## Products & Services
- **Automated Bus Lane & Bus Stop Enforcement**: The flagship product. A mobile perception system mounted on public transit buses that automatically detects and records vehicles illegally parked in bus lanes or bus stops. This helps cities clear unauthorized parking, improving bus speeds, reliability, and ridership.
- **Automated Bike Lane Enforcement**: A similar system for detecting vehicles illegally parked or driving in bike lanes, enhancing cyclist safety. Currently being deployed in cities like Santa Monica. [cbinsights.com](https://www.cbinsights.com/company/hayden-ai)
- **Digital Twin Modeling & Spatial Analytics**: The platform can also be used to create digital twins of city environments and provide spatial analytics to help governments and businesses solve real-world problems.
- **Civil Traffic Enforcement System**: An integrated hardware and software system (including forward-facing cameras, ALPR, and detection software) that has received UK Vehicle Certification Agency (VCA) approval for use in England to detect parking, bus lane, cycle lane, and moving contraventions.

## Strategic Focus
- **International Expansion**: The VCA approval for the UK market is a major strategic focus, opening a new continent for business development.
- **Product Diversification**: Expanding from bus lane enforcement into bike lane enforcement and general civil traffic enforcement (restricted routes, parking), broadening their addressable market.
- **Continued Innovation**: The company's patent filings and focus on "digital twin modeling" suggest a long-term strategy to become a core data and analytics platform for urban management, not just an enforcement tool.

## Why Work Here
- **High-Impact Mission**: Employees have a clear, tangible impact on making city streets safer and public transit more efficient. The work directly improves quality of life in urban areas.
- **Market Leadership & Reputation**: Joining a six-time GovTech 100 winner and globally recognized leader provides strong career validation and exposure to cutting-edge technology.
