Posted by JerBear on Fri Mar 11 09:22:24 2016, in response to Re: Summary and Video of November 2015 SBS meeting in Woodhaven, posted by R30A on Thu Mar 10 11:11:32 2016. From the NYC Street Design Manual:"Motor vehicle level of service (LOS) is a major consideration in developing a project design because of the importance of maintaining traffic flow to the city’s economy. DOT therefore treats LOS as a priority." And later, under Table 1B (which itself lists average delay of vehicles at signalized and unsignalized intersections) : "Traffic engineers and planners use LOS analysis at signalized and unsignalized intersections to measure a project’s impact on vehicular traffic. They analyze and compare intersections under existing and “post-build” conditions. Under the CEQR Manual, project designs that worsen LOS to below mid-D in a model require a full environmental impact statement and often mitigation." No mention of limiting the use of the measure to highways. In fact, in the definitions in the glossery (j/k): "LOS. A methodology for measuring traffic flow based on traveler delay and congestion, defined in the Highway Capacity Manual (HCM). Gradesfrom A to F are used, from free flowto traffic jam conditions. Historically used primarily for motor vehicle traffic, LOS methodologies have also been devised for pedestrian, bicyclist,and transit operations." |
