Microcomputer Tools for Small Area Planning Analysisby G. Scott Ferguson, Wilbur Smith Associates, United States,
Abstract: A microcomputer software concept is presented which integrates the traffic engineering and planning functions of traffic impact studies. A collection of suggested ideas for better integration and improved features is presented. The concept for traffic impact software includes: graphic interfaces for coding networks, graphic quality turning movement diagrams, and database management features. Calculation modules include a variety of analytical tools: unsignalized and signalized intersection analyses (planning as well as operations and design calculations), traffic signal warrants, traffic count summaries, o/d matrix estimation models, turning movement estimation models, and queuing models for designing turning storage lanes. Guidelines are also presented pointing to the trade-offs between regional models and site-impact models.
