Relating the 2010 Signalized Intersection Methodology to Alternate Approaches in the Context of NYC Applications and Priorities

The Highway Capacity Manual (HCM) has had a delay-based level of service methodology for signalized intersections since 1985. The upcoming edition of the HCM (2010) will revise that method. This is happening concurrent with such jurisdictions as NYC reviewing the use of the HCM method in their environmental impact regulations (e.g. CEQR process), and concurrent with a dialog in the profession on when it is appropriate to use simulation models in lieu of HCM methods.

Incorporating Mobile Technology into the GPS/Web-GIS Method for Travel Survey and Research

Traditional paper and phone travel surveys are expensive, time consuming, and have problems of missing trips, illogical trip sequences, and imprecise travel time. GPS-based travel surveys can avoid many of these problems and are becoming increasingly popular in major cities worldwide. However, there is GPS signal loss or degradation in high-density cities such as NYC where urban canyon effects are significant, underground subway and commuter rail travels are extensive, GPS cold/warm start problems are obvious, and mixed land use is common.

Improving Seasonal Adjustment Factors for Better AADT Estimation using Network Interpolation Techniques

Annual average daily traffic (AADT) values play an important role in transportation design, operation, and planning. Each year, transportation agencies spend a significant amount of resources collecting this information. However, AADT values are mostly rough estimates based on the closest short-period traffic counts, factored up using adjustment factors derived from permanent continuous count stations.

Computational Modeling of Driver Speed Control with its Applications in Developing Intelligent Transportation Systems to Prevent Speeding-Related Accidents

Speeding – exceeding posted speed limits, driving too fast for conditions or racing – is the leading contributing factor in fatal motor vehicle accidents in NY State. More than 34 percent of all fatal accidents were due to unsafe speed in 2009 (Summary of Motor Vehicle Accidents, NY State Department of Motor Vehicles, 2009).

Dr. Xuegang (Jeff) Ban

Dr. Ban’s research interests are in transportation network system modeling and simulation, urban traffic system modeling and operations, and Intelligent Transportation Systems (ITS). He develops modeling tools to study dynamic transportation networks with emerging technologies and systems such as connected/automated vehicles and shared mobility. He also works on urban traffic system state estimation/prediction using mobile sensing data.

Dr. Jess W. Everett

Dr. Everett is a Professor of Environmental Engineering in the Civil & Environmental Engineering Department at Rowan University. He teaches Engineering Clinic, Civil Engineering Systems, Engineering Graphics, Sustainable Civil & Environmental Engineering, and upper level Environmental Electives. His research interests are in Sustainable Design, Solid and Hazardous Waste Management, Site Remediation, and Education Innovation. Dr. Everett has been at Rowan since Fall 1998. Before that he was an Associate Professor at the University of Oklahoma.

Dr. Ralph Alan Dusseau

Ralph Alan Dusseau is the DRBA Professor and Chair of Civil and Environmental Engineering at Rowan University. He received his bachelors, masters, and doctoral degrees from Michigan State University. Dr. Dusseau’s masters thesis and doctoral dissertation both involved finite- element analysis of steel arch bridges. He spent 10 years as an Assistant and Associate Professor of Civil and Environmental Engineering at Wayne State University.

Dr. Hao Wang

Dr. Wang’s general research is in the field of sustainable and resilient built environment. His recent research focuses on: 1) multi-scale modeling and characterization of pavement material and development of multi-functional infrastructure material; 2) vehicle-pavement-environment interaction for long-lasting pavement in highway and airfield; 3) life-cycle analysis and assessment and pavement management system. His research has been sponsored by a number of Federal, State, and Local transportation agencies.

Dr. Trefor P. Williams

Dr. Trefor P. Williams is a Professor of Civil Engineering and Senior Researcher at the Rutgers Center for Advanced Infrastructure and Transportation. He has 30 years of academic and consulting experience in the areas of construction management, and transportation engineering. Dr. Williams has five years of professional experience with Wilbur Smith and Associates as a traffic engineer responsible for the installation and initial operation of several computerized ITS systems. Dr. Williams has been a researcher at Rutgers for the last 25 years. Dr.
