LiDAR Traffic Signal Detection System
The LiDAR traffic signal detection system project helped a local agency upgrade traffic detection at key intersections. In this deployment, the city sought to improve detection accuracy, safety, and responsiveness. Therefore, modern LiDAR technology was selected, resulting in signal timing and vehicle presence data becoming more reliable.
Because detection affects how signals respond, the agency needed a system that could handle high‑speed and multi‑lane environments. Moreover, the goal was to support better timing decisions while improving safety for all road users, including pedestrians and cyclists.

- Better data for analysis and future timing plans
LiDAR detection helped the agency gain precise vehicle presence data, which improved signal decisions across complex intersections.
Project Overview
The agency needed a detection system that could accurately sense vehicles in all lanes and at high speeds. Older detector types sometimes missed vehicles or created false calls. Consequently, signal timing plans were less effective. Therefore, the agency selected LiDAR detection to improve accuracy and performance.
LiDAR uses laser pulses to measure object distance and movement. Because this technology captures detailed traffic presence data, it can detect vehicles even in challenging traffic conditions. In addition, it can sense small objects and slow‑moving vehicles with greater precision than older systems.
Deployment and Integration
Econolite supported the installation of LiDAR detectors at selected signal approaches. First, site surveys identified the best mounting locations. Next, the LiDAR units were connected to existing signal controllers. Then, detection zones were configured to match traffic patterns. Finally, calibration ensured accurate vehicle presence and movement reporting.
Once installed, traffic engineers could view reliable detection data at intersections. Moreover, enhanced detection fed into signal timing algorithms. As a result, signals could respond more accurately to real time traffic conditions.

Operational Benefits
The LiDAR traffic signal detection system provided several operational advantages. For example, detection accuracy improved significantly. In addition, signals responded more quickly to changes in demand. Therefore, travel delays decreased for motorists. Moreover, pedestrians and cyclists benefited from fewer conflicting movements. As a result, the overall intersection performance became more predictable and reliable.
