Number of Traffic Deaths in New York Falls for a Second Straight Year

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.

As Beijing grapples with pollution caused in large part by the increase in cars on the roads, a tech-based solution has appeared in the form of forward-thinking bicycles. The Chinese bike-sharing system, spearheaded by several startups, allows commuters to find a bike using GPS, pay for it using an app, and drop it off upon arriving to their destination, wherever that may be. A mix of private investment and government support has allowed this market to thrive.

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.

Bozeman, Montana, a city grappling with how to plan for growth in a smart and strategic way, is looking to learn from Fort Collins, Colorado. The two cities are similar in terms of the features that make them appealing: once low-cost, small college towns with beautiful scenery and lots of space. Now, Fort Collins’ population has soared, and critics say development could have been smarter. Bozeman is learning lessons about planning and inclusivity, hoping not to make the same mistakes.

The focus on sound comes at a time when open kitchens and industrial hard-surface designs entice diners’ eyes, but might strain their ears.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."

To combat the effects of rising temperatures due to climate change, Los Angeles piloted an experiment called “cool pavements,” where they coat streets with a light-colored sealant to reflect heat. Researchers are studying how effective this method is at reducing the urban heat island effect. Using a mobile sensor station, they found mixed results: While the surface temperature of the road was cooler, a person could feel warmer on the reflective roads. Figuring out how to balance different heat-mitigating strategies could be helpful as cities like Phoenix figure out how to implement cooling infrastructure.

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."

A startup in California called Crop Swap LA is converting unused front yards into community gardens that can grow crops like kale, rainbow chard, and tomatoes as a way to feed neighbors. Community members can pay for subscriptions for up to $43 a month to receive a bundle of greens and vegetables from the microfarms and homeowners get a share of the profits. Each garden needs to have the proper maintenance, which can make it difficult to scale, but these gardens can help provide access to food to those who don’t have a grocery store in their area.

As building developers in Kenya design new structures that are more environmentally friendly and sustainable, they can look to the Garden City Mall in Nairobi as a successful example. This mixed-use development with shopping, residential, and office spaces uses solar energy, which helps cut energy costs by over 30 million shillings each year. The mall also was the first in the region to receive an international green building certification.
