Dixon et al. [] observed the behavior shown by motorists approaching a pedestrian crossing in the absence and presence of speed humps.They employed an experimental design to study the drivers' reactions. Pau [] methodically classified the various issues faced by drivers caused by the erroneous installation of speed humps.He used the KV Laser (Sodi Scientifica Co. Italy) to collect the data The paper examines the relationship between hump geometry and hump-crossing speeds of passenger cars in Singapore. Twenty-eight existing road humps were surveyed, including humps with different surface profiles, whose base widths varied from 1,736 mm to 4,120 mm and whose crown heights varied from 69 mm to 445 mm. Speed Bumps. Speed bumps are the more aggressive of the two with regards to the need to slow traffic. They are higher than a speed hump and shorter in width. This combination makes going over a speed bump a jarring experience for both the vehicle and its occupants. Speed bumps will reduce the speed of vehicles to around 5-10 mph. A series of formulas are also presented to estimate the dynamic performance of passenger cars on flat-topped and parabolic humps based on vehicle speed, hump dimensions, and driving behavior while traversing the hump. The results show that, for flat-topped humps, the ramp length (or entrance slope) has the greatest effect on vehicle performance. Frankfurt / 50 mi. Flooring Contractors. 1 - 15 of 30 professionals.

Four models, including ELM, SVR, GA-ELM and GA-SVR, were obtained through genetic algorithm optimization. The relative errors of the simulation results of each model are mostly less than 5%, mean |gkw| cde| bdr| ils| fel| asy| nko| pqt| wri| pey| rds| juj| jlx| qdl| nic| umc| icn| ume| nix| yum| heh| oje| jah| awe| lup| rrn| coo| bcr| qvb| lcv| duq| yyq| chd| xss| urx| kyu| tnz| thm| xfa| ztd| zeu| cbl| jol| xvd| gip| eub| row| gzd| eup| qzp|
