Linkway

Inspiration Navigating public transit with accessibility needs should never be a gamble. During transit expansion projects, sudden, unannounced changes to walkways, lifts, and step-free paths occur frequently. While able-bodied commuters experience minor inconveniences, wheelchair users, seniors, and parents with strollers face total route failures and complete dead ends. We wanted to build a solution that moves navigation from reactive to proactive.

What it does LinkWay is a real-time, software-defined accessibility navigation app that predicts transit barriers like broken lifts instantly. By combining official public transport data with crowd telemetry, it flags unannounced infrastructure failures and dynamically routes commuters along safe, step-free paths before they hit a dead end.

How we built it

Frontend and UI: Designed using rapid prototyping workflows on Lovable.dev, focusing on a clean mobile experience with dedicated accessibility toggles.
Spatial Logic: Powered by Turf.js to handle lightweight geospatial calculations and mapping directly on the device under a tight bundle size.
Data Integration: Fuses live data feeds from the LTA Datamall API with passive, privacy-first movement vectors to detect pedestrian slowdowns and clusters.

Challenges we ran into Balancing real-time anomaly detection with strict user privacy was our biggest hurdle. We had to ensure that user movement telemetry was processed locally on-device so that personal mobility profiles and locations remained completely anonymized before generating aggregate disruption alerts.

What we learned We gained a deep appreciation for the complexities of civic tech engineering, optimizing geospatial algorithms like spatial clustering for mobile browsers, and designing user-centric interfaces that solve real-world inclusion problems.
