Traffic Control Devices Handbook
Source: Institute of Transportation Engineers
The Traffic Control Devices Handbook (TCDH) was created to augment the MUTCD as adopted nationally by the Federal Highway Administration. While the MUTCD outlines the design and application of traffic control devices on public roadways in the United States, criteria and data to make decisions on the use of a device and its application are not always fully covered in the MUTCD.
The Handbook can be ordered through the Institute of Transportation Engineers (ITE) online bookstore at the link below.
