Aging well in the community: Understanding the complexities of older people's dial-a-ride bus journeys
2021
Older peoples' independent living in their own homes and their ability to move around and maintain social relations in their communities have been acknowledged as important aims to support their well-being. In this article, we study Special Transport Services as a means to support older persons with ‘aging in place’ – that is, within their communities. From “go-alongs” (shared dial-a-ride bus journeys) and “sit-down interviews” (at participant's home or a café) with 12 older people living in a Finnish suburb, we explored their everyday dial-a-ride bus trips to the local mall. We used actor-network theory and the concept of motility to show how at first glance what appeared to be simple dial…
A two-phase insertion technique of unexpected customers for a dynamic dial-a-ride problem
2006
Abstract This work deals with a dynamic dial-a-ride problem with time window constraints. In particular, new unplanned requests for service may arise at a vehicle stop and the driver must decide in real-time whether to accept or reject them. For this problem, we have developed a two-phase insertion algorithm based on route perturbations: the first phase, which is run off-line when the vehicle moves between two successive stops, aims at creating a feasible neighborhood of the current route; while the second phase, which is run in real-time every time a new request occurs, inserts, when possible, the delivery stop of the new customer in the current route.
