A public agency is seeking a vendor to develop a branded trip planning app solution for Android, iOS, and web platforms. The selected vendor will be responsible for delivering a robust, scalable application that adheres to detailed functional and non-functional requirements, including integration with multimodal transit data sources for accurate routing, passenger count, occupancy information, and real-time service alerts.

The app must be designed according to strict brand guidelines, covering interface elements such as logos, color palette, typography, and accessibility compliance. The platform should ensure a consistent and intuitive user experience across all screens and notifications, as well as support regional defaults, multiple languages, and customizable accessibility features. The solution should also include event-specific branding capabilities and offer web APIs for extended interoperability.

In addition to development, the vendor will be responsible for creating a comprehensive launch plan, including timelines, budget, risk management, and validation of brand integration in both staging and production environments. Supporting materials such as notification templates, customer contact protocols, quick reference guides, and recorded training sessions must also be provided to facilitate a successful launch and user adoption.
