The Connected and Adaptive Maintenance for Safer Urban and Secondary Roads project (‘CAMBER’) aims to develop and demonstrate improved safety monitoring across urban and secondary rural road networks through real-time data feedback into road maintenance systems and proven low-cost interventions. Performance metrics based on new-generation data sources will provide road managers up-to-date information on safety issues, damage, and routine maintenance and upgrade needs. Data collated from a range of sources, such as telematics, vehicle and smartphone sensors, and road user feedback, will feed into safety assessment models to flag what measures are required to ensure a safe road environment for all road users, including road-user minority groups with varying design needs, such as powered two-wheelers (PTW). CAMBER will support this through much-need research and testing of low-cost road safety interventions and low-impact maintenance techniques, including those for vehicles with advanced driver-assistance systems (ADAS). The approaches will be demonstrated on urban and road networks in five European countries. CAMBER’s economically-sound solutions and new knowledge will be communicated through established networks to European road managers, policymakers and industry to support the decision-making and investment needed for more efficient maintenance for safer urban and secondary roads.
