You are correct, my response is the text book answer. Often the 85th percentile is rounded to the nearest speed that matches the fixed limits. Special speed zones, schools, definitely need to exist for obvious safety reasons.
- reitanqild 10y agoThanks for chiming in. If you still look at this thread: I guess you live in the US? (Around here it does not seem to work this way.)
- takk309 10y agoYes, I do live in the US. Even here there is a lot of variation on how speed limits are set. A good example happened near my home recently. A road that connects a small town (population 8,000) to a larger town (population 40,000) was the subject of quite a lot of debate. The road is a rural two lane roadway that sees about 10,000 vehicles per day. Speed studies were performed by three different groups (the small city, the large city, and the State Department of Transportation). Each of the groups determined their own speed limit recommendation, each was different. Ultimately, the State had final say on the matter and split the difference between the three recommendations. The State had originally wanted the highest speed limit of the three. The two towns wanted lower speed limits citing safety concerns and a desire to force alternate routes that would take traffic through areas with better infrastructure for the traffic load.
