Welcome to Springfield.

The world's first large scale, multi-use driving simulation environment.

Urban. Suburban. Rural.

Springfield contains over 230 linear miles of roadway complete with realistic signs, traffic signals and lane markings. At the flip of a switch, the city can be driven at specific times of day and specific lighting conditions. We have control over the weather and road conditions and are able to simulate dry, wet, icy and snowy weather.

In short, Springfield has been designed to replicate the driving experience of virtually any city, in any time of the day and in any weather condition.


Easily modified to suit any application

Unlike the real-world locations that Springfield is inspired after, it’s easy to make changes to this city to suit changing needs.

It’s possible to control traffic, orchestrate pedestrians, add signs, change building facades, adjust lane markings, adjust road surface properties, or even add new roads and intersections.

Springfield will enable the simulation of complex traffic events leading to a better understanding of connected and automated vehicle technologies.


Springfield Stats

What makes Springfield so unique?

A vast driving environment, larger than Chicago
Easy to change and customize
Complete control over time of day, weather and road conditions
Complete control over other traffic and pedestrians
Ability to orchestrate complex events that can be accurately replicated again and again using different drivers and vehicles

Among the 230 miles of roadway, Springfield already contains these areas:


Springfield has realistic traffic consisting of cars, trucks, motorcycles, bicycles, and various utility and service vehicles. Traffic of varying densities can be created around the driver. Individual vehicles in the traffic can be commanded to maintain specific headways and following distances. By default, traffic follows the rules of the road and fully reacts to the driver. Individual vehicles can also be commanded to break the rules of the road by speeding, running traffic lights, turn without signaling, etc.


Springfield has realistic pedestrians that walk along sidewalks and crosswalks. Pedestrians can also been commanded to cross roads and interact with vehicle at specific times and distance. This enables simulation of complex interactions between pedestrians and vehicles. It’s possible to specify the gender, age group and clothing for each pedestrian.
