Transportation System Plan

TSP Cover Page

The Transportation System Plan (TSP) defines the future of the County’s transportation system. The plan reflects community aspirations and takes into account projected population and employment growth over the next 20 years. The TSP outlines policies and strategies to meet existing and future travel needs for:

  • Automobile users
  • Pedestrians
  • Cyclists
  • Transit users
  • Freight vehicles

The TSP provides guidance on how to build, operate and maintain the County’s major roadway network, while addressing elements of the larger transportation system including multiuse trails, state highways and railroads maintained by other agencies.
