The Open Mode Integrated Transportation System (OMITS) has been designed as an effective, convenient, dynamic and safe transit system making carpooling or vanpooling service available for metropolitan areas and inter-cities. OMITS forms a sustainable information infrastructure for communication within and between the mobile/ Internet network, the roadway network, and the users’ social network. It manipulates the speed gap between different types of the networks.

This research project explores sustainable transportation programming and policy on university campuses by evaluating a transit pass program in which select students, faculty, and staff at the University at Buffalo were issued pre-paid unlimited transit passes for Metro Rail, the light rail system operated by the Niagara Frontier Transportation Authority.

The introduction of larger aircrafts on flexible airfield pavements has led to a need for asphalt mixtures capable of sustaining such heavy loads. This laboratory and analytical study investigated the mechanical responses of a number of modified asphalt mixtures to identify their potential for use in airfield aprons and taxiways that are subjected to heavy, static or slow-moving aircraft loads.

In this project, we derived a latent class model with a class assignment mechanism based on the latent bicycle status of the respondent. Two segments were identified: more-skilled and experienced cyclists, versus less-skilled- and non-cyclists. The two segments have different sensitivities to the factors that may encourage or discourage riding a bike. For instance, slope inclination is considered almost 3 times as bad by less-skilled cyclists.

Alkali-activated concrete (AAC) is an emerging technology in the construction materials sector. Cement-free AAC is a promising environmentally-friendly alternative to ordinary portland cement (OPC) concrete. A comprehensive study was performed by researchers at Clarkson University to develop energy efficient and environmentally friendly cement-free concrete mixtures for pavement and bridge deck applications. Alkali-activated concrete (AAC) mixtures were developed using slag and fly ash as the sole binder and sodium silicate as the alkaline activating solution.

This project develops a method for predicting coastal flooding considering climate change and sea level rise, and its impact on population and transportation network. In particular, a modeling framework has been proposed to predict flooding and estimate affected population and traffic systems needed for evacuation plans, and the following tasks have been conducted:

In this project we report a comprehensive assessment of the power that is available for harvesting in the vehicle suspension system and the tradeoff among energy harvesting, ride comfort, and road handing with analysis, simulations, and experiments. The excitation from road irregularity is modeled as a stationary random process with road roughness suggested in the ISO standard.

Abstract: An effi cient electromagnetic energy harvester featured with mechanical motion rectifi er (MMR) is designed to recover energy from the vibration-like railroad track defl ections induced by passing trains. Trackside electrical infrastructures for safety and monitoring typically require a power supply of 10-100 Watts, such as warning signals, switches, and health monitoring systems, while typical existing vibration energy harvester technologies can only harvest sub-watts or milliwatts power.

Road pricing has gained more research attention due to its effectiveness in managing traffic congestion and financing transportation infrastructure during recent years. Most research efforts focus on the functionality of road pricing in managing traffic congestion and raising revenue. In contrast, little is known about the impact of such pricing policies on urban development over time.

Conventional photometric quantities such as illuminance and luminance make the specification and calculation of lighting possible, but are based on human visual responses under a limited range of conditions. Visual perception at nighttime, such as under roadway and vehicle lighting, often occurs under lower light levels and larger visual fields than the conditions used to develop the conventional photometric system.
