The Best Location for Speed Bump Installation Using Taguchi and Classical Design of Experiments

ABSTRACT

Speed bumps as a traffic-calming technique can be a key issue in ensuring safe passage through secondary roads. Limited works in finding the best location of speed bumps prior to stop points has prompted this investigation. The objectives of this work are to explore the influence of factors in determining the bump location for obtaining the minimum speed at a stop point and to obtain a robust design by investigating the effect of environmental noise on the factors. The mathematical models effectively explain the performance indicators within the range of the factors, and the vehicle speed is the most significant factor.

KEYWORDS:

• speed bump location
• classical design of experiments (DOE)
• Taguchi method
• distance–time
• local optimum point
