Cities must become fully car-free in order to be liveable in the future, according to the UCL experts behind a new modelling report looking at urban car use.
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.

Ramírez) One of the severe challenges with anti-vaccine views is that they might be shared by individuals with high centrality in the social network, as they are more exposed to them..Central nodes play a highly relevant role in the diffusion of anti-vaccination views and the pandemic evolution.
Views in favour or against a vaccine are transmitted - frequently as an intentional act - from one person to another. Typically adjusted to fit distinct narratives, misinformation moves rapidly through social networks. With regard to the vaccine for COVID-19, different anti-vaccine narratives are being created and can have critical consequences when adopted by large population groups. This paper considers a network-based population model and five vaccination strategies varying the proportion of the population that has received the vaccine. Considering that individuals who share anti-vaccination views will refuse a vaccine, the research quantifies the burden anti-vaccination narratives ha
