Traffic Assignment Simulation Analysis considering the Drivers' Travel Time Perception Updating Process under the Travel Time Information

A micro-simulation model system of departure time using a perception updating model under travel time uncertainty

Existing microscopic traffic models have often neglected departure time change as a possible response to congestion. In addition, they lack a formal model of how travellers base their daily travel decisions on the accumulated experience gathered from repetitively travelling through the transport network. This paper proposes an approach to account for these shortcomings. A micro-simulation appro...

Travel-time Measuring System for Efficient Traffic Information Service

OVERVIEW: Traffic control systems for automobile traffic are being set up that allow more advanced traffic signal control according to traffic conditions and provide drivers with the real-time traffic information that they need to make their own driving decisions. The traffic information required by the driver includes traffic regulations, degree of congestion, parking space availability and so...

Quality of Real-time Travel Time Information

Travel Time Use in the Information Age

This paper, focused primarily on UK data and debates, considers the potential significance of travel time use within past, present and future patterns of mobility. In transport scheme appraisal, savings in travel time typically represent a substantial proportion of the benefits of a scheme – benefits used to justify its often enormous financial costs. Such benefits are founded on the assumption...

Modeling Travel Time Uncertainty in Traffic Networks

Uncertainty in travel time is one of the key factors that could allow us to understand and manage congestion in transportation networks. Models that incorporate uncertainty in travel time need to specify two mechanisms: the mechanism through which travel time uncertainty is generated and the mechanism through which travel time uncertainty influences users’ behavior. Existing traffic equilibrium...
