Tactical design of an integrated mobility system

Project Details

Description

An integrated mobility system allows people residing in rural areas, who
typically do not have access to public transport within walking distance,
to reach their destination using a combination of collective on-demand
transport services and public transport. Users submit a single request for
their entire trip at a mobility center. When planning the users’ trips, the
mobility center must ensure that the flexible routes and schedules of the
on-demand vehicles are synchronized to the timetabled public transport
in order to enable smooth changes for the users involved, also respecting
the users’ time preferences and maximum ride times. This gives rise to a
challenging routing and scheduling problem.
Existing literature mainly focuses on this operational aspect, assuming
that a certain public transport network is given. This research proposal
presents a methodology to optimize the tactical network design, since
the initial choice on where to offer regular public transport versus ondemand services has a considerable impact on the operating costs and
service quality of the eventual system. Second, this research proposal
aims at incorporating additional real-life features into existing routing
and scheduling algorithms for the on-demand layer of the system. For
example, the dynamic nature of the problem (e.g., delay management,
requests received during the operations, …) will be considered, which
requires fundamental extensions to the existing static approaches. The
proposed research delivers fundamental contributions to the academic

literature on vehicle routing with synchronization. The resulting solution
technique can be applied by decision makers (such as the government’s
mobility department) to optimize the design of their mobility system. In
addition, the operational layer of the proposed tool can be implemented
by on-demand service providers in support of their real-time activities. It
will improve the cost efficiency and service quality of the integral system.
