Mobile sensing enabled by on-board GPS or smart phones has become the primary source of traffic data. For sufficient coverage of the traffic stream, it is important to maintain a reasonable penetration rate of probe vehicles. From the standpoint of estimating higher-order traffic quantities such as acceleration/deceleration, emission rate and fuel consumption rate, it is desirable to examine the effectiveness...
This technical note considers the problem of optimally deploying omnidirectional sensors, with potentially limited sensing radius, in a network-like environment. This model provides a compact and effective description of complex environments as well as a proper representation of road or river networks. We present a two-step procedure based on a discrete-time gradient ascent algorithm to find a local...
