There may be alternative solutions to the problem at your intersection. Trees or bushes can be trimmed or parking restrictions can be installed near the intersection to help increase visibility. It is the owner's responsibility to trim any privately-owned shrubbery obstructing any public signs. Police enforcement can improve safety. Installation of Interactive Radar Speed Display signs may prove to be an effective solution too.
Generally, the best ways to insure traffic safety are to educate motorists and pedestrians to be cautious at all times and to enforce traffic laws.
