Estimating travel time reliability in urban areas through a dynamic simulation model

A Multi - State Travel Time Reliability Model

Travel time unreliability is an important characterization of transportation systems. The appropriate modeling and reporting of travel time reliability is crucial for individual travelers as well as management agencies. In this paper, a novel multi-state model is proposed for travel time modeling and reporting. The model advances travel time modeling in two aspects. First, the multi-state model...

Understanding congested travel in urban areas.

Rapid urbanization and increasing demand for transportation burdens urban road infrastructures. The interplay of number of vehicles and available road capacity on their routes determines the level of congestion. Although approaches to modify demand and capacity exist, the possible limits of congestion alleviation by only modifying route choices have not been systematically studied. Here we coup...

MAUTC Report Topic: Time Dependent Estimation of Travel Time in Real Time in Urban Areas by

The objective of this project is to quantify and evaluate a wide range of methods that would estimate the travel times in urban areas under real time conditions taking into consideration that the traveler crosses the links of his and her route at different points in time, thus initiating the time dependency situation.

A Freeway Travel Time Reliability Study

The objective of this study was to identify measures appropriate to estimate travel time reliability and apply them to study the reliability of travel time under varying freeway operating conditions. More specifically, a case study was undertaken to study travel time reliability along the I-65 corridor in the State of Alabama. The objectives of this study were to: a) Calculate reliability metri...
