Development of Pedestrian Crossing Facility Warrants for Urban Midblock Crosswalks Based on Vehicular Delay

Critical Analysis of Road Side Friction on an Urban Arterial Road

“…In [4], a pedestrian crossing traffic model was proposed for a city street. The volumes of traffic, speeds, and numbers of people crossing in and out of traffic are the inputs to the model (1) for calculating the average speed of a certain vehicle type:…”

“…where v i is the speed of a particular vehicle (m/s), v j is the speed of various types of vehicle, a o is the regression coefficient for the free flow speed of the j th type vehicle, a ' i and a ' k are regression coefficients for the impact of density of a particular vehicle type and pedestrians on the free flow speed of the j-th type vehicle, respectively, n i is the number of vehicles (v/s), and n ped /v j is the pedestrian-vehicle interaction factor (m/s). Speed Reduction [1] 100 peds/h 2.5% [3] 100 peds/h 7.23 km/h [4] 100 peds/h 4.21%. [5] 100 peds/h 3.52%.…”

“…Reference Ped-crossing volume Capacity reduction [4] Upto 200 ped/h No impact [20] 200 ped/h Negligible [4] 1550 ped/h 32% [1] 1550 ped/h 9% [6] 1550 ped/h 20% [7] 1550 ped/h 23% [8] 1550 ped/h 25% [12] 1550 ped/h 19% [15] 1550 ped/h 27% [17] 1550 ped/h 30-37% [18] 1550 ped/h 32% [19] 1550 ped/h 32% [20] 1550 ped/h 33% [21] 1550 ped/h 14% [24] 1550 ped/h 11.05-60.73%…”

“…Even a very small number of vehicles might result in significant congestion if they are parked disruptively for an extended time. Additionally, even when every available spot is almost full, a sizable percentage of vehicles still prefer onstreet parking, and instead of paying for off-street parking, they would rather continue looking until a spot opened up [4]. When these park-hunting vehicles are present in large numbers, they can significantly reduce both the capacity of urban roadways and stream transportation.…”
