Dynamic Crowding Maps for Public Transport
Public transportation is meant to save time, money, and reduce urban congestion, yet one persistent problem remains: overcrowding. Many commuters waste valuable minutes watching multiple packed buses or trains pass by, while others squeeze into uncomfortably full vehicles simply because they lack information about better options nearby.
Existing tools like Google Maps and transit apps provide accurate arrival times, but they rarely display real-time crowd density. Riders are left guessing whether the next bus will have space. This gap highlights the need for smarter, commuter-focused solutions.
The proposed idea is a crowdsourced crowd-level tracker that allows riders to anonymously report occupancy levels with just one tap on their smartphones. To reduce reliance on manual input, the system could also use sensors already present in devices: accelerometers (detecting passenger movement patterns) and Bluetooth signal strength (estimating the number of devices in a confined space). The aggregated data would then generate live “heat maps” of transit lines, showing commuters which upcoming options are less crowded.
The benefits are threefold:
Commuters save time and travel more comfortably.
Transit authorities gain valuable insights for service optimization.
Cities reduce congestion and improve overall transit satisfaction.
This problem matters because inefficiency in public transport discourages its use, pushing people back to private vehicles and worsening traffic and pollution. By making commuting smarter and more predictable, dynamic crowding maps can transform the daily experience of millions while supporting more sustainable urban mobility.
