Current Research:

Project 1

Maintenance, repair and renewal activities have high environmental impacts due to the raw material extraction and construction procedures. In roadway sections where the existing capacity is approximately equal to the demand, these activities also cause work-zone congestion, which result in environmental degradation due to vehicle emissions and social impacts due to delays. Accelerated construction techniques can be used to reduce the project duration and hence, reduce environmental and social impacts of work-zones. Traditionally, maintenance, repair, and renewal activities are designed by considering the agency costs of various alternatives. A more comprehensive approach would require considering the environmental and social impacts of the alternatives in addition to the agency costs. The aim of this study is to identify life-cycle economic, environmental, and social impacts of work-zones, and to examine benefits and costs of accelerated construction techniques in terms of reduction of greenhouse gases, and user costs.

Project 2

One of the primary objectives of Transportation Systems Management and Operation (TSM&O) strategies is to optimize the capacity of existing transportation infrastructure by reducing congestion. Over the past decades, agencies and researchers investigated the use of various strategies such as deployment of advanced traveler information systems, ramp metering, surveillance through closed circuit TV cameras, and synchronized signals to achieve this objective. Life cycle cost analysis (LCCA) of various alternative strategies has received particular attention to identify the strategy with the lowest cost. However, increasing concerns over the impacts of transportation systems on nearby communities as well as the environment are urging decision makers to consider the environmental impacts of various TSM&O strategies in addition to user costs.

Vehicle emissions are affected by various factors such as vehicle’s speed, idling time, and acceleration, which in turn depend on the traffic activities of other vehicles and level of congestion. Changes in highway capacity and pavement condition have an impact on the level of user costs incurred by commuters. There is a lack of decision support systems that would allow decision makers to simultaneously compare environmental, social and economic impacts of TSM&O strategies over their life cycle. The aim of this study is to address this gap in research.

Project 3

Urban water management has been compromised by the addition of impervious surfaces as development spreads from central cities out to suburban areas. Many streams, rivers, and lakes are now sinks for stormwater that previously permeated into soils and recharged groundwater supplies. The problem is twofold. First, the quantity of stormwater runoff has increased due to the increasing size of developed catchment areas that include parking lots, roads, and other impermeable surfaces. Second, the quality of stormwater runoff has degraded as contaminants emitted from vehicles are washed from these surfaces into storm sewers and ultimately reach bodies of water without treatment. In this project, we will estimate the impact of vehicles on the quality of stormwater runoff using Syracuse as a case study. We will obtain information on vehicle miles traveled in sections of the Syracuse metropolitan area and the amounts of various contaminants emitted and deposited on surfaces in the urban area. We will use this information with precipitation intensity and frequency data to model the amount of each contaminant in stormwater runoff. The model results will be compared with concentration measurements for surface runoff collected in areas where input data are known. To the extent possible, a special effort will be made to use known markers of vehicle emissions to determine the contribution of local vehicles to the mix of mobile and stationary source emissions as well as long range transport of contaminants.

Project 4

The objective of this study is to investigate opportunities to reduce the negative impacts of bridge closures due to repair and upgrade activities by: 1. Exploring various alternative construction materials and methods such as use of prefabricated/precast systems, and innovative contracting methods such as A+B bidding, incentive/disincentive contract, and lane rental that can be used to accelerate construction activities of bridges, 2. Identifying important factors -both qualitative and quantitative- which affect the decision-making procedures for selecting the most appropriate upgrade or repair strategy, 3. Providing a decision support framework that will allow evaluation of alternatives. In order to fulfill these objectives, a comprehensive review of the available literature will be performed with a focus on accelerated construction methods and contracts, emergency response procedures, and factors affecting decision-making procedures for selection of appropriate bridge upgrade and repair methods and contracting approaches. In addition, a national survey of state DOTs will be conducted in order to determine the current state of practice throughout the United States. The decision support framework that will be developed in this study will provide a systematic procedure for comparing various upgrade and repair strategies. Thus, decisions regarding selection of appropriate upgrade/repair methods and contracting approaches will be more objective and justifiable.
