Nevada adds dashcam data to digital twin of work zone traffic

The Southern Nevada’s Regional Transit Commission authorizes hundreds of work zones across five cities every day, but in order to monitor how the work affects traffic in real time, RTC has had to look elsewhere.

RTC has been pulling data from fixed cameras, traffic sensors and tracking RFIDs built into work zone traffic control elements into an Esri’s GIS platform to create a comprehensive digital model of civil engineering projects in Las Vegas.

Now, a partnership with Nexar -- best known for its dashcam technology -- will allow RTC to use data from Nexar’s CityStream platform, the company’s cloud-based digital twin service. Data from the company’s dashcams will help RTC’s digital twins show the real-time status of traffic patterns in the Las Vegas area, including the impact of work zones, changes in traffic signs and road quality.

“Leveraging vision, and in particular crowdsourcing from moving cameras roaming the cities, allows for a rich, live, and equitable digital twin that covers entire cities and not just high-traffic areas,” Nexar CEO Eran Shir told VentureBeat.

Esri, meanwhile, is working to improve workflow and allow more complex data conversion for digital twin applications. At its annual user conference in July, the company announced updates to its ArcGIS Velocity software for reality capture, plans for more indoor mapping and improvements in user experience design for digital twins.

In August, Nexar offered state and local transportation departments across the country three months’ of free access to its CityStream service, allowing them to pilot using dashcam data to show the real-time status of roadway work zones.
