1 Mixed traffic, characterized by diverse vehicles, changing composition, lack of lane discipline, etc. is best modeled 2 by micro simulation. However, the majority of the leading micro simulation packages and their calibration 3 methodologies have been developed considering less complex homogeneous traffic. Hence, a methodology for 4 calibrating a micro simulation model for mixed traffic is pr...

This paper focuses on traffic simulation generated by the multi-agent simulation framework TRASS (Traffic Simulation System). TRASS-based simulations conceive agents as individual traffic participants moving in an artificial environment and which can be described in a three-layer agent model. There is no restriction on any particular kind of road users such as cars or pedestrians, but a concept...

This paper presents a simulation framework incorporating traffic simulator with classical discrete event simulation model of internal transport systems. The objective behind this integration is to provide a simulation model in which traffic is captured in the internal haulage networks. For this purpose, the highly detailed microscopic traffic modelling approach is adopted. The developed simulat...

There is a growing need for improvement in the efficiency of urban traffic in order to ensure the sustainability of modern cities. It is now recognized that this can be achieved through the coordinated improvement of traffic monitoring and management schemes in traffic control centers and the provision of information services for ordinary road users. The real-time (on-line) simulation can have ...

Keeping the density of traffic flow and air pollution in an acceptable level and developing a good capacity for transit in the high priority areas of the city, is really a big deal in large and crowded cities. To address this problem, a new method of intersection signal optimization is presented in this paper. Based on network fundamental diagrams, an Internal–External Traffic Metering Strategy...

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...

This paper presents the simulation of traffic flow on a congested street in the Jordanian capital Amman. The geometry, boundary conditions and assumptions were also compared against videos taken for actual traffic on the street. Although limited changes to the geometry is applicable in reality, some recommendations on speed limits and traffic signs were made to aid in reducing traffic jams. Key...

The aim of this study is to investigate the problems caused by discharge of polluted air from tunnels into the environment with a specific focus on residential areas. In city tunnels, portal or stacks, pollutant management is a big challenge. Nowadays, air quality management, particularly in urban tunnels, is considered as a part of the ventilation system design. The goal is to see the environm...

In this study a framework for developing an object-oriented tool –DRONE (areawide Dynamic ROad traffic NoisE simulator) to generate areawide noise contour maps for a road network is demonstrated. This provides faster access to information for abatement of noise policies. The approach for integrating the dynamic output from traffic simulator to noise model, which predicts traffic noise based on ...
