Transportation access management is defined as systematic control of the design, spacing, operation, and locations of street connections, interchanges, driveways, and median openings on the roadway with the purpose of providing vehicle access while preserving the efficiency and safety of the entire transportation system. Access management is a proven method for maintaining and improving roadway capacity; traffic flow; and the safety of traffic, pedestrians, and bicyclists on rural and urban highways and streets. No locally calibrated tool existed that captures the complexity of the current and future public benefits of proposed access management for estimating the financial and other benefits and comparing them with the associated financial costs. Therefore, this study had three primary objectives: (1) develop and validate benefits estimation methodology, (2) compile and derive supporting data for benefits estimation methodology, and (3) develop a software tool for benefits estimation. The result is a simple, straightforward benefits estimation methodology focused on benefits related to traffic operations, traffic safety, environmental impacts, and project costs. The methodology is facilitated by the two spreadsheet software tools that implement the benefits estimation and the calculation of traffic safety benefits, with Synchro/SimTraffic utilized for estimation of traffic operations and environmental impacts.
