In this project, we report a study on the feasibility of using a driving simulator to investigate the effect of temporary rumble strips on the car/humans. This study is part of the project which investigates how to effectively use rumble strips to reduce vehicle speed and increase driver alertness when they enter a short-term work zone. To reduce costs and avoid safety hazards, it is highly beneficial to use a driving simulator to study rumble strip design and placements instead of completely relying on field tests. 

However, it is crucial to establish the validity and to understand the restrictions of using the driving simulator. In this project, a sensor mote equipped with accelerometers is used to characterize the dynamics when a vehicle drives across rumble strips in field tests. Based on the data acquired, the driving simulator is instrumented to simulate the motions caused by the rumble strip.

Here I successfully simulated dynamics similar to that of a car (as found in field tests) for relatively low speeds (25 miles / hour). However, for higher speed, due to the limited 2D movement of the driving simulator, the noise was more prominent than the simulation data. 

The results obtained for 10Mph are shown below -
