Unmanned Aerial Vehicles (UAVs) promise a low cost means to achieve a "bird's eye view" and a rapid response for a wide array of transportation operations and planning applications, including incident response, coordination among a network of traffic signals, traveler information, emergency vehicle guidance, and measurement of typical roadway usage.(More)
This study quantifies the relationship between perceived and actual waiting times experienced by passengers awaiting the arrival of a bus at a bus stop. Understanding such a relationship would be useful in quantifying the value of providing realtime information to passengers on the time until the next bus is expected to arrive at a bus stop. Data on(More)
State departments of transportation (DOTs), as well as national agencies in many countries, invest heavily in personnel and equipment to collect the data supporting the estimation of Average Annual Daily Traffic (AADT) and Vehicle Distance Traveled (VDT). Satelliteand air-based imagery can provide additional data for estimation and offers certain advantages(More)
Previous attempts to develop an animal model of bullous pemphigoid (BP) have failed to result in inflammatory disease in the skin. P1-2 is an 18-amino acid peptide encoded for by the 230-kD BP antigen cDNA that has been shown to contain an epitope recognized by circulating antibodies from patients with BP. The purpose of this study was to determine if(More)
The availability of traffic flow data on urban roads, as presently collected, is limited due to the sparse number of sensors over the spatially extensive network. We describe a prototype implementation of a sensor and data analysis system that could be deployed on transit or municipal vehicles to collect traffic flow data. It consists of a data collection(More)
