  In most countries population in urban areas is growing, while available
travel infrastructure and resources are limited. At the same time desires to
minimise environmental impact and energy use have led to new requirements in
the field of inner-city transportation. As a result, the portfolio of mobility
services provided is developing in order to improve the use of the available
resources. Computer-based simulation is an accepted means for investigating the
effects of new transportation policies and services. Many researchers are faced
with the question of choosing a suitable simulator for their specific research
question. In this paper, we review a broad spectrum of recent and historically
important applications, in order to provide an overview of available work and
to help researchers make a more informed decision on the selection of a
suitable simulator. We discuss strengths and weaknesses of the applications and
identify gaps for which we argue that more detailed work is required.
