California Department of Transportation
 

Division of Design

The Division of Design provides the procedures, policy, standards, guidance, technical assistance, and training needed to facilitate California transportation improvements and system integrity. The Design Program innovates design solutions by:

  • Seeking out and synthesizing information and customer feedback.
  • Causing the adoption of "best practices" and design information to promote safety, statewide consistency, efficiency and quality.
  • Assisting our customers in the application of design information and practices to facilitate the resolution of project development issues.

Whats New:

  • To reaffirm the Caltrans commitment to providing flexibility while maintaining the safety and integrity of the state highway system, and local streets and roads under the jurisdiction of cities and counties, the Department recently released a memorandum titled "Design Flexibility in Multimodal Design" dated April 10, 2014. The memorandum highlights the flexibility provided in existing Caltrans guidance, positive steps already taken in underscoring the importance of multimodal design, and recognizes the value of other guidance in supporting planning and design decisions made by state and local decision makers statewide.

    The Highway Design Manual (HDM) has been revised with the 6th Edition HDM change 03/07/14. Changes include new intersection control guidance in coordination with the recently released Division of Traffic Operations Intersection Control Evaluation (ICE) policy directive. These changes supersede Design Information Bulletin (DIB) Number 80: Roundabouts. Also included are extensive highway drainage design guidance revisions that reflect current nomenclature and correction/update of references to text, tables, figures and website addresses.

  • Main Street, California - A Guide for Improving Community and Transportation Vitality - California State Highways that also function as main streets through communities are challenged with balancing the public’s need for roadways that provide local, regional and statewide connections, with local needs for a vibrant community street. Just as mobility is essential to California’s economic and civic vitality, the planning, design and operation of main streets is tied to the prosperity of local communities. Well conceived main streets function efficiently as multimodal transportation facilities, and are important civic spaces that support vibrant community life and ecological health. Prudent investments to provide multimodal travel options are a crucial strategy for reducing greenhouse gas emissions and other environmental impacts associated with single occupancy driving habits. 
  • Incorporating principles of livability and sustainability into main street projects can help balance the need for an efficient multimodal
    transportation facility with local needs for a main street that functions as the heart of the community. Some design solutions highlighted in Main Street will be familiar or slight variations of traditional strategies, while others will entail a new and broader vision of how main streets can benefit travelers and the local community.

    Caltrans is committed to working with local communities toward a more collaborative, multimodal and productive State-local approach to shared assets.
