mzgloves20 said:I don't know about where you are, but here in PA, speeds limits are set up by population, number of interchanges and houses along a roadway or highway and by engineering studies ( critical speed calculations based on roadway design ) by the department of transportation. Only the very small streets (residential) speed limits can be set by the towns or boroughs or cities, NOT by the police department. The towns government has to approve the speed-limits and citizens can come to the meetings and address the council people with their opinions. Then it has to be posted according to state law. ( # of signs so many feet apart...lalala...)
The state of Texas lowered freeway speed limits in the DFW area under pressure from the EPA and even the Dallas police will admit that one of the problems with speeding on the freeways is that the limits are too low. In Richardson, there is not a single street that has a speed limit above 40. Even on roads with light traffic and that have 3 lanes each side and seperated by a median, still have a limit of 40. They do not use the 85th percentile (the speed that 85% of the drivers will instinctively drive at or slightly under even if there are no posted limits) to set speeds, but one that is unreasonably low so they can write more tickets. Colleyville is the same way. Other than Highway 26, all speeds are 30 or 35.
I know police officers in Plano (right next to Richardson) who will tell you the reason Richardson has such low limits is for revenue, not safety. Plano has higher speed limits on the same roads-once you cross into the Plano city limits, the speed on Jupiter road rises from 40 to 45 and the accident rates are the same.
Where I live in Arlington, the primary focus is on I-30, SH 360 and Green Oaks, which loops around the city. There is very little enforcement around the Ballpark In Arlington and Six Flags/Hurricane Harbor, especially during tourist season since they don't want to get a reputation as a speed trap. The city make so much money off the Rangers and the theme parks that they don't need to depend on traffic fines to fill the city's coffers.
