Determining PCU values in signalized circular intersections for certain vehicle types

Modeling Multiple–Vehicle Property Damage Collisions in Urban Signalized Intersections

Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...

Isolated Signalized Intersections

New Detection System for Rural Signalized Intersections

Project Summary Report 0-4022-S – 1 – Traffi c engineers are often faced with operational and safety challenges at rural, high-speed signalized intersections. Vehicleactuated control, combined with multiple advance detectors, is often used to improve operations and safety. However, this type of detection and control has not always eliminated rear-end or right-angle crashes. Crashes sometimes co...

Delay Variability at Signalized Intersections

Delays that individual vehicles may experience at a signalized intersection are usually subject to large variation due to randomness of traffic arrivals and interruption caused by traffic signal control. While such variation may have important implications for the planning, design and analysis of signal controls, currently there is no analytical model available to quantify it. This paper descri...
