SimulationEngine MultiCoreCPUSimulationEngine GPGPUSimulationEngine Figure 5: Simulation engines in SIMILAR 2.6 Probes The observation of the data of the simulation is managed using probes. Probes are objects listening to the evolution of the state of the simulation. Since the state of the simulation is not always consistent (especially during the computation of the reaction), the probes do not...
متن کاملSpace-time modeling of traffic flow
This paper discusses the application of space–time autoregressive integrated moving average (STARIMA) methodology for representing traffic flow patterns. Traffic flow data are in the form of spatial time series and are collected at specific locations at constant intervals of time. Important spatial characteristics of the space–time process are incorporated in the STARIMA model through the use o...
متن کاملModeling and simulation of traffic flow
Recently, investigations of empirical traffic data revealed a variety of phenomena, e.g., metastable states with a very high flow and synchronized traffic flow with a sudden drop in the velocity. In this paper we present a survey of the progresses made in modeling and understanding the dynamic traffic phenomena. 1999 Elsevier Science B.V. All rights reserved.
متن کاملTraffic Data and Their Implications for Consistent Traffic Flow Modeling
The paper analyzes traffic data with respect to certain aspects which are relevant for traffic flow modeling as well as the calibration of model parameters and functions. Apart from the dynamic velocity distribution, the density-dependence and the temporal evolution of various, partly lane-specific quantities is investigated. The results are well compatible with recent macroscopic traffic flow ...
متن کاملModeling traffic flow interrupted by incidents
A steady-state M/M/c queueing system under batch service interruptions is introduced to model the traffic flow on a roadway link subject to incidents. When a traffic incident happens, either all lanes or part of a lane is closed to the traffic. As such, we model these interruptions either as complete service disruptions where none of the servers work or partial failures where servers work at a ...
