**Abstract:** Constraint-based models and models constructing accessibility measures mainly
focus on single agents having only one available transport mode. However,
numerous cases exist where multiple agents or groups of individuals with
different available transport modes want to participate in a joint activity at a
certain location. The aim of this paper is to provide new insights into
representing and reasoning about feasible space–time opportunities for multiple
agents. Relying on concepts of time geography, we propose a conceptual
framework in order to determine interaction spaces for groups of individuals.
Besides availability of means of transport and the locations of each individual,
minimum activity duration and opening hours of opportunities are taken into
account. The reasoning about space and time is visualized in three dimensions
using a hybrid (CAD/GIS) system.

Using time geography as a point of departure, the purpose of this paper is to
model and visualize the interaction possibilities of multiple individuals.

time geography is a framework for understanding human spatial behaviour, providing
a foundation for recognizing paths through space and time and measuring accessibility.
it works with a set of constraints, from individual constraints (eating, sleeping) to
places with different accessibility rules.
different actors that can use different vehicles which may have different speeds.

this work uses agents merely as (x,y) points, and it computes
the possible interaction spaces for pairs of agents.
