These research led us to various conclusions supporting the positive environmental impacts of a large scale deployment of the AM model
Low impact of the automation required equipment
The production of components required for automation and their total energy use do not significantly affect overall environmental impact.
The Automated Minibuses externalities estimations demonstrate positive results for introducing them particularly when replacing some individual forms of mobility.
Automated Minibuses (AMs) have high energy saving potentials: the consumption increases linked to the vehicle automatization’s required equipment functioning (and its weight and drag) is way lower than the energy saved through eco route planning, traffic light assistant, predictive adaptive cruise control or eco-driving, thermal management and hybrid&fuel cell control, connectivity, fleet operations optimization, etc.
The AM service global energy consumption performance (and related environmental impact) depends on its integration within the PT, as well as how widely it will be deployed.
High energy efficiency and reduction in local air pollution
Our environmental indicators reveal that the energy efficiency and the reduction in local air pollution (no direct GHG emissions) are Automated Minibus services’ strong points.
Our demonstrators climate impact promising results
Despite the pilot testing’s particular circumstances, our demonstrators Automated Mininbuses’ climate impacts are lower than diesel buses and individual ICEVs and according to our use cases AMs will soon be performing better than all other transport means at off-peak and all individual vehicles on average.
Our Lyon and Luxembourg demonstrators present an excellent climate change indicator rating as a result of a high mileage and average occupancy. This high average occupancy also guarantees a good energy efficiency score to these sites. Copenhagen and Oslo have the best score for the renewable energy indicator among our sites.
AM impact on the mobility demand and trip distribution
The Automated Minibus (AM) advent will have an important effect on the mobility demand and the trip distribution.
AMs are expected to improve and strengthen public transport, hence bring environmental benefits by reinforcing shared, multi and intermodal mobility as well.
How to even improve the AM environmental performances?
Decreasing the most polluting phases impact
An Automated Minibuses (AM) life cycle climate effects analysis has shown that the production of the components and the driving itself are by far the most environmentally intensive phases of the AM life cycle. The component production/manufacturing dominate our demonstrators’ climate impacts but the use phase will soon be the first impact contributor.
Reducing the most environmentally impacting parameters
The sensitivity and scenario analyses show that the parameters that influence the Autonomous Minibuses environmental impact the most are the electricity mix used, the AM lifetime/mileage and average occupancy, followed by the battery production mode type and the use phase energy efficiency.
An AM with an ideal mileage and occupancy rate is environmentally better than any other transport modes.
