Most traffic lights tuning today cannot handle real-time
load fluctuation due to lack of queue time
detection (how long it takes for cars to cross a
junction). Video cameras provide operators with indication
of queue time to some extent, but the high
installation costs involved prevent an adequate coverage of
all problematic junctions. Minimizing the total queue
time in a junction provides the best optimization of traffic light
tuning. Cellint has developed SmartLight - a revolutionary
solution providing real-time highly accurate queue time, at order
of magnitude lower cost, enabling efficient tuning of traffic
light in real time! SmartLight automatically provides traffic
load data and tuning alerts, thus eliminating the need for
human operators to continuously watch cameras and make
decisions based upon partial information only.
Cellint�s customers include leading ITS integrators,
transportation departments and municipalities.
Cellint extracts traffic data on any junction from
cellular networks using Cellint�s state-of-the-art
VirtualSensor technology.

SmartLight System SmartLight system simulates road sensors throughout the roads that enter and exit the junction, measuring queue time for all junction�s directions at higher resolution and significant lower cost than any other system, including video cameras, inductive loops or acoustic sensors. By automatically analyzing queue times on all junctions� directions, the SmartLight System provides a complete solution for traffic light tuning. The system automatically alerts on problematic situations and suggests alternative traffic light settings to the operator. Based on queue time statistics in each direction accumulated by SmartLight continuously, the system enables periodical calibration and optimization of the traffic light programming. SmartLight incorporates all aspects of Cellint�s comprehensive traffic data solutions:
