Speed Profile Analysis at the Speed Breakers at Some Locations in Dhaka City

Abstract

A speed breaker is placed perpendicular to a road to force drivers to reduce their speed. By regulating the speed of vehicles on local streets and accident-prone areas, they serve a significant role in enhancing safety. The reduction in speed is mostly determined by the length, height and kind of speed breakers. Commonly utilized types of speed breakers include speed bumps, speed humps, and artificial speed breakers. The purpose of this study is to determine the variation in speeds of different classes of vehicles at speed breakers road section of Manik Mia Avenue, Shyamoli Ring Road and West Raza Bazar in Dhaka. We provide a new approach for calculating the maximum permissible speed in curves that takes into account the three variables of the situation (distance, time, and speed) using the appropriate tools. The vehicle's dynamics are represented by a count and an average that incorporates a longitudinal top view and a side view-based speed analysis of speed breakers. The volume of traffic on the aforementioned highways was measured every 0-15 feet. Results found that during peak hours, the video was captured and the variation of speeds before and after 20 feet (Manik Mia Avenue), 6 feet (Shyamoli Ring Road), and 2 feet (West Rajabazar) from speed breakers was estimated at these sites. Both of the distances between us are identified by vehicle. The remaining rickshaw time at the Manik Mia avenue speed breaker is 8.94 km/h (2.02 seconds), while the remaining bike time is 15.36 km/h (1.12 sec). At an average of 1.12 seconds (11.96 kilometers per hour) per car, the West Rajabazar speed breaker was traversed. The average maximum speed per vehicle on Manik Mia Avenue is 12.25 km/h (1.51 seconds). We reviewed three-speed breakers in designated areas of Dhaka city and were able to determine the speed of the vehicles in front of the speed breaker while crossing the speed breaker and after crossing the speed breaker. Besides, we have been able to determine how many vehicles are moving every hour and what kind of vehicles are moving at Manik Mia Avenue carries 2,790 vehicles per hour, Shyamoli Ring Road in Dhaka sees an average of 2040 vehicle passes each hour, and West Razabazar there are 720 vehicular traffic movements each and every hour.
