COMPARISON OF DELAY AND ACCIDENTS ON THREE ROADWAY ACCESS DESIGNS IN SPRINGFIELD

A comparison was made of three urban arterial roadways in Springfield, Missouri, each having similar lengths, posted speed limits, volumes, and abutting land uses but different levels of access control. The three segments were close to each other. The street with the highest level of access management (a non-traversable median and a much greater access spacing) was found to have both a lower crash rate and less delay than the other two roadway sections with a center turn lane. A comparison of the two center turn lane roadways found that an increase in driveway spacing did not produce faster travel times or a lower crash rate.
