Summary Information

Transit riders at Bellevue and Northgate Transit Centers in King County, Washington were provided with bus arrival/departure times, bay number, and expected actual departure times for all bus routes using each of the transfer centers. The Transit Watch system obtained actual departure times from an Automated Vehicle Location (AVL) system, and then presented the information on video monitors at each center.

The cost of the system was approximately $723,000 and annual O&M was approximately $180,000. The most significant costs were the development and labor costs. Approximately 12% of the capital cost and 25% of the O&M cost were shared with other Seattle Smart Trek Model Deployment Initiative (MMDI) projects.

The following data was presented in the report.
