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.
