Global Navigation Satellite Systems (GNSS) is becoming one of the main components supporting Intelligent Transport Systems (ITS) and value-added services in road transport and personal mobility. The use of GNSS is expected to grow significantly due to improvements in positioning performance, with positive impacts such as: finding the optimal route; improving traffic and travel efficiency as well as...
The proliferation of GNSS-receiving mobile devices in the consumer market and the growth of the Intelligent Transportation Systems sector have raised a lot of interest in low-cost precise positioning. However, GNSS signal quality is degraded inside the metal body of a vehicle, which is where the antenna of a portable device is to be located. This article investigates the effect of antenna location...
Many Location Based Services (LBS) have emerged in the past few years. However, the provision of underlying positioning technologies to support these services in indoor environments is still challenging. The indoor environment with its propagation complexity presents a burden to achieve affordable, high accuracy and real-time positioning. A recent development, the Improved FOCUSS for Arrival Time...
Precise Point Positioning (PPP) has been one of the major research interests in the Global Navigation Satellite System (GNSS) research field in recent years. PPP is a promising method because it can provide centimeter level positioning accuracy by using only one GNSS receiver, without using local reference networks. It is clear that this can provide cost savings compared to the traditional Real Time...
The objective of this paper is to derive quantitative measures for road user charging (RUC). Instead of using complicated sensors to measure pollutant emissions and driver behavior, this paper uses location, velocity, acceleration and time (LVAT) determined by most widely used GPS receivers together with supporting information to derive indirect quantitative indicators for emissions and driver behavior...
