Spot Speed Analysis of Vehicular Traffic and Travel Time in Birulia to Dhour Corridor

Abstract

Dhaka, Bangladesh's capital city is the epicenter of all governmental, economic and social activities, but traffic congestion and delays are prevalent issues. The primary goal of this study is to comprehend the current state of spot speed and journey time of vehicular traffic along a corridor that spans from Birulia to Dhour which is almost one kilometer in length. To analyze spot speed, we manually collected travel time data using a smartphone's stopwatch in 3 locations ( Birulia, NDE gate, Panchabati) along corridor. And the result shows that the highest spot speed measured at 40 feet segment in Burilia was 32.16 km/hr. where as the average spot speed was 34.81 km/hr of total three area. NDE gate are maximum speed 42.86 km/hr was observed in morning time where at minimum speed 33.45 km/hr was in the observed noon at a distance of 50 feet. Also we are found that Punchaboti maximum speed 37.36 km/hr in morning time and minimum speed 33.03 km/hr was in afternoon at a distance of 55 feet. In addition to spot speed analysis, we also measured the travel time along this corridor. Our data showed that the average travel time from Birulia to Punchaboti was 116.74 sec with the fastest travel time recorded at 80.24 sec and the slowest at 157.17sec. The highest speeds were observed during off-peak hours. On the other hand, travel time data showed that the average time taken to travel along the corridor ranged from 116.74 sec, depending on the distance and traffic conditions.
