ADMS (Archived Data Management System) archives real-time feeds from various systems (highways, arterials and public transport) of regional agencies, providing data on traffic flows, incidents and transit services. ADMS is a rich resource not only for system operations, management and planning, but also for analyzing the impact of system changes, from new infrastructure investments to fuel price fluctuations. Access to this extensive historical archive of real-time performance data from multimodal systems has provided a unique opportunity to demonstrate how "big data/" can be used for transportation planning and planning.
policy analysis. With funding from Metro, we are using ADMS to evaluate the impact of a major light rail investment in Los Angeles (the Expo Line) on the corridor-level performance of the multimodal transportation system, comparing corridor-level system performance before and after the opening of the railway. Our findings show a significant positive effect on public transport patronage, largely due to the existence of a latent demand for high-quality public transport.
