An accessible world is crucial for people of all abilities to work, live, and play. However, even in the most progressive cities, people with disabilities struggle to live their lives, which only gets worse in the suburbs and rural areas.

One result of population growth within cities is something called urban expansion, which is the unrestricted growth of housing, businesses, and roads without any specific planning. Urban expansion influences cities’ social and environmental dynamics, causing a number of disadvantages, including longer commutes, higher transportation costs, pollution, and loss of countryside.

When it comes to climate change, the most offending contributor to the increasing carbon emissions is the transportation industry. From cars to trains to planes, Americans love their independence and ability to travel on a whim. Data shows that vehicle miles have increased to 1.58 trillion during the first half of 2018, and researchers believe that airline travel will double over the next two decades.

City planners and researchers claim that more and more people are moving into cities, which is contributing to something called urban density. This term refers to the number of people within an urban area. It’s a crucial factor for city planning — understanding how the city is functioning based on economics, health, geography, and sustainability.

An accessible city benefits all individuals who live, work, and play in that city. This means that the public spaces must be accessible to all, no matter their level of ability. When urban planners design the infrastructure for a city center, several problems and corresponding solutions must be considered to benefit the city as a whole.

Creating a bike lane city infrastructure requires the coordination of the appropriate government agencies, resources, and construction logistics. It’s a time-intensive ordeal; however, the benefits are many for cities that are suffering from intense air pollution, overcrowding, and congestion. Bike lanes alter the city infrastructure and also improve the health of inhabitants.

Portland State University noted that when five major US cities incorporated protected bike lanes into their city infrastructure, bike ridership increased 170 percent.
