In this paper, we propose a novel multiscale approach to model Virtual Urban Environments thanks to the introduction of a design pattern which links activity places and transportation networks. This environment is also augmented with a synthetic population in order to build the Populated Urban Environment. The meso-simulator TransNetSim has been developed and coupled with the micro-simulator Vi...

Recent interest in using modern roundabouts as an effective and safe method for intersection control in the United States stresses the need for accurate modeling tools. The objective of this paper is to assess the calibration potential of common analytical and micro-simulation roundabout models to operations at modern roundabouts. The models considered were aaSIDRA and RODEL (on the analytical ...

Improving the performance of the QCL through block diagram as well as mathematical models is the main scope of this paper. In order to enhance the performance of the underlined device, the mathematical model parameters are used in a reliable manner in such a way that the optimum behavior was achieved. These parameters play the central role in specifying the optical characteristics of the consid...

In this paper, we take the urban road network as the object, a further study on the method of traffic signal self organization under the condition of traffic state identification and local congestion. In the urban road traffic state identification study, according to the need of traffic signal control, respectively from qualitative and quantitative point of view, the urban road traffic state is...

Abstract Landslides occur due to instability in the soil triggered by vibrations, high rainfall and topographical conditions of an area. Landslide is a natural disaster that often occurs West Sumatra. This landslide certainly has impact on traffic around Congestion caused landslides falling chunks material onto road. Lack control during makes travel ineffective inefficient. Therefore, its possi...

The most important feature of Vehicular Ad hoc Networks (VANETs) is the high mobility of nodes, which makes the mobility model one of the most important parameters that should be carefully selected when evaluating any protocol. To correctly and faithfully evaluate protocols in a simulation study, the model should be as realistic as possible. Vehicles communicating wirelessly play an important r...
