This paper presents the possibilities of validating the microscopic traffic flow simulation model VISSIM, both on a microscopic and a macroscopic level. VISSIM implements a psycho-physical carfollowing model and thus provides a very realistic driving behavior. The complex model offers but also requires many model parameters that can be calibrated using measurement data from driving experiments....

Bus Rapid Transit systems have grown in popularity in recent years. With the rapid development of computer technologies, using microscopic simulation models to study various strategies on planning, implementation and operation of BRT systems has become a hot research area in the field of public transportation. To make the simulation models accurately replicate field traffic conditions, model ca...

As part of the Central Phoenix/East Valley Light Rail Transit Project, the Cities of Phoenix, Tempe and Mesa, Arizona are proposing a new light rail line, part of which will follow Central Avenue, a major north-south corridor in the City of Phoenix. The service is expected to initially operate with approximately 6-minute headways in both directions. The LRT tracks will be in the center median a...

The paper describes the questions of decision support system in transport planning. One of the methods used for studying the relationships and underlying the transportation decision-making is transport modelling, which includes traffic modelling on micro and macro levels. The research considers the example of the microsimulation model of Riga complex transport node. At first, the simulation mod...

This paper presents how an optimal optimization method, Genetic Algorithm (GA), is applied for finding a suitable combination of VISSIM parameters. The North-South (NS) Expressway is investigated and simulated in VISSIM platform using field data obtained from Traffic Information Collecting System (TICS) in Shanghai. Numerous simulation tests indicate that the following main parameters have affe...

The simulation of vehicular traffic as well as pedestrian dynamics meanwhile both have a decades long history. The success of this conference series, PED and others show that the interest in these topics is still strongly increasing. This contribution deals with a combination of both systems: pedestrians crossing a street. In a VISSIM simulation for varying demand jam sizes of vehicles as well ...

The work discussed in this paper consists of a statistical assessment of various finite difference schemes for approximating macroscopic models of traffic flow. Using VISSIM we simulated traffic flow on a section of a freeway with arbitrary characteristics. VISSIM is a traffic flow simulator that uses a microscopic model for traffic. By using data from a microscopic simulation, we are able dete...

In this thesis a modular code skeleton for combining Variable Message Signs (VMS) and Adaptive Cruise Control (ACC) as a combined system are being presented. Basic control theory for the two control types are given with corresponding pseudo code. Also simulation with the different controllers are compared and discussed. Finally some tips and tricks regarding the simulation software VISSIM are g...

Original scientific paper Urban road intersections are bottle-necks of urban road networks, and the traffic organization optimization of intersections is the crux to relieve urban traffic jam. After analysing the features, applicable conditions and functions of the intersection channelization design, the basic procedures based on traffic survey, channelization design of the intersections and as...

In this contribution first results of experiments on pedestrian flow through bottlenecks are presented and then compared to simulation results obtained with the Social Force Model in the Vissim simulation framework. Concerning the experiments it is argued that the basic dependence between flow and bottleneck width is not a step function but that it is linear and modified by the effect of a psyc...
