Speed Management and Safe Crossing on Dhaka-Sylhet Highway (N2) in Bangladesh

The detailed speed difference is being presented in the following tables for each locations in
Table 6.1, 6.2, 6.3 respectively which are showing good example of speed calming without
hampering the major function of the road
Table 6.1: Nilkuthi: before <strong>and</strong> after speed data
Nilkuthi Baseline <strong>Speed</strong> (km/h) End line(km/h) Dif ference(km/h)
Bus 68.7 54.6 14.0
Truck 53.8 40.3 13.5
Car 75.3 55.3 20.0
Combined 65.9 50.1 15.9
Table 6.2: Namapara: before <strong>and</strong> after speed data
Namapara Baseline speed (km/h) Endline (km/h) Dif ference (km/h)
Bus 67.3 55.4 12.0
Truck 50.6 40.4 10.2
Car 70.4 55.3 15.1
Combined 62.8 50.4 12.4
Table 6.3: Kunderpara: before <strong>and</strong> after speed data
Kunderpara Baseline <strong>Speed</strong> (km/h) End line(km/h) Dif ference(km/h)
Bus 72.3 58.5 13.7
Truck 53.2 39.3 13.9
Car 75.7 54.6 21.1
Combined 67.1 50.8 16.2
It is accepted practice in the scientific community to select control areas in order to correct
for any influencing factors that have nothing to do with the road safety program but can
affect the outcome of the study.
Gabtoli Bus st<strong>and</strong>, the control location of Nilkuthi <strong>and</strong> Gashirdia, the control location of
Kunderpara showed nearly same traffic behaviour as before which proved the success of
the intervention in reducing the speed of heavy vehicles on the pilot locations.
