Transportation Infrastructure Robustness: Joint Engineering and Economic Analysis

The objectives of this study are to develop a methodology for assessing the robustness of transportation infrastructure facilities and assess the effect of damage to such facilities on travel demand and the facilities users’ welfare. The robustness of transportation facilities is related to two types of damage: a) longitudinal deterioration in facility engineering quality; and b) sudden shock due to unexpected extreme events. This study focuses on the first determinant and its economic implications.

Techniques for Efficient Detection of Rapid Weather Change and Analysis of their Impacts on a Highway Network

Adverse weather conditions have a significant impact on the safety, mobility, and efficiency of highway networks. Annually, 24 percent of all crashes, more than 7,400 roadway fatalities, and over 673,000 crash related injuries were caused by adverse weather conditions between 1995 and 2005 [1]. In addition, weather contributed to 23 percent of all non-reoccurring delay and approximately 544 million vehicle hours of delay each year [2].

Develop Data Storage and Access Platform for MTA Bus Time Data

Travel times can be collected from a large number of potential sources. Conventionally, fixed detectors such as inductive loops embedded in the roadway have been used to measure vehicle flows and estimate speeds. Recent technological advances and the widespread deployment of Global Positioning Systems (GPS) in consumer devices make mobile data sources a promising and potentially cost-effective way to monitor the congestion in a transportation system.

Research on Pedestrians and Cyclists Safety Using ITS Technology in NYC

This research project builds on the work and goals of the New York City Department of Transportation NYCDOT) in its long standing efforts to promote the safety of pedestrians, as described in the Vision Zero Initiative and the NYCDOT’s 2016 Strategic Plan. As part of the Vision Zero Initiative, in 2015, NYCDOT installed over 400 Leading Pedestrian Intervals, and completed 60 safety projects in Vision Zero Priority Locations.

Strategic ITS Deployment Plan for New York City

The Strategic Intelligent Transportation Systems (ITS) Deployment Plan for New York City was last updated in 2005 by Polytechnic University of New York. The New York City region has invested significant resources on ITS deployment in the past decades. It has involved the deployment of an advanced controller (the ASTC), a wireless communication infrastructure (NYCWiN), detectors, and the overall data management system to process information and to communicate the control settings.

Develop a Multi-agency/Multimodal Construction Management Tool to Enhance Coordination Projects City-wide During Planning and Operation Phases to Improve Highway Mobility and Drivers Experience

The main objective of this study is the assessment of the Construction Impact Analysis (CIA) and Work Zone Impact and Strategy Estimator (WISE) tools, and determining the feasibility of their customization with respect to New York City Departme nt of Transportation (NYCDOT) and New York State Department of Transportation (NYSDOT)’s needs and requirements, cost of adoption and modification, and related issues.

Develop a Comprehensive Guide to Traffic Signal Timing, New Detection Technologies and Advanced Signal Timing Concepts Applicable in New York City

The purpose of this guide is to provide some elementary guidance to beginning traffic engineers in the NYCDOT Signal Timing Division on the standards of signal timing in NYC. The guide is intended to provide an understanding of the influence of traffic signal design on traffic operations, and is a primer on traffic signal timing, phasing, and coordination.

Public Transit and Mandatory Evacuations Prior to Extreme Weather Events in New York City

Extreme weather events and their consequences are posing a threat to large urban areas such as New York City. Evacuations are often needed and public transit can play an important role to move people before, during and after such events. Public rail transit is a valuable resource given relatively less attention. The research objective is to identify how public transit’s potential for evacuation varies geographically in NYC, focusing on subways, bus connectivity and evacuation centers. Methods use data analyses for U.S. Census block groups.

Innovative Techniques for Maintenance Repair and Reconstruction (MRR) of Asphalt Roadways

Highway networks in the United States have been suffering from poor operational and structural condition states for the past decades. The consequent congestion problems often result in major delays, safety issues, and large amounts of additional fuel consumption and greenhouse gas emissions. With limited funding available, transportation agencies are placing more emphasis on maintenance, repair, and reconstruction (MRR) practices in order to preserve and restore roadway conditions.
