Finally, transit optimization that keeps pace with reality

Go beyond static routing. Spare Engine’s AI dynamically optimizes every trip and vehicle, leveraging Google's live data to ensure your paratransit and microtransit services deliver unparalleled punctuality and responsiveness.

• Live traffic re-routing with Google

Continuously optimize routes and manifests using live Google traffic data, dynamically rerouting vehicles every minute to avoid disruptions and ensure punctuality.

• Turn-by-turn navigation with Google Maps

Provide drivers with familiar, trusted turn-by-turn directions directly in the Driver App, improving route adherence and reducing training overhead.

• Fleet-wide route optimization with AI

Spare AI automatically reassesses and adjusts routes across your entire fleet in real-time, reducing manual dispatcher effort–especially during peak times or disruptions.

Why it matters

Demand for paratransit is up 3.1% annually, putting pressure on agencies to scale service with limited resources. This surge requires advanced tools to do more with less.

Costs are rising too. Each paratransit trip costs over 3x more than a fixed-route trip—making efficiency more important than ever.

With Spare’s AI-powered Engine, agencies have improved on-time performance by over 95%, even during peak hours.

Reducing just 8 minutes of delay per trip with true live traffic can save nearly $10,000– millions annually.
