This paper presents a discussion of a computer optimization program, which is used to optimize ramp metering and freeway flow by timing ramp signals to prevent excessive queuing on ramps while simultaneously minimizing delay on the freeway. The program can be used to design for a specified level of service and/or ramp queuing capacities based on the users constraints. This computer program was calibrated based on a specific section of the Milwaukee County Interstate Highway (IH) 94 freeway system. Data inputs to the program include freeway volumes, ramp volumes, distances between ramps, and ramp queuing capacities. The optimization program is a spreadsheet template so additional ramps can be easily added. Guidelines for application and further calibration with IVHS systems are discussed.
