Claim 7:
8. A device, comprising:
a light detection and ranging (LIDAR) system coupled to an autonomous vehicle;
a processor; and
a computer-readable medium including instructions that, when executed by the processor, cause the processor to perform operations comprising:
configuring a threshold time interval for the LIDAR system, 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 the first laser pulse using the LIDAR system, the first laser pulse being emitted at a first point in time;
receiving a first signal reflected off of the vehicle on the roadway;
emitting a second laser pulse using the LIDAR system, the second laser pulse being emitted at a second point in time within the configured time interval;
receiving a second signal reflected off of the vehicle on the roadway;
determining a first time of flight information of the first signal;
determining a second time of flight information of the second signal; and
determining 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.
