Which housing type has the highest average vehicle trips per unit?

• A. Apartments
• B. Mobile Homes
• C. Condominiums
• D. Retirement Homes

Answer: (A)

Understanding how housing type influences vehicle trips per unit. Trip generation varies with housing type because household size, ownership of vehicles, and travel needs differ, as do the on-site amenities and access to alternatives like transit. Apartments typically show the highest average vehicle trips per unit because they group many households into dense developments, which can lead to a greater mix of trips for work, shopping, and social activities, even when other factors like location suggest some transit access. Retirement homes, by contrast, often center around on-site services and scheduled activities, which lowers the need for driving per unit. Condominiums and mobile homes usually have patterns that result in fewer per-unit trips than apartments, due to differences in occupancy patterns and lifestyle. Therefore, apartments stand out as having the highest average vehicle trips per unit.
