Urban-scale traffic monitoring plays a vital role in reducing traffic congestion. Owing to its low cost and wide coverage, floating car data (FCD) serves as a novel approach to collecting traffic data. However, sparse probe data represents the vast majority of the data available on arterial roads in most urban environments. In order to overcome the problem of data sparseness, this paper propose...

Project Title: Reducing Traffic Congestion and Fuel Emission through a Minimal Cost, Self-Tuning Closed-Loop Progression System URL: http://tti.tamu.edu/documents/0-4729-2.pdf 16. Abstract Closed-loop systems are widely implemented in Texas arterials to p...

A mixed traffic flow feature is presented on urban arterials in China due to a large amount of buses. Based on field data, a macroscopic mixed platoon flow dispersion model (MPFDM) was proposed to simulate the platoon dispersion process along the road section between two adjacent intersections from the flow view. More close to field observation, truncated Gaussian mixture distribution was adopt...

This study aims to identify influencing factors of traffic accidents in Japanese major road through factor analysis and regression analysis for each accident type, considering their characteristics of rare event. The database consists of 5-year accident record and relevant road traffic condition data in major road sections in Aichi Prefecture which includes the third largest conurbation area of...

For having better and up to date traffic information access, spatio-temporal GIS for transportation (TGIS-T) needs to interact with the intelligent transport systems (ITS). Advanced traffic management systems (ATMS) is one of the components of the ITS and predicts traffic congestion and provides real time traffic information and optimal control strategies for freeways and arterials. ATMS needs ...

The two-fluid model for vehicular traffic flow explains the traffic on arterials as a mix of stopped and running vehicles. It describes the relationship between the vehicles' running speed and the fraction of running vehicles. The two parameters of the model essentially represent 'free flow' travel time and level of interaction among vehicles, and may be used to evaluate urban roadway networks ...

Work zones generate significant congestion in urban centers, yet the influence of various capacity factors arterials and intersections are poorly understood. This paper analyzes following on arterial intersection work zone from 22 intersections: heavy vehicle flow, percentage, length, maximum speed limit, entrance lane width, left turn volumes, exit width reductions, length width. An was modele...
