On-vehicle images provide a comprehensive and current view of road infrastructure conditions

The rise in autonomous driving is forcing transportation agencies to commit more resources to monitoring the quality of roadway infrastructure. Pavement quality, lane line paint and markers, and objects along the road can all affect the performance of autonomous driving systems and the safety of road users. Understanding when and where these features are degrading is vital for maintaining an ecosystem sufficient for these emerging technologies to operate in. Resources are limited, so transportation agencies need to efficiently assign maintenance crews.

Monitoring the roadway with on-vehicle images

Vizzion’s network of tens of thousands of connected commercial vehicles equipped with professionally-mounted HD cameras is a cost-effective way to monitor the roadway. Instead of relying on the public to submit inaccurate reports in an untimely manner, Vizzion’s cameras provide ground-truth information on-demand. Sending out crew members to collect first-hand reports and evidence of deterioration can be costly for transportation agencies. Vizzion’s service eliminates overhead expenses like fuel and frees up staff to complete other tasks.

Cameras in commercial vehicles offer a solution superior to consumer dash cameras

Professional grade cameras mounted in commercial vehicles offer advantages over crowdsourced consumer dash cameras. The vehicles follow similar routes day over day, allowing images from the same location to be collected and compared. Different road types are traveled by the fleets, making our service a well-rounded solution for both municipal and state level transportation agencies. Compared to consumer vehicles, commercial vehicles are on the road 5 times longer each day. The viewpoint continues beyond other vehicles as the images are captured from a higher vantage point. Images are submitted to Vizzion by the vehicles over cellular connection, allowing for both historical and real-time review of the roadway.

Vizzion’s Commitment to Quality

Consisting of a suite of automated tools and manual processes, Vizzion’s quality procedures ensure that transportation agencies can have confidence that all on-vehicle imagery they receive is helpful. New camera installations are manually reviewed and placed on a whitelist to ensure only useful viewpoints and imagery are provided to the end users. Computer vision-based algorithms are used to filter out poor-quality images. Other automated services consider where the vehicle is on the road network, which helps to prevent images from being captured when the vehicle is off the roadway or is stopped at an intersection. This eliminates the exposure of Personally Identifiable Information. Images sourced from connected commercial vehicles are a rich source of data, and ensuring their usefulness for maintaining road infrastructure for autonomous vehicles is worth the automated and manual resources.
