The Bureau of Traffic Operations, New York City Department of Transportation (NYCDOT) utilizes for various types of studies and capacity analyses, the 1985 Highway Capacity Methodology and links the results from the analyses with the TRAF-NETSIM traffic simulation model. This is presently done by using the HCM/CINEMA computer program (a registered trademark of KLD Associates Inc. and Polytechnic University, New York). This paper describes how the program was used in a real 'case study' by the Bureau of Traffic Operations to evaluate traffic conditions prior to implementing any changes to the local street system. The program has been a valuable tool for the traffic engineers, assisting them in implementing detour alternatives and also recommending the appropriate modifications in the traffic signal cycle lengths, sequences and splits.
