Crossing time [T.sub.c] is determined by
pedestrian speed, which is influenced by the number of opposite pedestrians and crosswalk width.
The evaluation of the
pedestrian speed in homogeneous crowding conditions is an established experimental practice which leads to the so-called speed diagrams, that is, synthetic quantitative relations between the density of pedestrians and their average speed [31].
Also crossing
pedestrian speed in un-conflicted crossing condition is more than crossing time with conflicted of vehicles in both case signalized and un-signalized intersection.
In summary, the new multipedestrian detection system comprises several key modules: (1) a disparity-layered thresholding method that can be used to extract potential pedestrians layer by layer, (2) pedestrian detection with a 3-D convex curvature feature that can be used to window out pedestrians in each disparity layer, (3) continuous pedestrian association that correlates the same pedestrian in subsequent frames, and (4) estimation of
pedestrian speed and location.
Once the power unit is wound up to top legal speeds, it seems, quite unexpectedly, to muster an extra zip of energy which helps diminish the performance blips experienced at
pedestrian speed.

1: Get Assembly funding for speed cameras to be installed (this should be easy), and impose a
pedestrian speed limit of one mph - with a pounds 30 fine for people who dare to walk at the normal average speed elsewhere.
"It was run at a
pedestrian speed last year and I don't think it will
For example; if a wireless technology is able to support a data rate of 50 Kbps with
pedestrian speed, having a cost of 0.1 unit, short range coverage area (150 m) and RSS of -60 dBm, then the output of this wireless technology is calculated as 9.3 for a walker patient.
