This paper presents a detailed measurement study of short range communications between vehicles and between vehicles and roadside stations in a realistic highway scenario. We show the expected wireless communication characteristics in a driving environment and identify factors that significantly affect communication performance. We also illustrate the(More)
Traffic congestion has been one of major problems in modern cities and thus numerous measures have been taken to mitigate it. An appropriate selection of congestion mitigation strategies comes from the sound understanding of the congestion characteristics. Many researchers, thus, have tried to identify the effective ways for measuring level of congestion or(More)
Speed and acceleration rates are primary parameters in the estimation of instantaneous engine power demand, which can be employed to estimate gram/second emissions in modal activity-based emission rate models. Unlike speed, which is typically measured directly by onboard monitoring systems, acceleration is usually a derived parameter, calculated from(More)
