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.

An ideal bike pathway is seamlessly incorporated into city infrastructure, easily serving cyclists and pedestrians without hampering motor vehicle traffic. Preferably in bright contrast with its surroundings, this bike pathway stands out from the pavement to provide recognizable traffic patterns that keep cyclists and pedestrians safe.  

Urban planners have explored many options for bike pathways in order to determine the best option for commuters. 

Bike delineators are one solution to keeping bicyclists, pedestrians, and vehicle drivers safe. They need to meet certain requirements in order to serve individuals with disabilities and be ADA compliant.

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.
