Truck drivers in Baltimore struggle with confusing, contradictory signage for truck routes and lack of clear hazmat detour signage after the Key Bridge collapse.

Workarounds Described

• relies on contradictory physical signage to determine routes
• takes longer alternate routes (around 695) to avoid tunnel restrictions

Implied Software Gaps

• GPS app that resolves conflicting sign information with authoritative data
• Hazmat-specific navigation that automatically plans detours around tunnel restrictions

RouteClear

RouteClear is a GPS navigation app for truck drivers that integrates real-time, verified truck route and hazmat restriction data. It highlights conflicting signage and suggests compliant detours, automatically updating when infrastructure changes like bridge closures occur. Unlike standard truck GPS, RouteClear uses crowdsourced flagging and official city data to resolve contradictions.
