Unmasked! The Mexico City superhero wrestling for pedestrians' rights

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.

There is a misconception that making cities safer for women requires more security cameras. Now, the method of improving public transport systems and lighting up public streets is being implemented and its allowing women to feel safer and enjoy greater mobility.

Copenhagen is a highly livable city, thanks to policies that focus on making streets safe and convenient to walk. The bigger the city, the worse it is to design urban spaces only with cars in mind, says planner and architect Jan Gehl. His top advice is to gather data about people and their movements, making pedestrians as visible in city planning as automobile traffic.

The World Health Organization estimates that $200 billion worth of productivity is lost every year due to untreated poor eyesight. Several organizations, such as EYElliance and Aravind Eye Hospital, are working to combat this problem by administering free vision tests and helping people who need glasses get them at an affordable rate.

Urban planners in Belgium are creating play spaces, known as the “speelweefselplan,” to give children more room to be outside. The design process includes asking schoolchildren about their routes to and from school, and then planners map out ways to make those routes more interactive. As cities grow and traditional parks are limited, this model shows a way that cities can continue to be welcoming for children.

Radar, lidar, and sensors guide the world’s first autonomous tram across Potsdam. While not yet commercially viable, the tram is an advancement in driverless technology. It can respond to road hazards faster than a human and runs on energy from wind and solar.

In London, a new initiative called Junior Roadwatch is engaging children as traffic safety enforcers. Around one particularly busy and dangerous section of road, drivers who are caught speeding have two options: get a ticket or be questioned by a group of school-aged children. While newly developed, the initiative, devised by The Met Police and Transport for London, has stopped over 90 individuals for speeding, all of whom chose to answer questions from children about the consequences of their actions.

A pilot project in several American cities has provided a large amount of data on how residents use streets where vehicular traffic is restricted. The initiative tested out ways to calm traffic, provide space for families to convene and exercise, and provide safer bike lanes. A transportation analysis firm was able to provide detailed analysis for how each city responded to the changes, opening up ways for governments to "implement the best project for that specific need and measure against those goals."

Bellevue’s pilot bike lane project is starting slow and ready for feedback. By beginning the project with less than a mile of bike lanes downtown, the city made sure to brand it as a pilot, hoping to measure results and adapt accordingly. Also, the Bellevue Downtown Association had a clear voice in expectations for any bike lane project, all of which were met in the initial pilot. The city hopes that bringing on board urban planners, city council, and the downtown association will increase chances of long-term success.
