Abstract:Phase I of the IMIS project examined the feasibility of implementing an Integrated Motorist Information System in a corridor located in New York (northern Long Island). The results are documented in report numbers FHWA-RD-77-47, 48 and 49. Under Phase II of IMIS (the present phase), the methodology for performing an IMIS feasibility study was generalized and put into "handbook" form to provide practicing traffic engineers with a step-by-step procedure for accomplishing such a study. Major topics included in the handbook are: criteria for IMIS Applicability, assembly of the necessary data base, selection and evaluation of candidate routes, equipment trade-offs, development of alternative preliminary designs, and system evaluation on a benefit/cost basis. Although the handbook is not intended as a detailed design guide, it addresses subjects requiring design related decisions, such as selection of communications media, alternate routes, diversion points, and ramp metering locations. As such, it should be of general interest to those concerned with freeway surveillance and control system design
