Empirical Studies on Traffic Flow in Inclement Weather
Figure 5.11. This figure presents three plots of free-flow speed (uf) WAF, capacity (qc) WAF and speed-at-capacity (uc) WAF versus rain intensity for Baltimore, Twin Cities, and Seattle and presents the following values: For u subscript f, c subscript 3, c subscript 2, and c subscript 1 values for Baltimore are 0.000, -0.033, and 0.963, respectively. For u subscript f, c subscript 3, c subscript 2, and c subscript 1 values for Seattle are 0.032, -0.086, and 0.975, respectively. For u subscript f, c subscript 3, c subscript 2, and c subscript 1 values for Twin Cities are 0.000, -0.027, and 0.980, respectively. For u subscript c, c subscript 3, c subscript 2, and c subscript 1 values for Baltimore are 0.000, -0.031, and 0.901, respectively. For u subscript c, c subscript 3, c subscript 2, and c subscript 1 values for Seattle are 0.030, -0.080, and 0.917, respectively. For u subscript c, c subscript 3, c subscript 2, and c subscript 1 values for Twin Cities are 0.000, -0.000, and 0.896, respectively. For q subscript c, c subscript 3, c subscript 2, and c subscript 1 values for Baltimore are 0.000, 0.000, and 0.892, respectively. For q subscript c, c subscript 3, c subscript 2, and c subscript 1 values for Seattle are 0.000, 0.000, and 0.896, respectively. For q subscript c, c subscript 3, c subscript 2, and c subscript 1 values for Twin Cities are 0.000, 0.000, and 0.889, respectively.
