“…The study conducted by Bekheet (2014), Abdel-Wahed, and Hashim (2017) evaluated the impact of speed humps on the performance of pavement condition, whereas Patel and Vasudevan (2016) focused on the effects of speed humps on bicycle riders. Barbosa et al (2000), Antic et al (2013), Abdulmawjoud et al (2020), andYeo et al (2020) investigated the influence of traffic calming measures on the vehicle speed profile. The study conducted by Antic et al (2013) was an interesting study as it covered the geometrical features related to the speed humps.…”

The heterogeneous traffic conditions in India is making things more complicated in urban areas. Traffic accidents in India are increasing at an alarming rate due to the rapid growth of motor vehicles in the past few years. The number of accidents drop only at sites where speed restriction techniques are implemented for different vehicle categories, especially at locations like approaches to level crossings, negotiation points at sharp curves, approaches towards intersections, accident prone locations, residential streets, streets closures at schools and hospitals etc. In developing countries like India, speed humps and speed bumps are primarily used as speed reducing devices both in urban and rural areas, which is not the case in developed countries where speed bumps are used only on private grounds and speed humps are mainly used on residential roads in urban areas. The effectiveness of speed reducing devices are reviewed in this study to elaborate best practices and recognise gaps in research to set up few scopes for future research in this area. The literature review revealed that most of the speed humps in developing countries have faulty geometrical dimensions when compared to codal provisions leading to problems among road users. Though traditionally speed humps are known to reduce speed and increase safety, they too have disadvantages like, increase in travel time, increase in vehicle operating cost, decrease in capacity of roads and undesirable experience to drivers and passengers. Rumble strips on safety on rural roads on either side of a pedestrian crosswalks is an option to be further explored. Finally, in view of the Indian road conditions, it is observed that Indian guidelines concerning design of speed humps IRC 99-2018 are not compatible with best practice. Therefore, there is an imperial need to frame new guidelines for different type of roads.

“…They concluded that parabolic speed humps are not effective for vehicle speeds above 25 km/h. Abdulmawjoud et al (2020) investigated three types of traffic calming measures located in Mosul city. They have collected the data like vehicle headways, travel times, delays, and driving speed at different locations.…”

“…Previous research generally analyzed traffic-calming designs using three methods: a laboratory research environment (i.e., a simulator) [5,8], controlled environment (i.e., an instrumented vehicle) [9], and real-world environment (i.e., studying drivers' natural behavior in the real world) [7]. Physical and perceptual traffic calming has also been studied extensively near intersection areas.…”

Uncontrolled median openings contribute to more road crashes because drivers do not obey traffic laws such as driving between lanes and following speed limits. This study examined the effectiveness of the different types of signs near an uncontrolled median opening in Mahmoud Abad, Iran. There were Signs 1 and 2 with a single message, while Signs 3 and 4 contained multi-messages. An Internet of Things (IoT) test system was developed to collect and record vehicle speed data before and after each sign installation. Results showed that speeding behavior decreased almost immediately after the road signs were installed and remained almost constant until the beginning of uncontrolled median openings. Moreover, multi-message traffic signs reduce vehicle speeds twice as much as single-message signs. Additionally, only multi-message signs are effective at reducing speed limit violations.

“…Many researchers have also analysed speed reductions, driving paths, decelerations and accelerations imposed by different traffic calming measures, for example, speed humps and speed bumps (Abdulmawjoud [22] and Baltrènas [23]), different configurations and sequences of bulb-outs and chicanes (Akgol [24]) or speed tables, chicanes and road narrowings (Distefano [25,26]). The effects of speed humps and speed tables on the reduction in speed, exhaust emissions and fuel consumption were reported by Obregón-Biosca [27] and Lav [28].…”

The increasing use of road vehicles has caused a number of transport and environmental issues throughout the world. To cope with them, traffic calming schemes are being increasingly implemented in built-up areas. An example of such schemes are Tempo-30 zones. The traffic calming measures applied as part of this scheme must be carefully planned in terms of location and design details in order to obtain the desired reduction in speed, traffic volume and exhaust emissions and, last but foremost, to increase the safety and facilitate the movement of vulnerable road users. The coexistence and combined effect of these measures and their design details must also be taken into account. The purpose of this study was to investigate whether the applied traffic calming measures had a considerable bearing on the reduction in speed to the desired level, as assumed in the traffic calming plan. Three street sections starting and ending with different intersection types were chosen to examine the synergy of the applied traffic calming measures. The numbers and speeds of vehicles were measured in three day-long continuous surveys. As it was expected, the amount of speed reduction depended on the hourly traffic volume on a one-way street and various other traffic engineering aspects. The obtained results may be used to modify the existing speed profile models and can guide traffic engineers in choosing the most effective traffic calming measures.
