Benefit Summary HTML

A modeling experiment by researchers from the University of Santiago, Chile and the Technical University of Catalonia sought to understand the impacts of Connected and Automated Vehicle (CAV) adoption in urban spaces.

The mathematical model, based on a theoretical circular city structure, incorporated various projected impacts of CAV usage. These included a lowering of travel-cost, given the increased freedom of CAV users; increased average speeds and road capacity, given CAVs' platooning capabilities; and a decrease in operational costs, because of CAVs' increased fuel efficiency. The model used continuous approximations to understand the impacts of CAV adoption, considering simulated demand zones across the city.

A modeling experiment by researchers from the University of Santiago, Chile and the Technical University of Catalonia sought to understand the impacts of Connected and Automated Vehicle (CAV) adoption in urban spaces.

The mathematical model, based on a theoretical circular city structure, incorporated various projected impacts of CAV usage. These included a lowering of travel-cost, given the increased freedom of CAV users; increased average speeds and road capacity, given CAVs' platooning capabilities; and a decrease in operational costs, because of CAVs' increased fuel efficiency. The model used continuous approximations to understand the impacts of CAV adoption, considering simulated demand zones across the city.

The researchers analyzed the overall impact of CAV adoption by examining the total cost to users and agencies, as well as the total congestion level. Both were analyzed for various rates of CAV market penetration. The model found that while the total cost fluctuated for different values of market penetration, it overall decreased as penetration rates increased.

However, the analysis also found that congestion could increase relative to the current system for middling values of market penetration--particularly when between 20 percent and 50 percent of vehicles are automated.
