Unmasked! The Mexico City superhero wrestling for pedestrians' rights

The rate of roadway deaths in Sweden is at an international low due to an approach called Vision Zero. Now the country’s approach faces perhaps its stiffest test: the streets of New York City.

A second year of decline demonstrates that a project to reduce traffic fatalities works, said a safety advocate, who called on the mayor to expand the effort, termed Vision Zero, which lowers speed limits and raises enforcement.

Clogged with traffic, crippled by poor infrastructure – the capital is notoriously hard to navigate on foot. Enter Peatónito, the activist fighting for safer streets.

According to new Indian laws, if a Good Samaritan helps a road accident victim they should expect to be treated with respect by hospitals, the courts and the police.

How can traffic efficiency be improved? A Cambridge-based tech firm is pioneering apps that let drivers quickly find available parking spaces (helping save fuel by preventing them from circling the block while they look), alerting local councils when roads are icy, or even increasing the lighting on particular roads when there's an emergency.

Cities tend to be dangerous and difficult places to live for older residents. A private public partnership in New York is catering to seniors through small changes in the city such as para-transit options and seniors-only hours at public establishments.

Sweden's "Vision Zero" program has used a comprehensive approach to infrastructure and regulation to drastically reduce traffic-related deaths, making Swedish roads the safest in the world.

Substitutes for city parking requirements are becoming increasingly popular throughout the United States. Rather than using off-street parking, many housing developers now provide residents with alternatives that promote reduced driving. This method is better for the environment and lowers the cost of housing in urban areas.

In Pennsylvania, many cities face challenges in implementing Complete Street policies to improve street and transportation safety in urban cores. The cities and organizations that have done this successfully offer ideas to others about how they can use creative financing and piloting to overcome barriers and enforce the policy.
