A Theoretical Overview of Road Hump Effects on Traffic Speed in Residential Environments

Abstract

This paper is part of an ongoing study to analyse the effectiveness of road humps as a traffic calming measure in improving the residential living environment. A review was conducted on various literatures concerning the effects of road humps on vehicle speeds, particularly in residential areas. The major findings from the literatures are that the vehicles’ operating speeds are affected by the hump design and spacing in between humps. An incorrect hump profile will also potentially result in passenger discomfort and vehicle damage. Public perceptions also agreed that road humps are effective in reducing vehicle speeds. More studies should link field study results with residents’ perceptions particularly in Malaysia, while considering the effect of road geometrics and other devices possibly impacting vehicle speeds along selected roads. Further research also needs to be done to test the effectiveness of current schemes in Malaysian residential areas, as many are on an ad-hoc basis.

“…On the other hand, the analogous measure consisting of the sequence of speed tables in Zone 2 (h = 4 cm) results in a significant tendency of road users to drive at speeds above the 30 km/h limit, which is insufficient overall to fulfil the task of limiting speed within the prescribed limit. These results are in agreement with numerous previous studies that have shown that the effectiveness of traffic calming measures has a strong positive correlation with the height dimension of the vertical speed control device [43][44][45]. Zone 3, on the other hand, provides an overall "acceptable" performance and can be considered sufficiently suitable for the role of traffic calming aimed at limiting the driving speed below the legal limit of 30 km/h.…”

“…Hence, the type of vehicles on residential roads can range from motorcycles to middle-sized lorries. The speed limit for residential roads is typically below 35 km/h but the actual travel speed of vehicles may range from 18.6 km/h to 44.7 km/h [6][7]. As for the parking lots inside of buildings, the vehicles are typically motorcycles and cars while larger vehicles such as lorries are designated for the loading bay and their assigned sections.…”

Evaluating the Effectiveness of Road Humps in Reducing Vehicle Speed: Case Study of a University Campus

“…Various types of road humps are either prefabricated or built on-site, and different designs are often used. Geometric and layout designs must be taken into consideration in order to effectively control the vehicle speed [4]- [8]. The geometric design of speed humps deals with the shape and size of individual road humps.…”
