Investigation the Effect of Speed Humps on Merging Time of U-turn Traffic
Ain Shams Engineering Journal, 2019 The median U-turn involving allowing traffic to move toward opposing direction through providing special paths on a highway’ median. Such left turn movements causing delays for both merging and the opposing main stream traffic.

Public Evaluation of Speed Humps Performance and Effectiveness [PDF]
Civil Engineering Journal, 2018 In Egypt, it is believed that speed humps are the cheapest and best solutions to reduce vehicles speed and thus reduce the number of potential accidents. Due to the lack of specifications in Egypt that govern the installation of speed humps, they were spread randomly and with different dimensions without adequate studies.

Analysis and Evaluation of Trapezoidal Speed Humps and Their Impact on the Driver
The Baltic Journal of Road and Bridge Engineering, 2018 Operating speed is one of the leading safety risk factors, which increases accident risk and influences accident severity. Speeding is the leading cause of accidents and the most common road traffic offense.

Distance between speed humps and pedestrian crossings: Does it matter?
Accident Analysis & Prevention, 2011 Speed humps are a common physical measure installed at pedestrian crossings to reduce vehicle speeds therefore improve the safety and mobility of pedestrians at the crossing. The aim of this study was to determine whether variations in distance between speed humps and pedestrian crossings contribute differently to the safety and mobility of pedestrians
