AtLink has created AtSim - a novel 3-D visualization & simulation platform designed to study and present construction and traffic management projects. AtSim takes a simulation-based approach, creating realistic digital models in a flexible environment to support the ever-changing nature of these projects. Our simulation technology provides an accurate, high-value, data driven output of information for review and visualization with real-time traffic.
AtLink is inspired by the evolution of advanced technologies and their application to modern traffic management systems. Taking advantage of the deep knowledge in 3D technology, and simulation, AtLink created AtSim. AtSim is based on the belief that in the future traffic simulations will require the ability to integrate traditional static estimation approaches with dynamic historical or live traffic data with environmental data (Terrain, elevation, lighting, etc.).
AtSim models and captures the entire network of roads, bridges, buildings, vehicles, traffic lights, road signs, lighting, pedestrians, etc. into a realistic representation.
AtSim assembles the complete network of 3D models into a realistic gaming engine. This provides the AtSim users the flexibility to navigate and travel the virtual world at ease. It gives the users the wings to fly around freely while observing the traffic flows or take a “1st person” view (as if sitting in a vehicle).
Users can also select a “1st person” view (as if sitting in a vehicle).
AtSim’s ITSE takes into account environmental factors to provide a more realistic simulation. AtSim integrates with external data sources to use historical or live traffic data in its simulation. This enables realistic simulations that can simulate traffic flow of a given date and time interval to be utilized in a user’s traffic study.
Using the Microscopic model with ITSE AtSim can identify problem areas in the traffic network for existing or proposed conditions. AtSim offers mesoscopic, microscopic, and nanoscopic simulation, all in a single unified real-time environment.
AtSim’s ITSE incorporates the following features:
AtSim can simulate the following traffic devices with real world control patterns:
AtSim has the capability to incorporate accurate floodwater mapping based on raster images of historical data. AtSim Hydro features include Flood Water pooling and traffic affect integration. Traffic integration includes slowing down, changing lanes, and stopping for areas of deep water. AtSim Hydro uses modifiable settings to control flood water traffic interactions, by default AtSim Hydro uses the current TxDOT safety recommendations.
