The Highway Design Manual, originally issued in July 1972 and March 1973, has been revised over 70 times. Old versions are available through the link to the HDM Revision Log. Context: The HDM is the primary source of guidance for detailed highway design. It is also frequently referred to in the scoping stage and preliminary design phase and CalTrans Highway Design Manual Stopping Sight Distance based on design speed.
2. For local streets, the minimum acceptable vertical curve is ten feet (3 m) of curve for each one percent difference in grade. 3. Vertical curves leading into intersections shall be designed such that the grade immediately Caltrans Highway Design Manual, Bicycle Transportation Design: Chapter 1000 Manual on Uniform Traffic Control Devices, Traffic Control for Bicycle Facilities: Part 9 Caltrans Local Assistance Project Development Procedures Manual, Chapter 31 Highway Design Manual, Chapter 1000, Bicycle Transportation Design The needs of nonmotorized transportation are an essential part of all highway projects.
Mobility for all travel modes is recognized as an integral element of the transportation system. Source: Caltran Highway Design Manual, Chapter 870 These supersede the previous Caltrans Riprap Sizes. Caltrans requires the use of these new RSP gradations starting August 1st, 2016 in new projects and those not yet at 30 percent PS& E stage. The engineering design of flexible pavement structures is not an exact science. It is not possible to formulate one set of design criteria that could meet the requirements of every road everywhere.
Traffic conditions, climate, geology, materials, construction, and economics are variables that demand the fullest application of professional Caltrans Highway Design Manual Chapter 300 HIGHWAY DESIGN MANUAL. 1001 Chapter 2 of the California MUTCD, which include 300 feet of a median opening unless the access opening is directly. 02 Signs (see Section 2B. 26), Caltrans Manuals.
