St Paul's Speed Limit Evaluation Report, referenced numerous studies that support a reduced <br />speed limit to reduce crashes and reduce severity of injuries. <br />Some of the key findings include reduction of the stopping distance with lower speeds, which <br />helps reduce the amount of crashes. Additionally, if a crash does occur, the risk for a pedestrian <br />being severely injured or killed is significantly reduced if the speed is 20 mph verse 30 mph. <br />These findings are illustrated in the graphics below: <br />40 mph <br />35 mph <br />30 mph <br />25 mph <br />20 mph <br />15 mph <br />Stopping Sight Distance by Travel Speed <br />0' 50' 100' 150' 200' 250' 300' 350' <br />Data Source: American Association of State Highway and Transportation Officials (AASHTO).
