Claim 0:
1. A method, comprising:
configuring, by a computing device, a threshold time interval for a light detecting and ranging (LIDAR) system coupled to an autonomous vehicle, the threshold time interval configured to permit the LIDAR system to, as the autonomous vehicle is moving, emit a first laser pulse and a second laser pulse within the threshold time interval and hit a vehicle on a roadway based on an expected velocity of the vehicle;
emitting, by the computing device, the first laser pulse using the LIDAR system, the first laser pulse being emitted at a first point in time;
receiving, by the computing device, a first signal reflected off of the vehicle on the roadway;
emitting, by the computing device, the second laser pulse using the LIDAR system, the second laser pulse being emitted at a second point in time within the configured threshold time interval;
receiving, by the computing device, a second signal reflected off of the vehicle on the roadway;
determining, by the computing device, a first time of flight information of the first signal;
determining, by the computing device, a second time of flight information of the second signal; and
determining, by the computing device, a velocity of the vehicle on the roadway based at least in part on the first time of flight information and the second time of flight information.
