Methods, systems, and devices for communication are described. Multiple beams having multiple coverage areas that cover an area-of-interest may be formed. Respective signal profiles may be measured for the coverage areas. Based on the measuring, a signal profile that satisfies a criterion relative to the other signal profiles may be detected. Based on detecting that a signal profile satisfies the criterion, a presence of a vehicle in the area-of-interest may be determined.
