A vehicle behavior control apparatus includes a rotary body formed as a part of a power plant installed in a vehicle, and a shaft deflection unit that sets a vehicle behavior target value for obtaining a target vehicle behavior, and deflects a direction of a rotary shaft of the rotary body relative to a vehicle body in accordance with the vehicle behavior target value. Additionally the paving block can also have a light-transmitting cover and a light-transmitting base on either side of the phosphorescent material to form a laminate. Each emergency lighting assembly has an emergency lighting component, a micro processor for controlling the operations of the emergency lighting component, a memory device for storing information of the emergency lighting component, a battery for providing electrical power to the emergency lighting component, and means for receiving and transmitting radio signals.
