Decision-makers have long speculated that building separate roads for trucks and passenger cars, or at least separating them on their own lanes would accomplish two major objectives: 1) they would make the roadways safer for passenger cars, and 2) roadways designed specifically for a select class of vehicles rather than for all vehicles might represent overall savings in construction costs. Thi...

15. Supplementary Notes Supported by general revenues from the State of Texas 16. Abstract In recent years, there has been a renewed interest in applying statistical ranking criteria to identify sites on a road network, which potentially present high traffic crash risks or are overrepresented in certain type of crashes, for further engineering evaluation and safety improvement. This requires th...

Non-motorized vehicles (i.e. rickshaws) and small size motorized vehicles (i.e. auto-rickshaws) are popular para-transit modes that provided door-to-door service in congested parts of Dhaka metropolitan area. Improper design of signal timing at signalized intersections is one of the reasons of traffic congestion in Dhaka metropolitan area. For capacity analysis, to convert the mixed traffic flo...

This paper presents an optimisation method to traffic engineer networks carrying different classes of traffic. The novel Mixed Integer Programming model is based on the classical multi-commodity flow problem. Although some initial input data (such as topology and traffic matrix) is required, the method can be directly applied and no protocol or router modifications are necessary. The method rec...

There is significant interest in the network management community about the need to improve existing techniques for clustering multi-variate network traffic flow records so that we can quickly infer underlying traffic patterns. In this paper we investigate the use of clustering techniques to identify interesting traffic patterns in an efficient manner. We develop a framework to deal with mixed ...

The policy of driving organization such as Highways Agency is towards the use of performance related specifications. This policy and adoption of European wide aggregate standards on the one hand, and sustainable construction pressures on the other, all strongly emphasize on further need for more developments to specifications and performance assessment methodologies inst...

In this project we investigate the effect of heavy-duty trucks, equipped with different Adaptive Cruise Control (ACC) systems, operating in mixed traffic with manually driven passenger vehicles, on the environment and traffic flow characteristics. The sluggish dynamics of trucks whether manual or ACC that is due to their limited acceleration capabilities filters speed disturbances caused by lea...

Congestion control is a distributed algorithm to share network bandwidth among competing users on the Internet. In the common case, quick response time for mice traffic (HTTP traffic) is desired when mixed with elephant traffic (FTP traffic). The current approach using loss-based with Additive Increase, Multiplicative Decrease (AIMD) is too greedy and eventually, most of the network bandwidth w...

BACKGROUND Fine particulate matters with aerodynamic diameters smaller than 2.5 micrometers (PM2.5) have been a critical environmental problem in China due to the rapid road vehicle growth in recent years. To date, most methods available to estimate traffic contributions to ambient PM2.5 concentration are often hampered by the need for collecting data on traffic volume, vehicle type and emissio...
