Traffic Prediction

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. 

Integrated macro, meso and micro modeling levels allow you to gradually extend your model’s boundaries without having to change your software or sacrifice speed – thanks to the hybrid simulator you can zoom in and out at will, seeing close-up detail only where you really need it.

Store and compare multiple geometries and scenarios in a single file, eliminating menial copy-paste tasks and unmanageable file libraries.

Customize your models: build API extensions in C++ or Python, override behavioral models with the microSDK, and build your own plug-ins with the platformSDK.

Aimsun Next’s dynamic traffic assignment (DTA) scheme gives you the option to model steady-state behavior as well as react to non-recurring scenarios. This is particularly important in corridor models and in large urban models where calibration of microsimulation assignments can be tricky.

An all-in-one model means a single payment for maintenance, training and support. It’s also faster to learn and faster to use, with no error-prone manual interfacing between different software packages. 

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.

Unlike traditional analytical forecasting processes, a simulation of individual vehicles permits an explicit and faithful emulation of ITS policies.

With access to individual vehicle delays, travel times, position, pollutant emissions, speed, route and many other characteristics, the measures of effectiveness can be as complex as needed.

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.

To ensure the best possible forecasting accuracy, Aimsun Live includes a module that continuously compares forecast performances against field measurements received once the prediction period has passed.
