Alert Grid

Audible Warning for Shared Cycle Routes

The Alert Grid is an innovative safety solution designed for shared-use paths, cycleways and pedestrian areas where cyclists and pedestrians interact. Installed flush with the surface of the path, the grid produces a distinctive audible warning when cyclists ride over it, helping to alert nearby pedestrians to their approach.

This simple but highly effective system is particularly beneficial in locations where visibility may be limited, such as near bus stops, crossings, access points, and other busy pedestrian areas. By providing an audible cue, the Alert Grid helps reduce the risk of collisions and improves safety for all path users.

Designed with Vulnerable Pedestrians in Mind

For blind and partially sighted people, cyclists can often approach silently, creating a significant safety concern on shared-use routes. The Alert Grid provides an early warning that a cyclist is nearby, giving pedestrians greater confidence and awareness when using the path.

The system is especially effective in areas where visually impaired users may be boarding or alighting from public transport, crossing cycle routes, or navigating busy public spaces.

Key Benefits

• Produces a clear audible warning when cyclists pass over it
• Improves safety on shared pedestrian and cycle routes
• Particularly effective near bus stops, crossings and access points
• Assists blind and partially sighted pedestrians
• Passive system requiring no power supply or electronic components
• Durable steel construction for a long service life
• Suitable for new-build schemes and retrofit installations
• Low maintenance and highly reliable operation

Typical Applications

• Bus stop bypasses
• Shared-use cycle and pedestrian paths
• Public realm improvement schemes
• Parks and recreational routes
• Access points to cycleways
• Transport interchanges
• Urban and rural greenways

A Simple Solution to a Growing Problem

As cycling continues to increase in popularity, ensuring the safety of all users on shared routes has become increasingly important. The Alert Grid offers a practical, robust and cost-effective method of warning pedestrians of approaching cyclists, helping to create safer and more inclusive environments for everyone.
