Cities Looking to Automated Vehicles to Solve Congestion and Emissions Challenges

Ryan Citron — November 21, 2017

Around the world, major cities have been setting targets to combat the negative effects of local transport on public health, local pollution, noise levels, and greenhouse gas (GHG) emissions. Cities are looking increasingly at the potential of automated vehicles (AVs) to help solve these problems through improved traffic flow, the near elimination of collisions, increased productivity, and reduced pollution and GHG emissions.

 Moving toward Full Automation

The concept of automated or self-driving cars has shifted from the realm of science fiction into reality, as showcased by some of the latest developments in cities around the world:

 Key Challenges Remain

Partial automation is becoming commonplace in all road vehicle classes. Full driving automation is starting to be piloted in numerous cities globally with regular commercial deployments expected in the next 2 to 3 years. Before AVs can become ubiquitous in city streets, new infrastructure investments, communication network upgrades, the need for fleets to operate in varied conditions, and concerns about cybersecurity need to be addressed. Cities also need to develop frameworks to integrate and coordinate AV mobility services with existing transit services to optimize the use of road infrastructure and avoid increased congestion. Although the AV was not at fault for the accident, the recent Las Vegas automated shuttle collision shows why vehicle-to-vehicle communications will also be crucial to the success of AVs.

If AVs are managed properly, highly integrated with public transport, and coordinated as part of a multimodal transportation ecosystem, the shift to self-driving vehicles could lead to reduced traffic congestion in cities, lowered demand for parking spaces, and highly beneficial energy and environmental effects. For more information on the potential effects of AVs in cities, see Navigant Research’s recent white paper on Redefining Mobility Services in Cities.
