Carpool

Carpooling involves two or more people sharing a private vehicle for a common trip, with participants often splitting fuel and other travel costs. The arrangement aims to reduce traffic congestion, lower per-person emissions, and improve overall transportation efficiency.

Carpools range from informal arrangements among coworkers or neighbors to formal programs organized by employers, municipalities, or ride-sharing platforms. They commonly cover commuting to work, school runs, and social or shopping trips. In many regions, high-occupancy vehicle lanes encourage carpool participation.

Coordination is typically through schedule agreements, messaging, or dedicated apps that match riders and drivers by origin, destination, and time. Some platforms support dynamic pooling and route optimization, while traditional carpools rely on pre-existing relationships or predictable routines.

Benefits include reduced fuel costs, fewer vehicles on the road, and lower emissions. Additional advantages can include less parking demand and potential time savings in certain traffic conditions. Challenges include reliability, schedule alignment, safety concerns, and varying insurance or tax treatment.

Policies and history: interest in carpooling rose during energy crises and urban congestion pressures. Programs often provide parking or tax incentives and access to carpool lanes. The growth of digital platforms has expanded options beyond social networks and improved matching.
