Data synchronization in vehicles for on-board handrail

The road safety and maintenance are very important and costly activities for road operators. Due to the decrease in the cost of the sensors technologies and wireless equipments, connecting maintenance fleet vehicles become very intuitive. It allows to enhance the efficiency and the reactivity of such services. In the present paper we describe an interconnection system that facilitates the data exchange between maintenance vehicles and Network Operation Center (NOC). We detail the data synchronization mechanism used by this system, which is equipping forty vehicles under tests. These tests showed that our system works well and enhance the efficiency of the road's maintenance and incidents' treatment.
