release valve

we've made an inflatable speed bump and hooked it up to the sensor so when a vehicle arrives at a certain distance, the pump will activate if the car is going too fast.. but.. I'm unsure if it's possible to have it connect to the same sensor and use plc to open some sort of valve to release the air after the car goes over the bump. Does anyone have any better ideas of how to deflate the contraption..? Thanks.

    A two position valve. Power off, position one, bump deflated. Power on, position two, bump inflates.
