Multilane roads in high level-of-detail (LoD) datasets normally represent the constructed high-level roads of urban road network, which have large capacity of transportation and form the pattern of urban movement flows. They are crucial elements for many modern applications such as traffic planning, location-based services (LBS) and emergency evacuation. Nowadays, more and more Volunteered Geog...

Title of Dissertation: A ROBUST MODEL FOR ESTIMATING FREEWAY DYNAMIC ORIGIN-DESTINATION MATRICES Pei-Wei Lin, Doctor of Philosophy, 2006 Dissertation directed by: Professor Gang-Len Chang Department of Civil and Environmental Engineering The purpose of this study is to develop an effective model and algorithm for estimating dynamic Origin-Destination demands for freeways. The primary challenge ...

This paper aims to evaluate and compare the effects of different methods of ramp metering on the operational conditions of traffic flow at three levels: the network level (including the freeway and its connected ramps), the entrance ramp, and the upstream segment of the entrance. To achieve this aim, one of the most important urban freeways in the metropolis of Isfahan was selected. The traffic...

Some users of virtual environments experience adverse effects known as simulator sickness. Common symptoms are generally grouped into nausea, oculomotor discomfort, and disorientation. This research examined whether the severity and type of simulator sickness differs due to the type of driving environment or the gender of the driver. Three environments with variations in driver workload were de...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. 16. Abstract Traffic congestion is an increasing problem in the nation’s urban areas, leading to personal inconvenience, increased pollution, hampered economic productivity, and reduced quality of life. While traffic congestion tends to continuously increa...

By the end of 2014, the total mileages of freeway in China have reached 112,000 kilometers, ranking the first in the world. Most of freeways are four-lane or six-lane, for which inside shoulder is not required by current Chinese guidelines. The inside shoulder is designed to reduce the possibility of fatal traffic accidents on freeways. In China, “Technical Standard of Highway Engineering” regu...

Identifying factors that affect crash injury severity and understanding how these factors affect injury severity is critical in planning and implementing highway safety improvement programs. Factors such as driver-related, traffic-related, environment-related and geometric design-related were considered when developing statistical models to predict the effects of these factors on the severity o...

This paper describes Rutgers Incident Management System (RIMS) software that is developed to evaluate the benefits of various incident management strategies and technologies. This tool can generate incidents and test various response strategies and technologies. South Jersey highway network is used as a test network due to the available historical incident data. The evaluated incident managemen...

Crash Modification Factors (CMFs) are used to represent the effects on crashes of changes to highway design elements and are usually obtained from observational studies based on reported crashes. The design element of interest for this paper is horizontal curvature on rural 2-lane highways. The data for this study came from the Washington State database in the Highway Safety Information System ...
