摘要：PROBLEM TO BE SOLVED: To provide a travel control device and a travel control system can prevent occurrence of traffic congestion or reduce traffic congestion by travel control of a vehicle. SOLUTION: The travel control device obtains a traffic state including a vehicle density for each lane of a road on which a vehicle travels (S10), changes the lane of the vehicle to a lane having a higher vehicle density among the lanes (S18 to S26), and performs travel control to the vehicle that changes the lane to a lane having a higher vehicle density so that an inter-vehicle distance is hard to become shorter as the vehicle density approaches to a critical density (S28). Thereby, changing the lane of the vehicle to a lane likely to be congested can suppress occurrence of traffic congestion or reduce traffic congestion. COPYRIGHT: (C)2010,JPO&INPIT
