This paper presents New York State Department of Transportation's experience with the calibration and testing of a simplified procedure for estimating urban traffic at the project level. The procedure was developed by COMSIS Corporation under contract to FHWA, and NYSDOT, as a sub-contractor, was responsible for testing the procedure and assessing its effectiveness and accuracy. The procedure estimates a traffic growth factor based on the growth of trip production and attraction variables. It uses a simplified gravity model formulation and a 24-zone structure centered on the project site. Six case study sites were selected to test the procedure.
