EvacSim is a multi-agent building evacuation simulation featuring pedestrian occupant agents occupying twodimensional continuous free-space to simulate pedestrian egress for building evaluation and evacuation planning support. We detail pedestrian model elements that govern microscopic agent movement such as personal space preservation, obstacle avoidance and moving together as a crowd. We vali...

In order to move away from more formal route-choice models and to avoid calibration issues, visually guided agent-based models have recently been introduced to microscopic urban models of pedestrian behavior. Although the new models produce good correlation between the agents and observed pedestrian movement, there are two problems with them. Firstly, the implementations have lacked an origin-d...

In this paper we report on recent developments in ARTHUR: an approach to support complex design and planning decisions for architects together with the simulation of pedestrian movement and the integration of existing CAD tools on the design table. Following a brief introduction, past and current work that has taken a similar approach will be reviewed. Next we describe a scenario that integrate...

Pedestrian-vehicle conflicts are considered as one of the most common safety problems at signalized intersections. The threat to pedestrian safety is mainly related to the interaction with turning vehicles, especially left-turners (left-hand traffic). This paper aims at analyzing the lag/gap acceptance behavior of left-turning vehicles considering pedestrian movement at signalized crosswalks. F...

Microscopic pedestrian simulation models can be used to investigate pedestrian movement at the urban block and building model scale. In order to develop, calibrate and validate such microscopic models, highly accurate and detailed data on pedestrian movement and interaction behavior (e.g. collision avoidance) is required. We present a data collection approach for studying pedestrian behavior wh...

Spatial layout design must consider not only ease of movement for pedestrians under normal conditions, but also their safety in panic situations, such as an emergency evacuation in a theatre, stadium or hospital. Using pedestrian simulation statistics, the movement of crowds can be used to study the consequences of different spatial layouts. Previous works either create an optimal spatial arran...

Fast development of tracking devices has made trajectory outlier detection (TOD) possible and meaningful. Given a set of trajectories T , a TOD algorithm outputs a subset of T , of which trajectories are different from most of the other trajectories in some aspect(s). These trajectories, namely outliers, can indicate important or interesting information and are thus worth noticing. TOD techniqu...

Pedestrian mobility models can be used for numerous applications such as infrastructure design, evacuation planning, architecture, robot-human interaction, pervasive computing or navigation and localization. Within the scope of this paper, the purpose of such models is to realistically represent the stochastic nature of three dimensional pedestrian’s movement. Our own application focus is to ge...
