As autonomous vehicles and smart city investments continue their blistering growth, experts say it’s vital that these two connected juggernauts work in better synchronicity.

An article by IT Online discusses recent findings by the International Data Corporation (IDC) its report “Collaboration Between Automotive OEMs and City Leaders for Implementing Connected Car and Smart City Solutions.”

In the report IDC looked at the interplay between these two massively transformational technologies which are generating huge levels of investment.

Global spending on autonomous cars will reach $29.6 billion by 2017, while governments around the world plan to spend $16.5 billion on intelligent transportation systems in the same timeframe.

IDC says that private-sector leaders of connected car technology must better collaborate with state and local governments to develop further advancements in urban environments.

Specifically, IDC says these two factions must work together on developing solutions for such issues as urban congestion, environmental impacts, street safety, better vehicle design and more value-added services for citizens.

“Connected cars have reached critical mass, and their interaction with the transportation infrastructure within Smart Cities is ongoing,” said IDC report authors Heather Ashton and Ruthbea Yesner Clarke.

“Automotive OEMs and smart city leaders will need to work closely to ensure the continued development of, and support for, connected car capabilities and services such as vehicle-to-vehicle and vehicle-to-infrastructure communications that will increasingly include autonomous operations.”

But are smart cities projects tackling real problems?

IDC’s recommendations come amid reports that predict that annual revenues from smart city projects will grow to nearly $89 billion by 2025. Despite this spending most smart city initiatives, include smart transportation projects, are focusing on solving peripheral issues, with few big projects tackling core city problems.

Meanwhile, connected car technology is witnessing a global race between technology giants like Tesla, Google and traditional auto manufacturers to develop the category killing robot vehicle. Yet these proponents of autonomous vehicles are focusing more on the technical self-sufficiency of their cars in urban environments, and less on how they integrate into the larger fabric of the reconfigured smart city of the future.
