There is nothing like a near miss or collision to focus your mind on road safety. I often hear from people hoping to enlist my help in solving their issue. Requests have ranged from posting lower speed limits to constructing left turn lanes recently. Most people have already tried something on their own and are frustrated with what they see as the authorities not wanting to apply what they see as the solution.
We live in an age of access to information. In fact, there is so much of it on the internet that one has to be careful that they are reading reliable information instead of rants, rumours and opposing points of view. However, by doing some research with respected sources, you can create a logical, comprehensive identification of the problem and useful solutions to present to the authorities to deal with your issue.
