But do you use just the peak hour or the entire peak which may be three or four hours?You shoukd survey the entire peak, but that doesn't mean you ignore weekends where the peak may actually occur on a Saturday at noon at one or more intersections. As Brian said, "All of this info can be found in standard Transportation planning manuals from ITE and also in the NYC CEQR Manual, Chapter 16: Transportation" (and as I've said before, it's appalling that you pass yourself off as a veteran transportation planner yet don't know such basic concepts). From the CEQR Technical Manual, Section 332 - Determination of Peak Periods: "Generally, the same peak period is used for all transportation analyses. Each peak period is typically two to four hours. However, the actual analysis is performed for a shorter time period within the peak period, such as a peak hour or peak 15 minutes" And from Section 342.1 - Determination of the Peak Hour for Analysis Purposes: "For most proposed projects, the peak analysis hours are the same as the peak travel hours already occurring on study area streets, i.e., the specific one hour within the morning home-to-work and the late afternoon/early evening return trip rush hour... To determine prevailing peak hours in the study area, the source of existing traffic volumes may either be available through 24-hour Automatic Traffic Recorder (ATR) machine counts or new counts obtained from installed ATR machines." |
