What is the key to effective speed management?

The 'golden rule' for speed management aimed at maximising road safety and the corollary of research in the area is the 85th percentile rule. This states that speed limits should be set at the 85th percentile for the section of road. Setting speed limits lower than the 85th percentile results in more crashes and less compliance. In other words more deaths and more speeding tickets.

After exposure to continual propaganda which implies that speed limits are set by God and almost all of us are dangerous drivers who need to be re-educated to see the error of our minor speed limit breaching ways it may be surprising to read that speed limits should be set in accordance with the speeds that most motorists already choose to drive or ride. However such an approach not only advances democratic ideals but also promotes road safety.

If questions such as "what happens if motorists speed up when limits are raised?" come to mind then stop assuming that something that important wouldn't have been researched. Our knowledge of these things is not as primitive as authorities would have you believe. Reading the arguments on the page from whence you came here should answer your question. Dig in!
