In this paper we modify our unsupervised anomaly detection algorithm [1,2] and apply it to highway traffic anomaly analysis. We propose a method to identify anomalies under a probabilistic framework. Instead of determining anomalies based on the size of each cluster, they are determined in a probabilistic framework. Moreover, we present our findings on using different features when analyzing re...

The report attempts to deliver a proof of concept that optimal planning and management strategies can be formulated through applying robust optimization methodology such that limited resources could be allocated more rationally, and reliability of a highway network improved more efficiently. The report focuses on two applications: the network design problem under demand uncertainty, and fleet a...

As the traffic infrastructure for collecting vehicle tolls, capacity of toll plaza determines service level entire highway. The a is highly correlated with its operating costs, especially in peak periods. In this paper, it assumed that competitive transportation system, residential area and workplace are connected by highway which forms bottleneck, parallel to mass transit line; commuters can c...

Speed, flow and volume are the most important elements of the traffic flow. In this study, the speed-density regression models are compared between congested city road and the tolled highway based on traffic flow data on Beijing Third Ring Road (BTRR) and Jing Jin Tang Highway (JJTH) in China, which are collected by road detectors on each road. The speed-density regression curves are analyzed b...

Highway systems play a key role in providing mobility to society, especially during emergency situations, including earthquakes. Bridges highway are susceptible damage from earthquakes, causing traffic capacity loss leading serious impact on surrounding areas. To better prepare for such scenarios, it is important estimate and disruptions For this purpose, traffic-capacity-analysisbased methodol...

The intersection is a significant part of the urban traffic network. One problems signalized intersections results an analysis that do not match field. For border crossings in 1997 Indonesia, Indonesia Highway Capacity Manual, product 1994 data processing, was used. Traffic conditions were, course, different from today. Given changes related to traffic, such as increases number vehicles, land u...

The urban weaving sections are more complex due to the various disturbing elements within section, such as lane-change situations. These turbulences reduced road capacity and increased vehicle exhaust emissions. Highway Capacity Manual (HCM 2010) has a methodology for analysis of free highways; roads is not investigated in HCM. Therefore, main objective this research present systematic factors ...

| The work presented here is part of a bigger eeort to design an automated highway system to improve the capacity and safety of the current highways. Automation of highways and in particular platooning of vehicles raises a number of control issues. In the design proposed in 1] these issues are addressed by a hierarchical structure consisting of both discrete event and continuous controllers. Ou...

Across the nation, traffic growth and congestion continue to outpace growth in highway capacity. A large amount of this congestion occurs at intersections, rather than along the links between intersections, it is of utmost importance that traffic engineers use every available technique for improving intersection performance and safety. This paper examines the benefits of roundabouts as an alter...

The pavement deflection measured by falling weight deflectometer (FWD) detection equipment can be used to determine the bearing capacity of a structure through modulus backcalculation provide suggestions for maintenance. However, because asphalt mixtures are temperature-sensitive materials, they greatly affected temperature, and changes in temperature cause their mechanical properties vary affe...
