Video Detection
Video detection solutions were introduced into the traffic signal industry in the late 1990’s and is today the most common alternative solution to inductive loops. Video detection technology varies by equipment manufacturer with systems using methods such as pixel image change to identify objects, tracking to validate object movement, and thermal cameras to improve detection during inclement weather.
Regardless of the technology, all video detection solutions now offer bicycle differentiation algorithms and pedestrian detection algorithms are slowly being introduced.

Econolite
Econolite is one of the two early pioneers in video detection technology for traffic signal operations. Econolite distinguishes itself from other systems through the use of tracking technology and the use of on-board computer processors embedded within their field cameras. Field cameras communicate with traffic signal cabinet hardware using proprietary 3-wire system but also support Wi-Fi connectivity for quick setup and programming. Econolite offers several video detection solutions, to learn more, visit the Econolite website.

Flir
FLIR is a newer player in the video detection marketplace for traffic signal control. FLIR acquired long-term video detection player Traficon in 2012 to combine their thermal-based image sensors with too offer a completion intersection detection system. The FLIR systems works well in applications where inclement weather or unusual obstructions such as tree canopies impact traditional camera views.
FLIR offers a robust number of detection solutions but consider this system for use with dedicated bicycle cycletrack operations for improved bicycle detection. To learn more about FLIR detection system, visit the FLIR Website.
Gridsmart
Gridsmart is the newest player in the video detection marketplace and they were acquired by CUBIC in 2019. Gridsmart is unique from the other video detection systems in that it uses a single fish-eye camera to monitor an intersection versus the one camera per approach of traditional systems. For large intersections a second fish-eye camera can be added. Gridsmart was an leader in integrating the video detection system with the real-time traffic signal status of the intersection (Red, Yellow, Green, Walk, Don’t Walk) and their acquisition by CUBIC promises to introduce more advanced traffic signal timing and traffic flow strategies.

Iteris
Iteris is the other early pioneer in the use video detection for traffic signal operations. Iteris detection systems use pixel differentiation to identify objects and they were early leaders in bicycle differentiation detection. Traditional Iteris systems used analog cameras while their newer solutions take advantage of IP-based cameras that communicate back to traffic signal cabinet equipment over standard ethernet cables. Iteris is advancing their Intelligent Transportation System (ITS) solutions by expanding data from their video detection systems to offer Signal Performance Measure (SPMs) data anlysis. Iteris also integrates their video detection system with their Bicycle Detection Indicator system.
