CR Associates is supporting Cambridge Systematics in evaluating the Southern California Association of Governments (SCAG) Regional Active Transportation Database for potential database upgrades, as well as to develop enhanced flexibility in processing diverse data, such as feeds from automated counters or inputs from manual observation. This project includes a comprehensive review of existing data input processes, as well as a best-practices literature review, with interviews from key stakeholders familiar with the rapidly evolving landscape of bicycle and pedestrian count technology and database design. Additionally, final deliverables will include a regional automated counter siting framework, for use as jurisdictions throughout the SCAG region wish to add local counters to the regional network.
