为您指定的城市定制全尺度交通仿真软件(FSTSS-YC: Full-Scale Traffic Simulation Software for Your City)

The Main Features of FSTSS-YC:

* Versatile multi-line source Gaussian dispersion tool with the urban scale for simulation, prediction and analysis; the leading technique of the product embodies in his advanced mathematical model and innovation algorithm, based on a series of famous multi-line source models in the world and improved greatly by ESDV, which can be used in cities, where the values of surface roughness factor Z0 for representative land use types are frequently variable. The software consists of computing engine, surface roughness factor Z0 file(s), high quality Graphical User Interface, self-contained map support system, computed results’ visualization tool and analyzer as well as help system, and can be used in a variety of Windows-based microcomputers.

* Through dialog boxes, tables and simple operations on digital maps to input the data about road positioning and traffic parameters, meteorological parameters and receptors’ disposition, etc.; perfect display, correction, printing and storage functions for entered data.

* User-friendly and powerful map support tool forpre- and post-processing, including map basic color inspection, geometrical data collection and auto-inserting to tables (road positioning), receptorarrangement, digital map background, map enlargement, shrink, storage andprinting, etc..

* Practical maker for generating surfaceroughness factor Z0 file(s) through clicking on gridding digital map, andfunctions to store, display, correct and build up the produced files.

* Up-to-date visualization technology ofcalculated results can generate 2 and 3D pollutant concentration fielddistribution graphics with and without map background. The 2D view providesthree concentration contour displays (homochromatic, color and color filledimages) and the 3D view provides 6 types ofgraphics (black balls, color balls,black wires, color wires, color surface and color surface-wires), which can rotatearound Z axis (vertical axis). The user can display, store, print and analyzecomputed results without the help of any commercial cartographic software.

* Easy to use results’ analyzer, which functionsinclude point-by point display of mouse coordinates and model-calculatedconcentration value (point analysis), and display and analysis of variouscharacteristic concentration values within a towed rectangular region (regionanalysis, to display the maximum, minimum and mean concentrations as well asdetailed analysis table under a certain and all wind directions for currentcalculation).

* Once calculation can quickly simulate, predictand analyze the pollutant concentration values at several designated points ordistribution field at a certain height, caused by motor vehicle exhaust gasemission in urban areas.

Uses:

1. Reliable tool for simulating, predicting, analyzingand comparing the inert pollutant concentrations at given spatial points andconcentration distribution fields at certain heights, caused by motor vehiclesexhaust gas emission in city-scale region, without the restriction for thereceptors only located in a long and narrow strip region within 150 meters ofthe roadway. In other words, SPS-YC’s advanced mathematical model has discardedthe so-called ‘micro-scale region’ restriction, where the surface roughnessfactor Z0 should be a constant only, widely adopted by current vast majority ofmulti-line source modeling tools in the world, used commonly to assess trafficpollutions.

2. Excellent researching, assessing and teachingsoftware tool for the projects and courses, related to air quality in yourcity/region.
