What type of data can Lidar systems collect apart from speed?

Lidar systems are capable of collecting a variety of data points besides just speed. The correct answer highlights that Lidar can gather information on vehicle size, location, and distance.

Lidar technology works by emitting laser beams to measure the distance to objects. This capability allows it to accurately determine not only how far an object is (distance), but also to assess its size by analyzing the return signal of the reflected waves. Furthermore, with corresponding geographical information systems, Lidar can precisely plot the location of vehicles in relation to their surroundings.

While distance is a key component of what Lidar measures, it is the combination of vehicle size and location that provides a more comprehensive understanding of the environment and enhances traffic analysis. Other options include aspects like weather conditions or specific vehicle attributes such as color but these do not align with the primary data capabilities of Lidar systems. Hence, the answer that encompasses vehicle size, location, and distance reflects the multifaceted data collection abilities of Lidar technology.
