7.6 Conclusions
In this chapter, the computational analysis of a space-time prism in the context of
time geography theory has been discussed. The concept of a time-varying network-
based prism has been extended by considering the influence of the congestion index
on estimated travel speed over links, which is the extended TVNBP. This type of
prism can be viewed as an estimated space-time prism of origins and destinations
rather than the strict space-time prism of these in time geography.
From the perspective of activity scheduling, concepts of critical link and activity
opportunity have been proposed for scheduling of joint activity participation.
Spatiotemporal analysis of alternative space-time paths between origin-destination
pairs helps to identify the time-dependent critical links of the joint participants.
