Ramp Adaptive Metering Bottleneck Optimization (RAMBO) User's Manual (1232-31)

This report is the user's manual for a software package called "RAMBO" (Ramp Adaptive Metering Bottleneck Optimization). RAMBO is the end product of research conducted within SPR research project 1232 entitled "Urban Highway Operations Research and Implementation." It was developed by the Texas Transportation Institute for the Texas Department of Transportation as a practical ramp metering system, primarily for Texas applications. RAMBO consists of two complimentary programs RAMBO I and RAMBO II.|Rambo I employs interactive graphic screens to assist the traffic engineer in evaluating local ramp traffic conditions. It generates ramp metering plans based on the TxDOT ramp meter specification TXDOT-550-80-950-02 dated December 1991. It also generates Transition Point Patterns for each metering level.|RAMBO II is a system ramp metering package that evaluates ramp metering plans based on forecasted traffic conditions along an extended section of freeway containing up to 12 metered entrance ramps and 12 exit ramps.
