Car Share Programs are strategically designed to target areas with lower daily vehicle mileage, aiming to significantly reduce the prevalence of privately owned vehicles, especially in urban centers like Boston. Studies have compellingly demonstrated the efficiency of car sharing, revealing that a single shared vehicle can effectively replace up to thirteen privately owned vehicles. This expanded access to shared transportation offers households considerable flexibility, enabling them to:
- Reduce the number of vehicles per household.
- Avoid the necessity of purchasing a second car.
- Completely substitute their personal vehicle with shared options.

One of the key benefits of car share programs is the overall reduction in vehicle miles traveled (VMT) by users compared to private car owners. This decrease in VMT directly contributes to alleviating traffic congestion and freeing up valuable parking spaces within cities. Estimates suggest that each shared vehicle can lead to an annual reduction of approximately 18,000 vehicle miles traveled. Lowering VMT is crucial for environmental sustainability as it directly translates to a significant decrease in greenhouse gas emissions, combating climate change and improving air quality in urban environments.
Transportation choices are often heavily influenced by the perceived reliability of travel options. Even in cities with diverse transportation networks like Boston, residents frequently default to personal vehicles due to concerns about reliability. Integrating car sharing into city-managed spaces plays a vital role in enhancing the visibility and accessibility of car sharing as a dependable transportation alternative. This increased visibility can significantly boost public confidence in utilizing multimodal transportation solutions, combining car sharing with other options like public transit and cycling for seamless journeys.
Many areas suited for car sharing are already characterized by walkability, robust public transit systems, existing private car share services, and bike-sharing programs. The strategic placement of additional car share vehicles on-street in these locations further enhances the visibility and ease of access to car share services. This improvement directly reduces the reliance on private vehicles for trips that can be efficiently served by these readily available alternative modes of transportation.
Transit gaps, defined as areas within a city where high-frequency public transit is located beyond a half-mile walking distance, present unique challenges for mobility. Car share vehicles effectively bridge these gaps, providing enhanced mobility options, particularly for individuals who primarily depend on public transportation. By offering a flexible and accessible transportation solution in these underserved areas, car share programs promote greater equity and convenience in urban mobility.
