RideShare

RideShare is an event-focused carpooling platform built for Toleranca marketing d.o.o., Slovenia's leading professional event organizer. It connects conference and event attendees for shared rides, reducing travel costs and carbon emissions while building community before the event even starts.

Drivers post available seats on their route, passengers browse and reserve spots, and organizers get a real-time view of the environmental impact their event is generating — all through a server-rendered interface that works instantly on any device.

Large conferences and business events draw hundreds of attendees from across Slovenia and neighboring countries, most driving alone. This creates parking pressure, increases costs for attendees, and runs counter to the sustainability goals that modern event organizers are expected to uphold. Existing ride-sharing platforms are generic — they don't understand events, don't track environmental impact, and don't give organizers any visibility into attendee travel patterns.

Toleranca needed a purpose-built solution that ties carpooling directly to their events, provides measurable CO2 reduction data, and is simple enough that conference attendees will actually use it without a tutorial.

A server-rendered carpooling platform where every ride is tied to a specific event. The two-step ride creation flow — pick your event, then fill in the route — ensures rides are organized and discoverable. Passengers browse available rides filtered by event, request a seat, and drivers confirm with one click.

The CO2 impact engine calculates emissions saved per shared ride using configurable emission factors, then aggregates the data per event. Organizers see confirmed rides, total passengers, kilograms of CO2 avoided, and reduction percentages — numbers they can put directly into sustainability reports.

The entire UI is server-rendered with fluent-html and HTMX. No client-side framework, no bundle — just HTML fragments swapped via morphing. The result is an interface that feels like a SPA but works on conference Wi-Fi where SPAs choke.

• Event-linked rides — Every ride is tied to a specific event, making discovery and organization intuitive for attendees
• Two-step ride creation — Select event first, then fill route details with auto-calculated distances
• Seat reservations — Passengers request seats, drivers approve or decline, with status tracking throughout
• CO2 impact dashboard — Real-time calculation of emissions saved per ride and per event, with configurable emission factors
• Public impact page — Transparent CO2 methodology and per-event breakdown, shareable by organizers
• Admin panel — Full event, user, ride, and reservation management with impact analytics
• Driver management — Passenger lists, bulk confirm/decline, ride editing, and contact info
• Auth system — Registration, email verification, password reset, and profile management

• Zero-JS architecture — Full interactivity via HTMX morphing swaps, no client-side framework shipped
