Transportation Concept Report Definition

The Transportation Concept Report (TCR) is a long-range planning document that describes the current characteristics of the transportation corridor and establishes a twenty-year planning concept. The TCR defines the California Department of
Transportation's (Caltrans) goal for the development of the transportation corridor in terms of level of service (LOS) and type of facilities, and broadly identifies the improvements needed to reach those goals.

Facility information (e.g., roadway widths, number of lanes) contained in the TCR represents a preliminary planning approach to identifying candidate improvements and to determining estimated costs. All information in TCR documents is subject to revision as conditions change and new information is obtained. Consequently, the nature and the size of identified improvements may change as they move through the project development stages. Final determinations are made at the time of project planning and design.
