Functional Design of Road Infrastructure for Intelligent Driving

Abstract:

With the increase in the cost of single vehicle intelligence and the increasing complexity of road environments， the development of smart driving vehicles is increasingly relying on the progress of smart road infrastructure. At present， in different road engineering construction projects both domestically and internationally， unique design ideas and functional modules are proposed for the intelligence of road infrastructure. However， relevant research mainly focuses on a single road function or specific technology， and there is no systematic proposal for the design theory and application system of smart road infrastructure. At the same time， the smart road infrastructure construction requires the development of roadside equipment， pavement materials， and external perception equipment in all directions towards informatization， digitization， and intelligence. Based on a systematic review of typical cases of smart road projects both domestically and internationally， four key technologies for future smart road facilities are proposed in this paper.
