Project
Understanding and modelling individual walking and cycling behaviour, involving the within and between mode interactions and with infrastructure (Theme I, project T1.1).
This research aims to set up the behavioural theory of pedestrians and cyclists and develop mathematical models for walking and cycling. The models shall focus on the individual (microscopic) level, capturing the split-second decisions regarding motion and the interactions of traffic participants with each other and with the infrastructure. Psychological literature will be the starting point in setting up a comprehensive behavioural theory, while empirical and experimental data collection and analysis will be performed to underpin the theories and calibrate the models.

Project
Retrieving information about crowdedness conditions and events from social-media data for off-line and on-line purposes.
This research involves 1) identification of relevant information from social media data sources, such as Twitter, Instagram, and Foursquare, 2) developing the methodology for analyzing those data, and 3) correlation analysis with other data sources, such as camera and wifi.

Position: PhD candidate

Project
Although Xiaochen does not fulfill a full project position, she is a member of the Allegro team since her research topic is closely related to the Allegro objectives. The research addresses multi-modal route choice behavior, particularly focussing on the interplay between the public transport and the active modes, which explains the connection with the Allegro project. During the research, real data sets will be analysed to create and verify theories.

Project
Development of the SL-UML app (Theme II, L3).
Project L3 deals with developing an interactive and context dependent app for monitoring, surveying, and actuation of cyclists and/or pedestrians. Besides this practical part of the research, algorithms will be developed to support pedestrians and cyclists to reduce the pressure on the urban network focussing on decentralized control mechanisms. These algorithms will address route choice problems as well as activity scheduling problems.

Project
Establishing which factors determine the route and activity choices in an urban environment based on empirical data (Theme I, project T2.2).
This project analyses the factors that play a role for active mode travellers in deciding to choose a particular route through the city or to choose where and when to perform a certain activity in dependency of the trip purpose. To this end, an exploratory, big-data inspired approach to look for correlations between behavioural outcomes and various factors will be used in a first step. In a second step, a model-based analysis using the mathematical models developed in T2.1 will be carried out to reveal more complex determinants of the choice behaviour of slow travellers.

Project
An integrated activity scheduling, mode and route choice approach for active modes in the urban environment (Theme I, project T2.1).
In this project theory and models are developed for activity travel choices. Route choice, mode choice and activity scheduling are the components for integrated model and theory. Before the travel is initiated several choices need to be made. A person needs to determine which activities are performed (e.g. work, visiting friends, grocery shopping), in what order they need to be performed, how much time they will take and so on. Next to that, a person needs to determine how he will get to the activity destination. Will he go cycling or walking or will he for example walk to the train station, take the train and then rent a bike to get to the final destination. Also, a person needs to decide on the route he will travel to get to the activity location. These choices will first be viewed separately before integrating them into one model. The role of knowledge of the environment and the use of ICT services will also be evaluated regarding activity travel.

Project
The aim of this research is to develop macroscopic flow models for pedestrian, bicycle and mixed flow, for large scale applications (Theme I, project T1.2). By taking an aggregate approach, pedestrian and bicycle movements are assumed to be similar to a flow of people. Concepts used in fluid dynamics (such as conservation of mass and momentum) will be used to describe the flow of pedestrians and cyclists. Flow features of this active mode traffic will be identified and analysed. Ultimately, the newly developed macroscopic model will be calibrated against observational data.

Project
Unravelling Urban Cognition – Acquisition, memorisation and utilisation of spatial cognition in urban environments (Theme II, T3).
Research will focus on theory development of conceptual and mathematical models focused on the perception and cognition of pedestrian and cyclists about the way they acquire, memorise and use (spatial) knowledge of the urban environment for wayfinding behaviour. Particularly of interest are 1.) how this cognition evolves over time, 2.) what the impact is of salient landmarks, 3.) what the role of ICT services can be to enhance urban cognition, and 4.) how network complexity influences urban cognition of individuals. Different types of experiments, deviating from low- to high-tech, will be conducted over a timespan of 2 years to gather qualitative and quantitative insights into the cognitive wayfinding behaviour of people in city centres.
