A new study from our group together with researchers from Universidad de Chile and Technical University of Denmark reveals the impact of real-time public transport apps on urban mobility and the environment. Published in Travel Behaviour and Society, the paper examines Chile’s Red Movilidad app, offering insights for cities worldwide.
🔑 Key Contributions:
1. Behavioral Shifts: 23.5% of bus users changed travel behaviour because of using Red—10.5% changed travel mode, while 13% optimized routes/stops. Buses gained 3 passengers for every 2 lost, showcasing a net demand increase for public transport. This is because the real-time information on bus location and waiting-time makes public transport more attractive to use.
2. Environmental Benefits: The app reduced vehicle kilometers traveled (VKT) and cut CO₂ emissions, because of the modal shift that it induces, mostly from car-based modes (shared taxis and ridesourcing) to buses.
3. Policy Implications: Emission reductions depend on vehicle standards. While CO₂ dropped, local pollutants (NOₓ, PM) only decreased with cleaner fleets (Euro VI/Electric), highlighting the need for fleet modernization.
🌍 Why It Matters:
This study is the first to quantify how real-time public transport apps may reduce traffic and emissions in medium-sized cities. It bridges the gap between digital innovation and sustainable urban planning, proving that accessible information can drive greener choices.
🚌 Takeaway for Cities:
Investing in real-time transport apps isn’t just about convenience—it’s a climate action tool. Pairing tech with clean vehicle policies can accelerate progress toward net-zero goals.
