1 SAFETY OF OUR STREETS Assessing Safety Through Crash Data June 216 By analyzing crash data, the Des Moines Area Metropolitan Planning Organization (MPO) is able to help identify areas that tend to be most at risk for crashes. Using crash data provided by the Iowa Department of Transportation, the MPO pinpoints problem streets with higher crash densities and with more severe crashes. Common measures for crash data include Crashes per 1 Million Vehicle Miles Travelled (VMT) and total number of crashes. Safety Performance Rulemaking In April 216, the Federal Highway Administration (FHWA) released the final rulemaking for safety performance measures for the Highway Safety Improvement Program (HSIP). Included in the rulemaking are definitions of key terms, the applicability of the rule, and guidance on how to establish performance targets, determine if progress is achieved, and reporting targets for the HSIP. Rulemaking and the MPO Performance targets will be established by states beginning in August 217. The MPO will have 18 days after the state sets its targets to either: 1) Agree to support the State DOT target. 2) Establish target for each of the five performance measures specific to the MPO planning area. MPO target achievement will be monitored through the continued planning efforts of the MPO; including, long-range planning, project evaluation, and performance monitoring reports. Five Performance Measures* Number of Fatalities Rate of Fatalities per 1 million VMT Number of Serious Injuries Rate of Serious Injuries per 1 million VMT Number of Non-motorized Fatalities & Non-motorized Serious Injuries** *All measures based on a -year rolling average and based on the calendar year. **Combined total and must involve a motor vehicle.

Of all crash incidents: 9% Other/Not Reported 71% of vehicle crashes occurred during daylight. 1/3 of vehicle crashes happened during inclement weather conditions.

EJ areas are defined as concentrated areas of traditionally underserved populations, using the following population groups: Limited English Proficiency (LEP), non-white population, persons in poverty, car-less households, single heads of households with children, persons over 6, and persons with a disability.

8 MAKING STREETS SAFER Approaches for Streets In January 21, the U.S. Transportation Secretary Anthony Foxx challenged mayors across the county to improve the safety of all road users. The Mayors Challenge for Safer People and Safer Streets encourages a complete streets approach to street design to make roads safe for all users and to address barriers to safety. The following approaches are offered as best practices for designing safe streets. These approaches should be considered along with mix of traffic, adjacent land use, access management, and other elements of street design. Traffic Signal Timing Flashing Yellow Arrows Pedestrian Count-Down Timers Roadway Lighting Turn Lanes Improved signal timing can maintain traffic flow and prioritize pedestrian crossings Allow vehicles to turn after yeilding to on-coming traffic and pedestrians Pedestrian count-down timers make pedestrians aware of safe times to cross streets Roadway lighting can improve visibility along roadways between dusk and dawn Adding turn lanes can reduce the number of conflict points at intersections Travel Lane Width On-Street Parking Street Trees Building Placement Planted Medians Narrow travel lanes cause drivers to travel at slower speeds Narrows streets and slows traffic by creating friction Narrows the drivers visual field causing them to be more aware, drive slower, and provide protection to pedestrians Placing buildings closer to the road narrows visual fields, causing drivers to travel at slower speeds Narrows the drivers visual field causing them to be more aware and provides refuge for pedestrians Intersection Corners Designing smaller intersection corners slows turning vehicles and provides shorter crossings with better alignment for pedestrians Traffic Calming Use additional traffic calming to slow vehicles speeds th Street, Valley Junction Grand Avenue, Des Moines NW 62nd Street, Johnston
