Real-Time Delay Measurement and Intersection Analysis System
Two intersection delay measurement approaches are developed, and a framework for a real-time traffic signal data collection and intersection operational analysis system is presented. The...
A Method for Reviewing and Assessing PASSER II and TRANSYT-7F Signal Timing Optimization Outputs
The development of traffic signal timing plans is a common task. Some of the traffic software programs are the Arterial analysis package (AAP), the Progression Analysis and Signal System...
An Expert System Analysis of the Signal Operational Analysis Package Results
An expert system is a type of artificial intelligence program that captures the human knowledge which is involved in making a decision. Expert systems are very suitable for solving problems...
Use of TRAF-NETSIM to Estimate the Traffic Impacts of an Urban-Resort Area Development
Urban-resort areas are concentrated visitor destination districts that are located within or in close proximity to urban areas. The combination of visitor-related and urban activities...
The Wizard of Helpful Intersection Control Hints
The methodology for making traffic control decisions is the subject of this paper. There exists a body of knowledge supporting a sound decision making process, but it requires the use...
