AutoCad™ Dynamic Temporary Traffic Control Blocks will help any industry that needs to perform work on any street in the US. Anyone new to TTC (temporary traffic control) or existing drafters can produce more uniform, faster and easier plans. With the use of dynamic blocks and AutoCad’s Tools Palette, plan creation is just a drag and drop away. The typical street and street characteristics blocks are much faster than drawing from scratch. (See the Sample_dwgs.pdf for examples of plans created with Dynamic Traffic Control Blocks). The TTC (temporary traffic control) sign symbol blocks were created from the Manual for Uniform Traffic Control Devices (MUTCD) 2003 edition which is the current edition as of 12/27/07 developed by the Federal Highway Administration. California signs are from the MUTCD California 9/27/06 revised edition.
