An autonomous system for maintenance scheduling data-rich complex infrastructure: Fusing the railways’ condition,planning and cost

National railways are typically large and complex systems. Their network infrastructure usually includes extended track sections, bridges, stations and other supporting assets. In recent years, railways have also become a data-rich environment.Railway infrastructure assets have a very long life, but inherently degrade. Interventions are necessary but they can cause lateness, damage and hazards. Every day, thousands of discrete maintenance jobs are scheduled according to time and urgency. Service disruption has a direct economic impact. Planning for maintenance can be complex, expensive and uncertain.Autonomous scheduling of maintenance jobs is essential. The design strategy of a novel integrated system for automatic job scheduling is presented; from concept formulation to the examination of the data to information transitional level interface, and at the decision making level. The underlying architecture configures high-level fusion of technical and business drivers; scheduling optimized intervention plans that factor-in cost impact and added value.A proof of concept demonstrator was developed to validate the system principle and to test algorithm functionality. It employs a dashboard for visualization of the system response and to present key information. Real track incident and inspection datasets were analyzed to raise degradation alarms that initiate the automatic scheduling of maintenance tasks. Optimum scheduling was realized through data analytics and job sequencing heuristic and genetic algorithms, taking into account specific cost & value inputs from comprehensive task cost modelling. Formal face validation was conducted with railway infrastructure specialists and stakeholders. The demonstrator structure was found fit for purpose with logical component relationships, offering further scope for research and commercial exploitation.     

Mechanism Analysis and Implementation Framework for Traffic Signal Control of Over-saturated Intersection Group

For the purpose of improving traffic signal control at over-saturated intersection group, the traffic control targets and structure were optimized, and an implementation framework was proposed. After analyzing the congestion inducements, the maximum throughput and minimum average queue of critical route were selected as the optimization objectives. The critical route layer was added to optimize control structure. The implementation framework for signal timing plan optimization was also put forward considering the over-saturated traffic control characters. Detailed optimization measures for each layer were also discussed. Simulations with the traffic data of an intersection group at Guangzhou Road in Nanjing were selected to compare the performance of dynamic timing plan using proposed strategy and static timing plan. The results indicated the proposed method can be used to optimize traffic signal control of over-saturated intersections group with satisfying robustness and reliability.
