A travel control apparatus includes: a transformation unit configured to project the lane and object on a lane coordinate system in which a center line of the lane is a first coordinate axis and an axis orthogonal to the first coordinate axis is a second coordinate axis by performing a coordinate transformation based on the shape of the lane and the position of the object in a plane coordinate system; an area calculation unit configured to calculate a travelable area in which the vehicle can travel in the lane coordinate system; a travel trajectory generation unit configured to perform an inverse transformation of the coordinate transformation by the transformation unit based on the travelable area, and to generate a travel trajectory of the vehicle in the plane coordinate system; and a control unit configured to perform a steering control on the vehicle.
