Request On Twitter : I have a request. If you need to repaint lanes on 280 near Palo Alto, please don't do it during morning rush hour. Thanks.

Caltrans tries to avoid doing any work during commune peak hours except for emergency circumstances. In this particular case we had to schedule emergency stripping on fading lines and the process to apply these stripes requires warmer temperatures.

Due to the fact that the stripping process requires warmer temperatures Caltrans had to schedule this process during the day time.

Does Caltrans have a formula for determining how smooth or rough to make a road surface?

Caltrans does not use a formula, but we use an equipment that measures the coefficient of friction.  Here is a weblink for California Test Method 342 on measuring a roadway’s coefficient of friction.

Does Caltrans design road surfaces to control how fast cars can travel on them?

No, we do not design roadway surface to control how fast cars can travel. What controls how fast cars can travel is the roadway’s design alignment such as the roadway’s radius of curvature and how much the cross slope of the curve is superelevated (banked).  Keep in mind that wet weather and sight distance also control how fast vehicles can travel.  We post speed limit signs (white signs) for speed enforcement and warning speed and/or condition signs (yellow signs) to alert motorists in advance.
