They may. However, there is more to it than that. Many studies showing reduced health outcomes near highways, including higher impacts on older people. This is a summary from the American Lung Association, so respiratory centered. There are also studies showing higher blood pressure, cardiovascular disease, cancer & others.
"Living near a busy roadway exposes residents to a complex mixture of harmful pollutants that includes nitrogen oxides, particle pollution and VOCs coming from the tailpipes of cars, trucks and buses as well as from the wear of brakes and tires, the resuspension of roadside dust and the abrasion of the road surface itself. Although traffic pollution has an impact on air quality over a large area, people who live closest to highways and other busy roads are most likely to be affected. Long-term exposure to traffic-related air pollution is associated with asthma onset in children and adults, lower respiratory infection in children, and premature death."
