Temporary Traffic Control (TTC) references

The City of Sacramento is not taking the failures of its construction zone signing and maintenance seriously. I have forwarded a number of issues to the city, both via email and via the 311 service. Nothing seems to have come of any of this. I have not seen a single location corrected. The 311 requests are being closed without being corrected. It is not clear to me whether the city staff are incompetent, or simply don’t care, but I’m going to list some resources I’ve found useful. These may be useful to readers, so that you can recognize failures and report them as well.

The Manual of Uniform Traffic Control Devices (MUTCD) addresses construction zones in Part 6: Temporary Traffic Control Devices. California has its own version, similar but not identical, the CA-MUTCD Part 6. Don’t misunderstand me, the MUTCD/CA-MUTCD is very weak on pedestrian and bicyclist accommodation. If you randomly threw a dart at the manual, 999 times out of 1000, you would see text or signs or diagrams that assume that pedestrians and bicyclists don’t exist. Nevertheless, the manual has the force of law, for any agency that uses federal funding, and it is what most agencies use as the gospel.

Note that the MUTCD prohibits the use of tape, rope, or plastic chain strung between devices because they are not detectable and do not comply with the design standards in the ADAAG; therefore, they may not be used as a control for pedestrian movements (MUTCD 6D.01).
