Techniques to provide guidance to a vehicle operating in an environment may include determining a suggested region to block in the environment along a path of the vehicle and causing presentation of the suggested region to block in a user interface of the computer device. Information about the blocked region may be transmitted to one or more vehicles in the environment. Based on the information about the blocked region, at least one of the computer device or a vehicle computer system of the vehicle may control operation of the vehicle to avoid the blocked region.
