The southwest Kansas region is one of the centers in the United States for the production of processed beef and related industries. Trucks utilized to support these industries cause noteworthy damages to the regional highway pavements. The objective of this research project was to determine the pavement damage cost of a typical highway section in southwest Kansas attributed to the truck traffic...

Widening a highway toll plaza, border crossing or other checkpoint by adding travel lanes and vehicleprocessing stations in parallel fashion can be expensive, and sometimes even infeasible. Rather than expanding laterally, checkpoint capacities can be increased by branching or staggering the vehicleprocessing stations, or by placing them in tandem. Analytical models are formulated to estimate t...

I recent years there has been a growing concern over the congested conditions of our urban highway facilities. The continuing escalation of adverse driving conditions in major urban areas has generated a feeling of discontent among automobile owners and transportation planners alike. One major factor that has contributed to this feeling of dissatisfaction is the rapid pace with which many of th...

The current procedure in the Highway Capacity Manual 2000 for analyzing actuated signalized intersections treats pedestrian crossing and timing in a fixed manner, which can lead to erroneous results in capacity and delay calculations. This paper introduces a new model that remedies such a shortcoming in the current procedure. The model takes into account the stochastic nature of pedestrian cros...

Transportation networks and governments are both hierarchically organized. In some states state government finances most of the highways, while in other states similar roads are financed locally. Larger governments attain scale economies. However they also tend to be more bureaucratic and have higher operating costs, all else equal, due to problems such as span of control. This study relates hi...

Micro-simulation models are rapidly gaining acceptance as promising tools to analyse and evaluate ITS and other traffic control and management measures. Capacity is a primary concept in most of traffic engineering studies, however micro-simulation models generally ignore this concept. There are significant numbers of studies on capacity analysis based on analytical approaches including Highway ...

This paper presents a model for manual and automated traac ow. The model is based on the abstraction of vehicle activities by the space and time taken up by the vehicle engaged in the activity. The manual driver model includes the activities of vehicle following and lane change and allows for diierent levels of aggressiveness of drivers. The parameters of the activities are calibrated with real...

With the rapid development of the national economy of China, an increasing need for transportation facilities is becoming a serious challenge that the existing traffic system has to meet. Thus, the highway transportation capacity development level assessment has important significance in theory and in practice. In order to overcome the current defects of stronger subjectivity and experience in ...
