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.

The Americans with Disability Act outlines the standards required to make a parking lot ADA compliant, specifically when it comes to restriping the parking spots. Over time, the paint in parking lots fades, and it becomes more and more difficult to determine the parking spots. At this point, businesses are required to restripe their parking lot and to ensure that the parking lot is ADA compliant.

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. 

Tactile paving, now known as detectable warning dome tiles, was first developed by Seiichi Miyake in 1965 to help people with vision impairments navigate public spaces.  Major cities and transportation networks throughout the world use detectable warning dome tiles.
 

When people think of cyclists, they don’t often consider that biking could be for men and women with disabilities. Biking can be one of the best ways for individuals for recreational activities or for commuting.

Pedestrians with disabilities are particularly at risk when it comes to street safety. As the largest minority group in the United States at 20 percent of the population, people with disabilities are still under-served—especially when it comes to pedestrian safety.

Curb ramps are the solid ramp that joins the top of a sidewalk to the adjoining street level. Also known as a curb cut or dropped curb, curb ramps are primarily used by pedestrians throughout urban areas where the main mode of transportation is walking. Curb ramps facilitate easy movement from the sidewalk to the road for individuals who use mobility aids.

Individuals with disabilities often are overlooked in the conversation about climate change, extreme disasters, and emergency solutions. Since disabilities can differ, individuals with disabilities can be hard to serve, but as climate change becomes an increasing problem, societies and government bodies need to consider these individuals as well.
