Abstract:Understanding the cost of accessing services in a transit network, and how this varies spatially and temporally is vital for transport agencies to make effective decisions. However, to understand this at the city-scale typically demands the computation of a very large number of shortest path queries, which is computationally infeasible in a practical setting. In this work we define the notion of an access query, an analytical query which returns the aggregate access costs to a set of points of interest within … Show more
