100 Years After New York's Deadliest Subway Crash

Austria rolled out the KlimaTicket, an annual pass that gives the holder access to all forms of public transportation in the country, to encourage increased use of public transport with an eye toward climate change mitigation. The uptake has exceeded expectations with 134,000 tickets sold within just the first two months, but it's still unclear what effect the program will have on the country's carbon emissions.

Raton, a town once surrounded by eight coal mines, now has a main street of boarded-up buildings. There is reason for optimism as the town diversifies its local economy, betting on "a mix of small manufacturing businesses, health care and specialty services, and hospitality for travelers" to endure the sudden decline in mining revenue. Its calculated revitalization may hold lessons for other towns.

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.

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.

To help essential workers navigate the notorious traffic of Bogota, the city built over 50 miles of an emergency bike network. The plan was in place before the arrival of coronavirus but the execution was sped up to meet the demands of increased bike usage. Other measures were also put into place to make the roads more bike and pedestrian-friendly: Reduced speed limits for cars, a 20 percent increase in private parking for bikes, and a bike registration system to deincentivize bike theft. Efforts to expand bike lanes not only eased traffic, they also helped relieve pressure on the overcrowded bus system.

When news of COVID-19 arrived in the West African Village of Dirty Box Junction, community members and local government were ready to act due to lessons learned from mistakes made during the Ebola outbreak of years earlier. The village along with the rest of sub-Saharan Africa immediately enacted measures – state of emergencies, mandatory screenings, and contact tracing, to name a few – that have kept their case count low, while the U.S. continues to see cases and deaths increase.

In an effort to help get accurate information to the communities who are being disproportionately impacted by the coronavirus pandemic, a program called Live Chair Health has started to train barbers "on chronic issues that disproportionately affect Black communities" and teach them "how to have conversations with their clients about the diseases." Aside from providing COVID-19 information, the initiative has helped patrons access primary care and address other medical issues such as high blood pressure.

To mark the 100th anniversary of the Tulsa Race Massacre, in which a white mob killed hundreds of Black residents and destroyed the thriving neighborhood of Greenwood, the Centennial Commission supported a number of initiatives to learn from the past and build a better future. At the base of an ancient elm tree that witnessed the massacre, Up With Trees distributed 100 elm seedlings to children to plant around Tulsa. The commission convinced state education officials to develop a new curriculum on the massacre for K-12 students.

The forensics-based human rights movement uses forensic science to identify victims of genocide and political violence buried in mass graves, allowing their families to arrange proper burial and bolstering collective history around these events. The strategy has been particularly effective in countries with state-imposed silence around past atrocities, such as Spain, where more than 9,000 bodies have been exhumed since 2000.

The Kansas City Streetcar provides fare-free transportation for residents, which helps to get them downtown and promote more economic development. The fare-free streetcar also makes transit more equitable by removing barriers for low-income passengers and improving mobility for people with disabilities.
