Guiding Disruption in Urban Mobility to Support the Low-Carbon Transition

Luke Rust, Head of Commercial Development at Immense Simulations has been investigating autonomous ride hailing services and he has written a piece on the part they can play in the low-carbon transition.

Urban mobility is reaching a tipping point. The UK government is being fined for illegal levels of air pollution while London remains the second most congested city in Europe and seventh in the world. In order to hit the UK’s carbon target, surface transport emissions must reduce by an average of 4% every year to 2030. However, decarbonising surface transport remains problematic due to limited powertrain options and, in 2015, related emissions increased by 2.1%!

Against this backdrop, urban transportation is primed for dramatic disruption. Continued rapid urbanisation, changing demographics, climate change and technology development are providing optimal conditions for change and ushering a potential urban mobility revolution. The fundamental disruptive entity may prove to be the fully autonomous vehicle (AV, level-5 automation) that has potential to disrupt the automotive, logistics and oil industries – alongside many others. Compounding rapid AV industry growth – evolutionary business models, artificial intelligence and substantial financial backing are driving the rapid rise of new mobility services from organisations such as Uber and Didi Chuxing, who envision a future of shared, autonomous fleets pressuring traditional taxi fleets, public transport and even private vehicle ownership with a low-cost service.

This forthcoming AV revolution is being undertaken with minimum policy or regulatory guidance and framed in positivist terms with the promise of high energy efficiency and low – even zero emissions. There is however potential for increased travel demand and urban sprawl combined with continued internal combustion engine use to have major negative energy and emissions implications.

My MSc study sought to assess the role of shared electric AV fleets in the UK mobility revolution and the implications of privately-backed ride-hailing companies developing them in the absence of effective climate regulation.

The research had two primary components:

Beta testing the market leading AV fleet simulation software to evaluate early policy-dependent energy and emissions impacts for a UK local authority;
Conduct interviews with academics, private sector actors and policymakers to explore possible AV deployment futures, understand the role for government and identify key priorities for policymakers to ensure AVs successfully support a low carbon transition.
The outputs of this work indicate that though there exists a significant opportunity for AVs to drive urban transport’s low carbon transition the following is relevant:

AV power trains should be electric, and regulation brought in to provide industry with the requisite targets. Transport and electricity policy must be developed in tandem to enable this;
Emissions mitigation is likely to be best facilitated by a well-structured, dynamic road pricing system across the UK surface fleet to encourage low carbon, efficient use of the road network;
The public sector should take a lead in procuring AV services to maximise road network efficiency, augment private AV fleets and increase transport capacity at times of peak network demand; and
Policymakers must have access to critical datasets which at present they are prohibited from acquiring, be equipped with better simulation tools and be empowered to employ novel policy instruments to ensure the AV revolution is realised in a climate compatible way.
