In recent years, the transport simulation of large road networks has become far more rapid and detailed, and many exciting developments in this field have emerged. Within this volume, the authors describe the simulation of automobile, pedestrian, and rail traffic coupled to new applications, such as the embedding of traffic simulation into driving simulators, to give a more realistic environment of driver behavior surrounding the subject vehicle. New approaches to traffic simulation are described, including the hybrid mesoscopic-microscopic model and floor-field agent-based simulation. Written by an invited panel of experts, this book addresses students, engineers, and scholars, as well as anyone who needs a state-of-the-art overview of transport simulation today.

Tools to evaluate networks under information supply are a vital necessity in light of the systems being implemented as part of the Intelligent Transportation Systems (ITS) deployment plan. One such tool is the traffic simulation model. This report presents an evaluation of the existing traffic simulation models to identify the models that can be potentially applied in ITS equipped networks. The traffic simulation models are categorized according to type (macroscopic, microscopic or mesoscopic), as well as functionality (highway, signal, integrated). The entire evaluation is conducted through two steps: initial screening and in-depth evaluation. The initial step generates a shorter but more specific list of traffic simulation models based on some pre-determined criteria. The in-depth evaluation identifies which model on the shorter list is suitable for a specific area of ITS applications. It is concluded from this research that presently CORSIM and INTEGRATION appear to have the highest probability of success in real-world applications. It is also found that by adding more calibration and validation in the U.S., the AIMSUN 2 and PARAMICS models will be brought to the forefront in the near term for use with ITS applications.

Statistical validation of simulation models has much interest in military applications. In particular, there is interest in transportation problems during emergency and standard situations. However, collection of suitable data is difficult and almost necessarily is limited to standard situations. Such a situation is examined in this paper. Vehicle traffic on a section of a freeway (expressway) near an on-ramp is simulated by a Monte Carlo model. Ability of the model to represent actual traffic flow is investigated by observing operational systems and making comparisons with results from corresponding simulations. Measures of effectiveness are used that compare statistics for operational systems with values of these properties for corresponding simulations (to see if the difference is significant). Separate comparisons are made for three kinds of statistics: (1) Average travel times for vehicles entering on the freeway; (2) Average travel times for vehicles entering on-ramp; (3) Some averages of velocities. Two phases occur, depending on the data for operational systems. (Author).
