Corridor Planning Process Guide

Cover Page


Corridor Planning is a multimodal transportation planning approach that recognizes that transportation needs are based on the complex geographic, demographic, economic, and social characteristics of communities. These locations are tied together by a complex system of streets, roads, highways, trails, paths, rail lines, bus corridors, and other elements that affect the convenience, safety, and accessibility of transportation choices. Increasingly, technologies such as real-time, web- and mobile-enabled trip planning and ride-sourcing services are changing how people travel. Soon, automated and connected vehicles, and unmanned aerial systems (e.g., drones) are expected to be part of our transportation landscape and will transform the way that people and freight are transported.



This Guidebook provides direction to Caltrans staff regarding the transportation planning process, but it can be used by other agencies. It does not focus on a specific fund source but should consider all available funding sources. It is basically a comprehensive analysis of a transportation corridor and should address multiple needs. The Guidebook was developed in collaboration with the California Transportation Commission’s (CTC) Comprehensive Multimodal Corridor Plan Guidelines approved in December of 2018. The CTC’s Guidelines were developed to provide guidance to eligible program applicants regarding the statutory requirements for comprehensive corridor plans utilized by agencies to apply for funding through the Solutions to Congested Corridors Program. In other words, the CTC Guidelines provide direction for one funding program and the Caltrans Guidebook provides guidance for corridor planning irrespective of fund source.
