The vehicle weighs no more than 40 pounds and moves at pedestrian speed
, according to the Starship (https://www.starship.xyz/for-businesses/) site .
Crossing time [T.sub.c] is determined by pedestrian speed
, which is influenced by the number of opposite pedestrians and crosswalk width.
Main parameters Numerical Simulation time (s) 600 Lane number 6 Lane width (m) 3.5 Potential capacity (pcu/h) 1000 Design speed (km/h) 40 Pedestrian speed
(m/s) 1.3 Crossing number (person/h) 400,600,800,1000,1200 Table 9: Road crossing control under the condition of pedestrian crossing traffic capacity.
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 .
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
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.
