Using Lighting to Alter Driver Behavior

Safety and traffic flow issues are related to drivers selecting inappropriate speeds when driving. For example, at some curved interchange exit ramps, drivers may go too fast, increasing the risk of rollover crashes, especially for heavy trucks. At other locations, perceived 'bottlenecks' in roadway geometry may cause some drivers to slow down more than is appropriate, resulting in variations among vehicle speeds, and increasing the likelihood of traffic congestion, delays and rear-end crashes.

Phase II of Dynamic Toll Lane Microsimulation Calibration and Simulation: Improving Mobility by developing new pricing and control strategies for Dynamic Toll Lanes

This project constitutes a research effort to verify and calibrate a Dynamic Toll Lane (DTL) microsimulation model (Phase I) that will be used to test innovative pricing and control strategies aimed at reducing congestion (Phase II), specifically in a DTL and the main tollway lanes in the Metropolitan Area of San Juan, PR. The DTL was built recently and has already experienced congestion at the entrances and exits. The primary objective of this facility is to reduce, in some way, the time it takes to traverse the congested section of the freeway during peak hours.

Protection Technologies for Bridges Against Overheight Impacts

Impact by overheight trucks on highways bridges has been identified to be a serious problem by numerous studies in the past, including a detailed study by the PI in 2011.  Most of the countermeasures for preventing impact of trucks on bridges utilize monitoring for truck heights to warn truck drivers.  However, despite these systems being installed, bridges are still being impacted and some bridges suffer serious damage, particularly to fascia girders and decks.

Feasibility of employee shuttles for equitable mobility and improved housing options for low- and middle-income employees: A Case for Stony Brook University Campus

The objective of this project is to assess the feasibility of an employee shuttle for Stony Brook University (SBU) campus employees to reduce car dependency and to expand employee access to more affordable housing choices. The ultimate aim of the project is to develop a demand responsive employee shuttle pilot through an online mobility platform for work-home commute, complemented by on-demand service for noncommute trips (e.g., grocery) and carpool matching.

Transportation Risk and Resilience Metrics

This research, addressing the areas of Inclusive Advanced Technology Application and Climate Resilient Infrastructure, will evaluate a set of proof-of-concept transportation resilience measures to determine their utility and scalability as state and local performance measures. The research will review the latest scientific literature on risk and resilience measures to catalog methodologies scoring road network assets based on road segment attributes, hazard intersections, network centrality, and accessibility.

Evaluating a Microhub Pilot Program

Rapid urbanization in cities like New York City (NYC) has spurred an overwhelming surge in consumer demand, with a consequential 80% of deliveries now aimed at residential customers. Predominantly facilitated by trucks, which account for 90% of deliveries, this has detrimentally impacted air quality, traffic congestion, and overall life quality. In response, NYC has initiated the concept of micro-distribution centers or microhubs—spaces designed to transition deliveries from larger trucks to sustainable modes such as electric vehicles or cargo cycles.
