Traffic calming devices become more favorable for many cities to manage traffic in urban as well as neighborhood areas. Many developing cities already initiated the implementation, while the process has a wide variation in both quality and quantity. The objective of this study is to evaluate the justification of speed humps in urban roads and also to recommend a guideline for installation of speed humps as a traffic calming device in Dhaka city, Bangladesh. It was found that there are vast variations in the implementation, while general public also express an immense disparity of perception about devices quality and suitability and their agreement. Lesson learned from Dhaka City shows that selecting an appropriate placement and dimension of the traffic humps is an urgent requirement to be solved by government by providing standards, guidelines, and policy when there is an initiative to implement or improve traffic calming application.
