摘要: |
The primary objectives of this research study are (1) to deploy some promising low-cost portable and integrated multi sensor systems for data-driven performance evaluation of urban transportation networks and (2) to develop a system capable of real-time remote monitoring of external changes, such as air quality, noise, humidity, temperature, and crowd and vehicular densities in an urban setting. This report describes the design, fabrication, and characterization of such a portable and integrated multi-sensor system for the performance evaluation of urban transportation networks and their environmental impacts. The system uses multiple low-cost, yet effective, sensors to capture particulate matter level, humidity, and temperature of ambient air as well as pedestrian and vehicular traffic. The major outcome of this research project is the development of a smart sensing system capable of acquiring and then sending detailed critical environmental and traffic information wireless from the fixed installation location to a remote server with the ultimate goal of making on- and off-line decisions to improve urban operations. |
