Weigh-in-motion (WIM) systems might soon replace the conventional techniques used to enforce
weight restrictions for large vehicles on highways. Currently WIM systems use a piezoelectric
polymer sensor that produces a voltage proportional to an applied pressure or load. Using this
phenomenon, these systems are already being tested for collecting traffic data, including weigh-inmotion,
measuring vehicle speeds, classifying vehicles by category and counting axles etc. The

Piezoelectric sensors are being tested for collecting traffic data, including weigh-in-motion, measuring vehicle speeds, classifying vehicles by category and counting axles etc. There are two types of these sensors ? polymer and ceramic. Currently WIM systems use a piezoelectric polymer sensor that produces a voltage proportional to an applied pressure or load. The polymer sensors are usually in the form of a long tape or cable embedded within a long block of elastomeric material. These blocks are installed into grooves, which are cut into roads perpendicular to the traffic flow.

As more and more people have forsaken city-center activities in favor of out-of-town shopping malls and business parks, many downtown areas in the United States have been allowed to fall into neglect. Will Central Business Districts (CBDs) or 'Main Streets' survive these forces? Unless proper measures are taken and necessary investments made now, the future of Main Streets may be in danger. Is it worth investing in Main Streets in New York State?

This report, written by Gary S. Wojcik and David R. Fitzjarrald of the University of Albany, describes the field campaign and subsequent data analysis for the Route 30 bridge over the South Chuctanunda Creek in Montgomery County, NY. The two purposes of this work were 1.) to make more detailed measurements of the bridge environment than we have done in the past to better understand the energy budget of a curing concrete bridge and 2.) to provide atmospheric boundary conditions to a model of curing concrete.

Concrete delamination (spalling) in bridge decks is a serious problem. Damage in reinforced concrete structures is caused by many factors, such as alkali-aggregate reaction, faulty design and construction, reinforcement corrosion, corrosive action of chlorides, geotechnical problems, or in general by mechanical, chemical, physical, biological and environmental loads. The project examined the durability of concrete bridge decks to mechanical and environmental effects, for the purpose of evaluating the effects of blacktop resurfacing of bridge decks.

The objective of this research was to perform evaluation tests related to the transmission of digitized video signals over ISDN between a video traffic reporting camera and a traffic management center. The quality of the received video signals was assessed for effectively monitoring the traffic conditions. An evaluation plan was developed which consisted of a market survey of current video-transmission options, an identification of the hardware specifications for the ISDN connections, and a description of the tests to be performed.

In this study, we investigated how pedestrian traffic contributes to our State?s
economy, and what benefits walk trips or walk trips linked with other travel modes (e.g.,
cars, transit, bicycles, etc.) have for retail sales within communities located on the State
Highway Touring Route System. In New York State there are more than 180 Central
Business Districts (CBDs) or 'Main Streets' located on the State Highway Touring
Route System [1]. However, there is very little data available on the value of these
