Crowding Conditions at the Station As measured for stations by station-to-station segments, crowding on trains in the morning rush hour between 8:00 and 9:00 a.m. is an indicator of service quality or level of comfort. It pertains to conditions at the station and does not reflect the quality of the rest of the transit trip. Three levels considered were determined by volume/capacity ratios: High crowding prevails when standees are in physical contact (V/C > 1.00); moderate crowding when some passengers remain standing (V/C .35 - 1.00); and low crowding when seats are available (V/C < .35). Where transit access is provided by stations that have high crowding ratios, the land value gradient declines rapidly with distance from the station. High crowding, which correlates strongly with moderate to heavy passenger volume, confers a higher relative benefit level than good on-time performance. For stations with high crowding ratios, the land value gradient is expressed as:

RATLSP_Ai Hc = 6.1252657 - 0.343086(WDST) - 0.223225(ADW) ' (.0003) (.0173) + 0.136292(WDP) - 0.431209(POVERTY) (.1832) (.1201) + 0.156470(EMP) - 0.523280(MIDTM) (.1846) (.0146) - 0.786779(DNTM) + 0.142285(CRIME’rape) (.0001) (.2871) r2 = .1977

For stations with moderate crowding ratios, the lower order of benefit conferred by access to the station is in keeping with the vacant land baseline or the sloping land value relationship around stations of low to moderate service frequency. For these stations, the declining land value gradients are expressed as:

RATLSP_Ai = 6.148581 - 0.125631 (WDST) + 0.026026 (ADW) ' (.0061) (.5500) - 0.109934(WDP) - 0.619193(POVERTY) (.0099) (.0001) + 0.191274(EMP) - 1.148254(MIDTM) (.0013) (.0001) + 0.028467(DNTM) - 0.182289(CRIME'rape) (.7964) (.0001) r2 = .1532
