Analysis of pedestrians behaviour based on simulated urban environments and its incorporation in risk modelling
Main objectives
The objective of this research is to develop new and improved algorithms for describing pedestrian and vehicle interaction at unsignalized crossings, using a pedestrian simulator and to implement them in a traffic microssimulator environment. The algorithms will address pedestrian behavior at intersection crosswalks, based on field and controlled experiments. The models will describe pedestrian-vehicle crash (function of geometric, individual characteristics and perceived risk, vehicle traffic, pedestrians traffic, type of road pavement) and will also be compatible in form with algorithms used in microsimulation tools.
Task 1: project management and dissemination
The aim of this task is to assure the coordination of the team researchers, the compliance with the outputs of the project, the adequate dissemination of the results and professional financial management.
The management and dissemination of the project concerns with the day-to-day coordination, the monitoring and reporting of the research progress, the communication strategy (including writing papers and workshop organization) and the consolidation of the project’s elements and deliverables (planning, progress reports, milestone reports, financial management).
Task 2: Analysis of pedestrian behavior in real environment – field studies
The main objective of the current task is to analyse pedestrians’ behavior in real environment, at three and four leg intersection crossings with different traffic and pedestrian flows, to parameterize the inputs of tasks 3, 4 and 5 and to validate the final results.
Task 3: Road environment simulation
To design road environments.
Task 4: Analysis of pedestrian behavior in a simulated road environmnet
Use the simulated environment to assess pedestrian behavior and performance during relevant tasks, like lane crossing, collision avoidance or time-to-contact estimations, for different simulated conditions according to the variables on study.
Task 5: Integration of pedestrian behavior risk factors in modelling
This task will be performed to investigate the role of selected influencing factors and to check hypotheses that have been formulated. This task will be directed to the following specific goals:
-
To analyze the existing risk assessment approaches
-
To establish a methodology to determine and rank risk factors
-
To determine risk factors and their interdependency
-
To rank risk factors
-
To model pedestrian-vehicle crash (function of geometric, individual characteristics and perceived risk, vehicle traffic, pedestrians traffic, type of road pavement).
