TransModeler provides powerful and flexible data input and editing functions. It supports remote sensing images in various formats, and provides a set of image coordination and import functions in parallel with Google Earth, which is convenient for generating roads and facilities of traffic simulation networks. The results of the simulation function are based on real geographical data and displayed in a real-time and dynamic way. The results can also be stored in WMV and other formats for future demonstration.
In addition, TransModeler also provides a GIS application development tool library (GISDK) for the secondary development of the system. Users can customize their own interfaces and expand their required functions. Due to historical reasons, there are two different micro-simulation software * * * with the same one.
The name "Paramics" Paramics was first developed by SIAS in 1986, and the subsequent development process was assisted by the staff of the parallel computing center of Edinburgh University. Paramics has been developed, sold and provided with technical support by SIAS and Quadstone since 1998. palace
The company's version is now called S-Paramics, and Quadrstone's version is called Quadstone Paramics.
Paramics won a series of awards after it came out, including:
. 1994 Paramics was reported in New Scientist magazine.
. 1994 EPCC of Edinburgh University and SIAS Company both won the Scottish IT Technology Transformation Strategy Award;
. 1995, EPCC of Edinburgh University and SIAS Company both won the Smithsonian IT Award in American computer field;
. 1998, Stephen Druitt, president of SIAS company, was awarded the title of' OBE' by the queen of England in recognition of his outstanding contribution in the field of traffic models.
(Note: Some of the contents discussed below are applicable to both versions, the British application is mainly applicable to S-Paramics, and the American application is mainly applicable to Quadstone Paramics. )
Paramics is a new computing tool for traffic engineers and researchers to understand, simulate and analyze the actual road traffic conditions. Paramics' real-time dynamic 3D visual user interface, the ability to micro-process a single vehicle, supporting multi-user parallel computing and powerful application program interface have attracted much attention in the traffic simulation software market since its release, and it has become the mainstream advanced software tool widely used in the academic and engineering fields in the traffic field. Until 2004, the latest version of Paramics was version 4.2, which can run on all commonly used computer systems. The operating system can be Windows9x/NT/2000/XP or UN IX. The hardware platform can be a PC or a SUN workstation. Paramics includes a completely parallel road resistance calculation module, which is used to complete the interactive road resistance calculation of large-scale road network. Theoretically, it can support 6,543,800 nodes, 4 million links and 32,000 regional road networks. It is outstanding in simulating infrastructure and congested road network. At present, it can simulate traffic signals, ramp control, detectors connected with speed change signs, VMS and CMS, vehicle road network information display equipment, vehicle information consultation, path guidance and so on. Path guidance policies can be defined by user API functions.
Traffic simulation
Paramics is a fully integrated software, which integrates simulation, visualization, interactive road network drawing, adaptive signal control, online simulation data statistical analysis, car-following, traffic control strategy evaluation, interactive simulation parameter adjustment and other functions. You can read the information of nodes and road sections from Saturn, NESA, TRIPS and other related traffic software. Paramics has been playing an important role in the micro-traffic simulation software market since the first commercial version of 1996 was released. Paramics released by Quadstone Company has been widely used in many countries in the world and plays an important role in traffic planning, management and decision-making. Britain is the birthplace of Paramics and one of the most widely used areas. Paramics is used by the British federal government to test the design of traffic networks and highways, evaluate traffic control strategies and exhaust emission levels, and study medium and long-term traffic planning and management strategies. In addition to the federal government, local governments in about 10 major cities also use Paramics to assist traffic management and public * * * systems. The University of California, Evan, uses Paramics to establish Evan network experimental base to study intelligent transportation system. In addition, many private consulting companies and academic institutions in the United States, including the famous Oak Ridge National Laboratory and the U.S. Department of Transportation, have adopted Paramics for corresponding project research. Other countries and regions that use Paramics include Australia, Argentina, Germany, Belgium, Denmark, Singapore, China, Hongkong and Taiwan Province Province of China. Urban Mixed Traffic Flow Microscopic Simulation System (FLOWSIM) is a set of simulation system based on China mixed traffic flow model. It has powerful traffic data processing ability and rich road network editing function, and can intuitively express the traffic flow, signal control and comprehensive service level of the road network. It is suitable for simulation evaluation of road network planning and design, traffic management and traffic organization optimization, traffic control system optimization design and intelligent transportation system benefit analysis.

Traffic organization and control simulation: signalized intersection, signalized intersection, ramp, roundabout control, etc. Simulate various traffic signal control strategies: regional control, trunk line coordination, timing signal control scheme, etc. Analysis and research of traffic planning: the influence of abnormal traffic conditions such as traffic planning management methods (such as channelization, one-way traffic and no traffic) and traffic accidents on road traffic. Simulate the influence of various traffic facilities on traffic behavior: lane limit signs, lane change signs, road signs, fixed and variable information boards, etc. Traffic simulation display: two-dimensional and three-dimensional simulation effects with multiple angles and windows vividly reproduce the traffic process. During and after the simulation, traffic simulation data can be output: traffic flow, speed, travel time, delay time and other statistical indicators. Service areas: government functional departments such as traffic organization and management at all levels, management and planning departments such as urban traffic and urban construction, research institutions such as scientific research institutes and universities, traffic consulting companies and professionals? The characteristics of the software are based on the traffic simulation models of mixed traffic flow in China: car following, lane changing and merging, collision-free model between vehicles, pedestrian crossing model, bicycle riding model and so on. The simulation model is calibrated and verified by the data collected in the field. There are Chinese and English versions, and the interface design is clear and easy to understand and operate; Independent intellectual property rights, regular product upgrades; There are professional traffic simulation model research and development and technical support teams in China to provide professional software operation and use training.
