Abstract

Three new models to estimate travel times from traffic counts are developed in this paper, which can improve the accuracy of estimated travel times. One model is based on the concept that vehicle speeds change even within the same time interval, and estimates travel times with some estimated vehicle trajectories. The other model changes a shape of a traffic detector territory to a rhombus. These models are constructed by modifying the Temporal and Spatial Transition (TST) model. By applying these models to Nagoya Expressway in Aichi, Japan, it was found that the estimation accuracy of travel times was improved. For the covering abstract see ITRD E134653.
