Table 5-3 Continued Summary of Intersection Level of Service Improvement Strategies and Policy Criteria STRATEGIES 1-Hour LOS D Sta ndard 1 Hour LOS E Sta ndard 2nd Hour LOS D Sta ndard Safety Intersections w ould be less congested and generally safer. Drivers w ould be less likely to run red lights. With potentially congestion than the LO S D standard, more red light running could occur. greater delay and Potentially greater delay and congestion than the other standards . More red light running could occur, w ith potentially negative effects on safety . Air quality implications LOS D standard could result in less delay and relatively lower carbon monoxide emissions at major intersections. Possibly higher PM10 emissions. LOS E standard could resu lt in greater delay and relatively higher carbon monoxide emissions at major intersections. Possibly lower PM10 emissions. The tw o-hour standard could allow LOS E or LOS F during the highest hour, potentially resulting in the highest carbon monoxide emissions of the three strategies. Potential to reduce local traffic impacts o n I-5 Improvements to arterial congestion points could reduce local traffic using I-5, if coupled with greater north/south connectivity . With few er arterial improvements compared to LOS D standard, less reduction of local traffic on I-5 w ould be expected. Similar to the LOS E standard, depending on the number of locations operating at LOS E or F during the second highest hour, and on the peaking characteristics at those intersections. Potential to reduce reliance on the automobile Least effective in reducing reliance on the automobile. Greater allow able congestion in theory would promote greater us e of alternatives to single-occupant automobile; how ever, the majority of intersections w ould continue to operate acceptably without mitigation. Transit is negatively affected by congestion. Similar to the LOS E standard, depending on the number of locations operating at LOS E or F during the second highest hour, and on the peaking characteristics at those intersections. Cost Approximately $3 to $ 5 million higher than either of the other tw o alternatives. Lower cost than the LOS D standard due to fewer mitigation requirements. Similar to LOS E standard.
