APPLICATION OF FREEWAY SIMULATION MODELS TO URBAN CORRIDORS. VOLUME VIII: EXECUTIVE SUMMARY

This report is one of eight documents prepared under a U.S. Department of Transportation, Federal Highway Administration (FHWA) contract entitled "Analysis of Complex Congested Corridor Locations". The purpose of the project was to evaluate the effectiveness and ease of use of three freeway simulation models and the freeway analysis procedures described in the 1985 Highway Capacity Manual (HCM) by applying them to a series of real world situations. The three simulation models tested were: FREFLO - a macroscopic model developed and supported by the FHWA as part of the TRAF modeling system; FREQ - a second macroscopic model developed and supported by the Institute of Transportation Studies, University of California at Berkeley; and FRESIM - a microscopic model developed and supported by the FHWA, representing an extension of an earlier FHWA model known as INTRAS. Each of these models, together with the computerized version of the 1985 HCM procedures, known as the Highway Capacity Software (HCS), was applied to each of five case studies. Each case study location was experiencing severe operating problems. The models were used to evaluate these problems, and to test a range of possible remedial actions. This report is an executive summary of the project. The other volumes in the series are: FHWA-RD-92-103 Volume I: Final Report; FHWA-RD-92-104 Volume II: Technical Report; FHWA-RD-92-105 Volume III: Alternative Analysis Report, I-94 Eastbound between U.S.H. 45 (Zoo Interchange) and I-43 (CBD Terminus) in Milwaukee, Wisconsin; FHWA-RD-92-106 Volume IV: Incident Management Alternative Analysis Report for the George Washington Bridge and Cross Bronx Expressway Eastbound, New York/New Jersey; FHWA-RD-92-107 Volume V: Alternative Analysis Report, I-494 Eastbound between Prairie Center Drive and T.H. 5 in Minneapolis, Minnesota; FHWA-RD-92-108 Volume VI: Alternative Analysis Report, I-70 and I-71 Northbound Immediately to the South and East of Downtown Columbus, Ohio; and FHWA-RD-92-109 Volume VII: Alternative Analysis Report, I-5 Southbound, between S.R. 900 and S.R. 18 in Seattle, Washington.
