Aimsun - A Siemens Company
Aimsun is a leader in traffic prediction software and services. Aimsun’s fully integrated software packages, Next and Live, complement the Siemens ITS portfolio by simulating future traffic flows to aid offline strategic transportation planning and real-time mobility management. From the engineering and implementation phase right up to daily operation, traffic engineers and system operators can rely on top-of-the-range tools for planning, data supply, administration and operation of their traffic control systems.
Aimsun Next software allows you to model transportation networks small and large: from a single intersection to an entire region. You can use Next to build a digital twin of a city or highway, then simulate the trips that people want to make, and match them with the available transportation options such as taxis, buses, car-shares, bikes or even walking. Digital modeling is a safe and cost-effective way to experiment with different designs or operations plans and help make places safer, cleaner and more livable. Over 5,000 professionals in 82 countries around the world use Next software to plan the future of our cities.
Benefits and Highlights
Aimsun Next can simulate entire cities much faster than real time: A microscopic model of Singapore can run 2-3 times faster than real time on a normal laptop. The meso model is 4-6 times faster still. For large models, this difference is make-or-break. For smaller models, it allows for more ‘what if?’ scenarios, iterations and sensitivity analyses with the same time budget.
Aimsun Live finds patterns in historical traffic data and combines them with real-time data feeds from sources such as road cameras, satellites and our phones, to build an accurate picture of likely upcoming traffic conditions. It’s so fast that within a few minutes, traffic control room operators can test and deploy the best strategy for avoiding upcoming congestion. Government organizations in the USA, UK, France and Australia use Aimsun Live to work towards smart highway systems and truly connected cities. Aimsun Live slots right into the traffic control center and continously processes live field data, simulating vehicle movement inside a road network of any size, from a single highway corridor to an entire major world city.
Benefits and Highlights
Simulation can significantly improve the accuracy and relevance of travel-time forecasts. Because it takes capacity changes and network effects into account, it is the only technique that can allow operators to compare the effectiveness of complex alternative traffic management strategies quickly and objectively.
One of the key elements that makes Aimsun Live a unique solution for real-time forecasting and information provision is its rich and innovative combination of dynamic traffic assignment (DTA) techniques within the same simulation to give the most realistic representation possible of network behavior.
