Safety Comparison of E/P Left-Turn Signal Displays

Access Control to Projects Via Raised Islands
When addressing driveway maneuvers at a new development, alleged ailments Must be quantified before drafting a cure. If a problem is anticipated, alternative solutions should be investigated,...

A Microcomputer Package for Interrelating the Highway Capacity Manual and SOAP 84
There is some evidence that the SOAP program may replicate signalized intersection delay more realistically than the 1985 Highway Capacity Manual (HCM) operational procedure for signalized...

Traffic Simulation at Unsignalized Intersections Using GPSS
This paper develops a simulation model, based on actual field data, that simulates the minor street left turn movement at a STOP-controlled T-intersection. This simulation model predicts...

Considerations in Applying the 1985 HCM Procedures
The paper examines the impact of critical assumptions in the 1985 Highway Capacity Manual (HCM) procedures on the resulting measures of effectiveness -- volume/capacity ratio, delay, and...

Modeling Permissive Movements in TRANSYT-7F
Traffic Network Study Tool (TRANSYT-7F) is one of the most widely used traffic flow analysis and traffic signal timing optimization models in the United States and elsewhere. Through 'Release...

Highway Accident Collision Diagrams on a Microcomputer
Collision diagrams of highway accidents are schematic exhibits that illustrate the location of each accident with respect to the highway geometric features. The types of accidents; such...

POSIT—An Interactive Timing Optimization Program
A window-oriented, microcomputer-based signal optimization program called POSIT (Program for Optimizing Signalized Intersection Timing) has been developed that provides traffic engineers...
