... IV-1 EXHIBIT IV-1 Strategies Classified by Relative Cost and Time Necessary for Implementation Relative Cost to Implement and Operate Strategy Timeframe: Short (less than 1 year) Low A1 Set speed limits that account for roadway design, traffic, and environment A2 Implement variable speed limits A3 Implement differential speed limits for heavy vehicles if appropriate B2 Increase public awareness of potential penalties for speeding B3 Increase public awareness of risks of not wearing seatbelts B4 Implement neighborhood speed watch/traffic management programs C3 Increase penalties for repeat and excessive speeding offenders C4 Strengthen the adjudication of speeding citations to enhance the deterrent effect of fines

Low Moderate Moderate to High High SECTION IV -- INDEX OF STRATEGIES BY IMPLEMENTATION TIMEFRAME AND RELATIVE COST IV-2 C5 Increase fines in special areas D1 Improve speed limit signage D2 Implement active speed warning signs E4 Provide adequate change + clearance intervals at signalized intersections E5 Operate traffic signals appropriately for intersections and corridors (signal progression) B1 Increase public awareness of the risks of driving at unsafe speeds B5 Implement Safe Community programs C1 Use targeted conventional speed enforcement programs at locations known to have speeding-related crashes D3 Use in-pavement measures to communicate the need to reduce speeds E8 Install lighting at high-speed intersections C2 Implement automated speed enforcement D4 Implement variable message signs E3 Provide appropriate intersection design for speed of roadway E6 Provide adequate sight distance for expected speeds E7 Implement protected-only signal phasing for left turns at high-speed signalized intersections E9 Reduce speeds and/or volumes on both neighborhood and downtown streets with the use of traffic calming and other related countermeasures E2 Effect safe speed transitions through design elements and on approaches to lower speed areas E1 Use combinations of geometric elements to control speeds EXHIBIT IV-1 (Continued)
