Design Services

Hexagon Transportation Consultants, Inc., offers a wide range of traffic engineering design services, including conceptual roadway layout, traffic signal design, signing and striping plans, and traffic detour plans. Hexagon frequently prepares plan sets, but also provides support services for civil engineering firms with special traffic engineering-related design challenges. Our design work is prepared under the direction of both Registered Traffic Engineers and Registered Civil Engineers in the State of California.

Designs are prepared in conformance with the most current requirements of: the Federal Highway Administration manual on Uniform Traffic Control Devices, Americans With Disabilities Act, Caltrans Highway Design Manual, and the WATCH manual. We work directly with the presiding governmental agency on an informal basis to insure that plan submittals are as complete as possible and also are in conformance with local design requirements and specifications.  Design plans can be prepared in either Metric or English units in a variety of standard formats. We are proficient in both MicroStation and AutoCAD. Final design products typically include: mylar plan sets, electronic plan sets, plan specifications, and an engineer’s cost estimate.

Hexagon staff has successfully completed hundreds of design projects for many different public agencies and private clients. For this reason, our designs can be produced with minimal lead-time and with a high degree of accuracy and completeness.  Our collective experience includes design, management of contracts for design and construction, and the operation and maintenance of traffic signals in the field. This breadth of experience pays dividends to our clients by minimizing construction change orders, reducing energy demands and operating costs, and providing for convenient ongoing system maintenance.
