The ‘Lisbon Study’ reloaded: Data from Helsinki confirms benefits of shared mobility

Mobility in Lisbon: Public transport versus private cars.

Mobility as a Service (MaaS) is the right answer to cut emissions and congestion freeing up urban space for uses other than parking. The best results are achieved when all private car trips are replaced with shared rides.

Using data and focus group results from Helsinki, the latest study from the International Transport Forum (ITF) confirms the ground-breaking initial findings of the mobility simulations for Portugal’s capital. In Lisbon, 9 out of 10 conventional cars could become redundant if all trips in the city were carried out by shared fleets of self-driving vehicles. As a member of ITF’s Corporate Partnership Board, PTV Group co-organised this report, called the ‘Lisbon Study’. And based on its results, PTV developed their latest MaaS software suite to calculate, implement and operate MaaS fleets of autonomous electric vehicles.

Lisbon and Helsinki compared
The benefits of shared mobility for both, Lisbon and Helsinki, are far-reaching and illustrate the radical upgrade they can have in any city. Here are the key facts:

If Lisbon replaced all private car, bus and taxi traffic with MaaS fleets of autonomous vehicles, CO2 emissions could be reduced by 62%. The fact that almost one-fourth of the city’s population would choose mobility over their desire to own a vehicle reveals a positive mind-set among most urbanites.

If Helsinki and its Metropolitan Area introduced shared mobility services to replace private cars, buses and taxis, Co2 emissions could be reduced by 28%, whereas congestion would be minimised by 37% and much of public parking space could be used for other purposes.

The reduction of emissions in the Helsinki area is lower than the one in Lisbon because Finland’s capital already has a strong public transport system and, in addition, many citizens go by foot or bike, leaving less room for improvement. As the average trip length in Helsinki is longer than the one in Lisbon, emissions tend to be higher per trip for the same vehicle occupancy.
