Speed Humps

Over the last three decades, transportation has become one of the main energy-consuming sectors around the world and, as a result, large amounts of emissions are produced, contributing to global warming, climate change, and health problems. Therefore, huge investments and efforts have been made by governments and international institutions to find new renewable and clean sources of energy. As a contribution to these efforts, this study determined the practical energy and environmental implications of replacing conventional speed humps with energy-harvesting speed humps in Nablus city, Palestine. The study was implemented using an energy-harvesting speed hump (EHSH) system developed in the laboratories at An-Najah National University and based on comprehensive traffic volume counts at all speed humps’ locations. In addition, a traffic volume prediction model was developed in order to determine the implications over the next 10 years. As a result of the study, the expected annual amount of generated energy was determined. Moreover, the expected reduction in greenhouse gas (GHG) emissions and the reduction in the cost of roadway network lighting were determined based on the current and future traffic conditions.

The paper presents the results of research to develop methodology for a rapid assessment of the effect of measures used to improve road safety. The research includes the improvement of the method of determining traffic conflict situations and the development of accident prediction in conflict situations. A method of conflict situations is one of the most advanced and effective methods for predicting accidents at conflict sites since this method is based on the dependency of the number of accidents on the number of conflict situations. Having determined at the study site the number of conflict situations it is possible to calculate a predictable annual number of accidents at that site. The research implemented gave a possibility to increase the accuracy of accident prediction according to the method of conflict situations making it suitable to be used in practice for assessing the quality of road safety measures at the conflict sites – signalized intersections and pedestrian crossings, in the zone of which the artificial speed humps have been installed, such as a “sleeping policeman”.

Speed Humps

208 motorists were observed at Florida International University, in Miami, Florida as part of a study of the influence of speed humps on motorists' behavior at pedestrian crossings. It was hypothesized that the presence of a speed hump will affect motorists' behavior by compelling them either to yield or stop at a pedestrian crossing to enable a pedestrian to cross safely. A between-subjects experimental design was employed to measure motorists' reactions. Analysis indicated that the relationship is strong between drivers' behavior and the presence or absence of this roadway stimulus. There was also evidence that female drivers may take more precautionary actions than male drivers. This information is useful for roadway designers and traffic psychologists.

Speed Humps

In developed countries, the use of speed humps and bumps have evolved from extensive research and testing which been properly designed and standardized. On the contrary in developing countries, no systematic and scientific studies have been carried out on that environment, especially the study on the effects that the motorcyclists response to the humps and bumps. This study therefore reveals the riders behavior when negotiating their speed to the devices. A case study was conducted in the provincial cities of Thailand where the motorcycle was a major mode of transportation. Six locations with speed humps and bumps were selected. Vehicles passing times were simultaneously recorded at 12 points along each traffic calmed link. From these data, a speed profile for each individual vehicle and for a link could be derived. It is found that speed humps and bumps have critically different impacts on motorcycle rider and passenger car driver. The smaller size speed bumps could effectively control the rider speed but have diverse impacts on the driver. These speed differences could post more safety deficiency to the site. The effect of the device on riders behavior, however, is restricted to a short spatial range (about 20-30 m before and after the device). For the speed humps, the motorcycle speeds are quite varied depending mainly on the road terrain. It is found that the motorcyclists have significant lower acceleration rate on the upgrade terrain when compared to the passenger car. Therefore, it is important to take all these rider characteristics into considerations when design the road humps to control vehicle speed in the developing countries.
