Abstract

Travel time is a vital traffic parameter which can be easily perceived by any road user. The dynamic prediction of travel time is challenging in India due to traffic heterogeneity and disordered nature of propagation. A model was developed to estimate travel time dynamically on a highway with an access road. Macroscopic modeling was chosen in order to make the formulations simple and computationally effective which is always desirable for any real time applications. The model was implemented and validated with the traffic data from the field. The travel time obtained by the model was compared with other classical models and a simulation study was carried out in VISSIM software to study the behavior of model under diverse traffic scenarios. The methodology proposed in this paper can be extended to any link having more number of entry and exit points using modified traffic stream models
