Abstract:
In this talk, we will present some recent work on management of multi-modal road networks with stationary and mobile data. With the increasing penetration of mobile sensors and communication devices, data collected from these mobile devices provide us extra information of road traffic dynamics through a trajectory-based (Lagrangian) frame of reference. This calls for innovations in traditional traffic modelling and optimisation methodologies which mainly operate upon flow-based (Eulerian) measurements. This talk first presents a multi-objective optimisation framework which maximises bus service reliability in congested road networks with use of both stationary and mobile data. On the solution method, we will also present recent work on decentralised algorithms in which local network components are allowed to derive their own control actions based upon local measurements and estimates with communications with their neighbourhood. The work opens new research direction through introducing modelling with mobile traffic data and decentralised optimisation techniques.
