Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...

the exponential growth of the flow of goods and passengers, fragility of certain products and the need for the optimization of transport costs impose on carriers to use more and more multimodal transport. in addition, the need for intermodal transport policy has been strongly driven by environmental concerns and to benefit from the combination of different modes of transport to cope with the in...

Developing multi-motor solutions for electric vehicles becomes an opportunity in order to reduce the size of each motor, approach mechanical energy production wheels and provide performance optimization. For a given situation, e-drive calculation has cover vehicle operational area defined by requested driving cycle. By applying harmonized test procedure with representative testing cycle data, r...

This paper presents an efficient design for a lateral control synthesis of off-road vehicle. The considered vehicles have two steering axles and are intended to move on slippery soil with important longitudinal slopes. proposed relies extended bicycle model that accounts the is designed based feed forward/feedback architecture. forward takes advantage knowledge path characteristics (curvature s...

One of the problems facing the introduction of novel crops is the concerns about their spread into the natural environment. A long-term study of oilseed rape (canola) growing on the verges of one of Britain’s busiest motorways provides some encouragement that at least some crops find the going tough outside the field environment in which they are sown. Michael Crawley at Imperial College London...

The use of amphetamines in Brazil is common among truck drivers, which may be an important factor in the occurrence of traffic accidents. This article seeks to estimate the prevalence of amphetamine use among truck drivers. Drivers (N = 134) were stopped on two different highways in Sao Paulo state and they were asked to answer a questionnaire and provide a urine sample for toxicological analys...

A 55 year old driver left after Fajr prayer to the vegetable market to buy a few things for his daughter’s wedding lunch. While trying to avoid a big pothole in the middle of the road, he was hit by a truck without headlights coming from the opposite direction. The truck driver continued driving as if nothing had happened. None of the road users cared to help the victim but he was able to conta...

In November 2003, the City of Hamilton, Ontario, Canada equipped five solid waste collection trucks with Trimble Telvisant CrossCheck® GPRS 1900 Mobile data recorders. Three of the trucks are garbage packers, the fourth truck is a side-loading recycling truck, and the fifth vehicle is a 60/40-split co-collection truck equipped with a cart lifter. These trucks operated in a variety of situations...

Gate and yard congestion is a typical type of container port congestion, which prevents trucks from traveling freely has become the bottleneck that constrains productivity. In addition, urban traffic increases uncertainty truck arrival time additional costs. More more terminals are adopting appointment system (TAS), tries to manage arrivals evenly all day long. Extending existing research, this...
