SMALL AREA TRAFFIC ANALYSIS USING THE LATM PACKAGE

The evaluation of urban traffic and environmental systems management may often require studies of traffic movements and demands in small parts of an urban area, and may also involve comparisons between alternative proposals. Modelling procedures could be of great use in these studies. However, until recently there has been a dearth of suitable models for such studies. This paper describes the development, from an experimental micro-area traffic assignment procedure, of a model package suitable for small-area, short-duration studies. The package is known as latm (for local area traffic model). It can distinguish between alternative intersection control and traffic management schemes, and has great flexibility. Model outputs can be obtained at a number of levels of refinement, depending upon available input data and the requirements of the user. The model may be used to simulate network effects of changes in traffic control policies and travel demands in a small area within a user-specified time period. This paper discusses the data requirements of the package, and the corresponding model outputs, model parameter determination, and possible applications of the package. Three applications of the package are described for problems concerning the generation and distribution of traffic in small areas. (A) /TRRL/
