Sky glow light pollution is caused largely by reflected light off of roadway and other surfaces. The authors investigated the feasibility of a system consisting of a specialized LED streetlight and a dye-based roadway surface coating that would reduce sky glow, but still provide adequate illumination of objects in the road.
This report analyzes the use of social media tools by the New York region’s major transportation providers. It is focused on the effectiveness of their Twitter feeds, which were chosen for their immediacy and simplicity in messaging, and provided a common denominator for comparison between the various transportation providers considered, both public and private. Based on this analysis, recommendations are outlined for improving social media outreach.
GPS-based travel surveys can avoid many problems of traditional paper and phone surveys and are becoming increasingly popular in major cities worldwide. We developed a Web GIS prototype in this project to collect GPS data from survey participants, detect travel modes and trip purposes, and allow survey participants to modify the results in a Web GIS.
The goal of this project was to develop a new, effective and low-cost media for sustainable management of polluted road stormwater in highly urbanized areas. The overarching objective of this study was to provide the scientific basis for the development and utilization of a novel media consisting of wood mulch coated with a recycled solid waste -- water treatment residuals (WTR) -- for the removal of multiple pollutants (namely, Cu, Pb, Zn and P) from urban road runoff.
The primary objectives of this research study are to deploy low-cost portable and integrated multi sensor systems for data-driven performance evaluation of urban transportation networks and to develop a system capable of real-time remote monitoring of external changes, such as air quality, noise, humidity, temperature, and crowd and vehicular densities in an urban setting.
In recent years, there has been a significant shift in how people use the transportation system. New technologies have resulted in new trends surrounding transportation. In this study, three emerging trends were considered: delivery lockers, crowd delivery, and autonomous vehicles.
Probe vehicle speed data has become an important data source for evaluating the congestion performance of highways and arterial roads. Predefined spatially located segments known as Traffic Message Channels (TMCs) are linked to commercially available, temporal anonymous probe vehicle speed data. This data has been used to develop performance measures for roadways to better plan and manage infrastructure assets.
Demand for vehicle and public transportation systems continues to increase in and around major urban centers. This increase is especially pronounced during the morning and evening commutes and is further complicated by the complex spatial interactions that influence the variation in system demand.
Traffic congestion is an important aspect of quality of life, mobility and accessibility in urban areas. The economic cost of congestion is in the order of billions of dollars especially for dense urban cities. Besides the congestion which relates to the magnitude of travel time, travel time variability is also studied extensively by researchers as an additional measure for transportation network efficiency. In order to enhance the efficiency of urban traffic flow in New York City (NYC), numerous policies have been discussed, including different transportation pricing schemes.
