“…The amount of shock, which might harm the health of occupants, depends on the operating speed, speed hump geometry, vehicle type, the position of occupants, and evaluation method (Khorshid, Alkalby, & Kamal, 2007). To figure out the impact of a trapezoidal speed hump on the driver and the occupant vibrations were analysed depending on the slope of a trapezoidal speed hump.…”

“…The root-mean-square acceleration value was calculated for 3 seconds time interval and 32 periods since it is the average number of speed humps passed daily in normal conditions by professional drivers (Khorshid, Alkalby, & Kamal, 2007). However, the number of passed daily speed humps may be higher, as in Teschke, Nicol, Davies, and Ju (1999) study where this number was 264.…”

“…The geometry of a hump is a significant factor in altering the level of these shocks and specifying the speed limit (Khorshid, Alkalby, & Kamal, 2007). Watts (1973) stated that the ideal speed hump should be crossed without damage to vehicle or load, without loss of control or driver comfort.…”

“…The experimental work by Granlund, Lindstroms, and Vägen (2003) demonstrated a high level of shocks introduced to the occupants while crossing speed humps. There are several reported Scandinavian injury cases when passing the traffic calming speed humps by bus (Khorshid, Alkalby, & Kamal, 2007).…”

Abstract.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. The key measures of speed control are educational activities and engineering traffic calming measures. This paper presents an investigation of trapezoidal speed humps -one of the traffic calming measures -and their impact on the driver and the occupants of the vehicle. The level of discomfort to the driver and the occupants, caused by vibrations when the vehicle passes the speed hump, was determined during experimental research. The discomfort level, calculated by three methods, indicated the leading cause of discomfort generated by the analysed trapezoidal speed humps.

Abstrak. Polisi tidur biasanya digunakan untuk mengontrol kecepatan kendaraan dan juga berfungsi sebagai keamanan pejalan kaki. Dalam makalah ini kami mengusulkan desain dan pemodelan sebuah polisi tidur yang dapat menghasilkan energi listrik hingga beberapa ratus watt. Mekanisme gerakan kendaraan yang melewati polisi tidur memungkinkan gerakan naik dan turun yang akan diubah menjadi energi listrik oleh generator. Dalam makalah ini akan dibahas mekanisme respon kecepatan turun speed bump terhadap variasi kecepatan kendaraan dengan cara pemodelan fisik dan simulasinya. Kecepatan turun maksimum yang dihasilkan dari desain speed bump ini kurang lebih 2,3 m/s ketika sebuah kendaraan melewati prototipe ini dengan kecepatan rata-rata 5 km/jam. Kata kunci : polisi tidur/speed bump, energi listrik, pemodelan fisik, simulasiAbstract. Speed bump is typically used to control the speed of the vehicle and also serves as a pedestrian safety. In this paper we propose the design and modeling of a speed bump that can generate electricity up to several hundred watts. The mechanism of movement of vehicles that pass through bumps allow movement up and down is converted into electrical energy by a dc generator. In this paper will discuss the mechanism of speed down response the speed bump to the variation of vehicle speed by means of physical modeling and simulation. As result, the maximum speed down of this speed bump design is approximately 2.3 m/s when a vehicle passes this prototype with an average speed of 5 km/h.
