Case Study: Smart Intersection

Application Name:
Smart infrastructure monitoring and analytics using LiDAR, camera, and radar sensors.
2D, 3D, and 4D visual sensors enhance safety by monitoring the behaviors of mobility users and providing analytics at intersections, arterials, highways, and toll roads along critical infrastructure.

About Sensagrate
Sensagrate is a computer vision software company that provides traffic AI solutions on the edge to bring state-of-the-art innovation solutions that provide real-time, predictive analytics data to decrease congestion and emissions and improve public safety. SensaVision intelligent transportation system (ITS) products include computer vision software, computer vision on the edge, and traffic and safety data and analytics.

The Need
​Approximately 1.3 million people die each year as a result of road traffic crashes. More than half of all road traffic deaths are among vulnerable road users: pedestrians, cyclists, and motorcyclists (WHO). SensaVision addresses pedestrian fatalities by utilizing infrastructure to monitor the movements and incidents between vehicles, pedestrians, and cyclists to optimize the environment with data-driven design and awareness. By making roads safer and smarter, there is also the opportunity to reduce the environmental impact caused by traffic jams, idling, and other inefficiencies caused by non-smart infrastructure.

The Challenge
Safety is hard to ensure both on the roads and for vulnerable road users. One step towards improving safety is by building safer infrastructure based on real-time, proactive, and predictable data and analytics. Data collection can be limited because of a lack of adequate equipment. Once sensors (e.g., LiDARs, cameras, RADARs) are installed, the city becomes “smarter and safer”. These sensors can accelerate this digitization by providing a sensor that is resilient to weather and environmental conditions. It provides the high KPI that is necessary for planning, implementation, and navigation decisions that have lives at stake. Moreover, the data collected must adhere to privacy and equity standards. 

The SensaVision Solution
Camera, Radar, and LiDAR sensors are deployed into a “smart intersection corridor”. The sensors are installed on existing infrastructure, connected to the SensaVision Edge solution combined with Sensagrate’s SensaVision perception software and analytics, providing real-time data on traffic volume, near-miss collisions, counts of mobility objects, and other roadside safety metrics. Combined, the sensors provide a higher accuracy in detection, and the range allows for advance warnings and accuracy data to optimize traffic congestion and improve safety.

Customer Benefits
The sensors have different advantages relative to each other but complement each other, requiring no gaps in any adverse weather conditions, allowing the sensors to provide detection during rain, dust storms, fog, and snow. Analytics gather data, while promoting pedestrian, automobile, and other vulnerable road user safety by optimizing traffic design and flow. This is done by collecting data for root cause analysis of pedestrian-related incidents (or near-miss collisions) through intelligent data collection and predictive analytics.
