the stimuli they receive from a point of time in the history. We improve this model by introducing a distribution of delays, which assumes that the control actions are based on information distributed over an interval of time in history. Such an assumption is more realistic as it takes into consideration the memory capabilities of the drivers, and addresses the inevitable heterogeneity of the drivers’ variations in their delay times. We calculate exact stability regions in the parameter space of some realistic delay distributions. Case studies are provided demonstrating the application of the results.
