Management Strategy Effectiveness <br />As stated earlier, traffic management strategies are not universally applicable or effective at <br />solving all problems. The Institute of Transportation Engineers has collected data on the <br />effectiveness of traffic management strategies implemented throughout the United States. <br />Table2provides a summary of this data and can be useful in the selection of appropriate <br />trafficmanagement strategy to implement. Along with the information provided in Table 2 <br />oneffectiveness, the following are some other effectiveness considerations: <br />Traffic control devices, by themselves, are almost never effective at reducing traffic <br />volumes or vehicle speeds. <br />Enforcement can be effective if applied regularly and over an extended period of <br />time. <br />In most cases, enforcement will result in local citizensbeing ticketed. <br />Roadway adjustments (narrowing) have proven to be moderately effective but at high <br />implementation costs. <br />Vertical elements (primarily speed humps/bumps) have proven to be moderately <br />effective but neighborhood acceptance has been mixed. <br />The combination of enforcement plus other strategies has proven to be the most <br />effectiveapproach. <br />The following terms are used in Table 2: <br />Poss-it is possible that this strategy will affect the problem. <br />Yes-it is expected that this strategy will affect the problem. <br />No-this strategy will have no effect on this problem. <br />8 City Council Review Draft- 4/06/12 <br /> <br />
