Cities “must become car-free to survive” | UCL News – UCL – University College London
The experts have called for a shift in collective behaviour to reduce the number of private cars in cities. Globally, the number of cars produced is increasing faster than the population; 80m cars were produced in 2019, while the population increased by 78m.
The researchers said future city planning must include a focus on reducing dependence on cars, promoting fewer and shorter trips and encouraging walking and cycling as primary modes of local transport. Public transport should be encouraged for longer journeys, the researchers argued, and cars should only be used for emergencies or special occasions.
For the paper, published in Open Science, researchers created a mathematical model of car use in a city, where residents either used a car on a daily basis or used public transport. Estimated costs were the length of time journeys take because this is the biggest factor when deciding how to travel, with the baseline for the model being driving with no traffic.
