Ongoing inspection and maintenance of bridges poses a challenging task for infrastructure owners who must manage large bridge stocks with limited budgets. Drive-by monitoring approaches, using sensors in vehicle, provide promising solution to this challenge. This paper investigates the use response at point-of-contact between tyre as means frequency. An expression is derived allow contact-point...

Animal–vehicle collision is a common danger on highways, especially during nighttime driving. Its likelihood affected not only by the low visibility hours, but also unpredictability of animals’ actions when vehicle nearby. Extensive research has shown that lack hours can be addressed using thermal imaging. However, to our knowledge, little been undertaken predicting animal action through an ani...

The use of radar in automotive applications such as adaptive cruise control is limited to detecting target vehicles directly in front of the host vehicle. Vehicles around a curve on a highway and cross traffic vehicles at an intersection cannot be detected by current radar systems. This is primarily due to the limited beam width angle of the radar. The first part of this report examines and eva...

Maryland (MD) recently became one of fourteen states in the United States to enact a traffic law requiring motor vehicles to pass bicyclists at a distance of greater than three feet. To our knowledge, motorist compliance with the law has never been assessed. This study measured the distance between overtaking motor vehicles and cyclists [e.g. vehicle passing distance (VPD)], to develop baseline...

although there are remarkable differences in drivers’ behavior as well as vehicles characteristics, road capacity estimationmethods in developing countries are same as developed ones. so, the discrepancy between the theoretical andpractical values of capacity is inevitable. although, capacity estimation methods can be classified based on numerousparameters, in developing countries, the availabi...

An air quality study was performed outside a cluster of schools in the East Harlem neighborhood of New York City. PM(2.5) and black carbon concentrations were monitored using real-time equipment with a one-minute averaging interval. Monitoring was performed at 1:45-3:30 PM during school days over the period October 31-November 17, 2006. The designated time period was chosen to capture vehicle e...

Overtaking is a maneuver that consists of passing another vehicle traveling on the same trajectory, but at slower speed. considered one most dangerous, delicate and complex maneuvers performed by vehicle, as it requires quick assessment distance speed to be overtaken, also estimation available space for maneuver. In particular, drivers have difficulty overtaking in presence vehicles coming othe...

Abstract On roads that cross the slope is often required evaluation of need for retaining construction (road). In design construction, one main factors must be known amount horizontal ground pressure occurs. The consists it self and due to other loads such as vehicles passing on it. constant stationary different from a running vehicle. This study was conducted determine how additional influence...

Vehicle vibrations significantly affect the health and comfort of driver passengers. The aim this study is to analyze effects vertical vehicle caused by speed bumpers on driver's lower back neck in terms forces. To achieve goal, a human biodynamic model with 11 degrees freedom was included half 5 freedom. This composite subjected half-sinusoidal shaped bumps different sizes (heights widths) spe...
