Considering weather in simulating traffic

André-Gilles Dumont, Ashish Bhaskar, Minh Hai Pham, Sofia Samoili

The impact of weather on traffic and its behavior is not well studied in literature primarily due to lack of integrated traffic and weather data. Weather can significant effect the traffic and traffic management measures developed for fine weather might no ...

Methodology for Developing Real-time Motorway Traffic Risk Identification Models Using Individual Vehicle Data

André-Gilles Dumont, Ashish Bhaskar, Edward Chung, Minh Hai Pham

Most of existing motorway traffic safety studies using disaggregate traffic flow data aim at developing models for identifying real-time traffic risks by comparing pre-crash and non-crash conditions. One of serious shortcomings in those studies is that non ...

Fusing Loop Detector and Probe Vehicle Data to Estimate Travel Time Statistics on Signalized Urban Networks

André-Gilles Dumont, Ashish Bhaskar, Edward Chung

This article presents a methodology that integrates cumulative plots with probe vehicle data for estimation of travel time statistics (average, quartile) on urban networks. The integration reduces relative deviation among the cumulative plots so that the c ...

Random Forest Models for Identifying Motorway Rear-End Crash Risks Using Disaggregate Traffic Data and Meteorological Information

André-Gilles Dumont, Ashish Bhaskar, Edward Chung, Minh Hai Pham

This paper presents an approach to develop motorway Rear-End Crash Risk Identification Models (RECRIM) using disaggregate traffic data, meteorological data and crash database for a study site at a two-lane-per-direction section on Swiss right-hand driving ...

Estimation of travel time on urban networks with midlink sources and sinks

André-Gilles Dumont, Ashish Bhaskar, Edward Chung

This paper presents a methodology for estimation of average travel time on signalized urban networks by integrating cumulative plots and probe data. This integration aims to reduce the relative deviations in the cumulative plots due to midlink sources and ...

A methodology (CUPRITE) for urban network travel time estimation by integrating multisource data

Ashish Bhaskar

Travel time is an important network performance measure and it quantifies congestion in a manner easily understood by all transport users. In urban networks, travel time estimation is challenging due to number of reasons such as, fluctuations in traffic fl ...

Analytical Modelling and Sensitivity Analysis for Travel Time Estimation on Signalised Urban Network

André-Gilles Dumont, Ashish Bhaskar, Edward Chung

This paper presents a model for estimation of average travel time on signalized urban lane using cumulative plots. The plots are generated based on the availability of data: a) case-D, for detector data only; b) case-DS, for detector data and signal timing ...

Development and implementation of the areawide Dynamic ROad traffic NoisE (DRONE) simulator

Ashish Bhaskar, Edward Chung

This paper discusses the areawide Dynamic ROad traffic NoisE (DRONE) simulator, and its implementation as a tool for noise abatement policy evaluation. DRONE involves integrating a road traffic noise estimation model with a traffic simulator to estimate ro ...

Methodology for Travel Time Estimation on a Signalised Arterial

André-Gilles Dumont, Ashish Bhaskar, Edward Chung

This paper presents the development and testing of a methodology for estimation of average travel time on signalised urban networks. The methodology considers the classical analytical procedure, where average travel time on a study link is estimated as the ...
