Internal workshops boosted knowledge of PHOEBE tools

The PHOEBE consortium is a diverse group of actors with experts from different backgrounds. Thus, not everybody has an extensive knowledge about transport modelling and its related tools – a cornerstone of the PHOEBE project. As the main providers of the these tools, Aimsun and iRAP provided workshops in April to get everyone on a same level of understanding. The forum provided great opportunities to ask questions and engage with the technical experts. This took place over two separate internal online workshops in April, which led to the decision to give other PHOEBE partners the chance to present their plans throughout the project.

Aimsun session on the ‘Aimsun Next’ tool

The Aimsun session highlighted the products of the Spanish software provider, which includes the ‘Aimsun Next’ to evaluate the safety improvements of the different actions taken at the PHOEBE use cases sites: Athens, and Valencia and West Midlands.

The main focus of the session was to familiarise the partners with the limits and opportunities of the microscopic simulation environment. Furthermore, the expected development costs for the PHOEBE framework were highlighted. Just to give an example, it was explained how would be possible to modify the default car following model, what would be the expected effort to do so. This included the integration effort, the re-calibration of the model and the expected simulation running time increase.

This is to kick start the PHOEBE activities coming later in the year, which among others will include the integration of new models related to traffic safety, like behavioral model, safety forecasting methods or demand shift towards safer modes into Aimsun Next, coming from many different partners.

iRAP session on protocols

The session provided an introduction to the International Road Assessment Programme’s (iRAP) protocols and how they work. It provided the PHOEBE technical partners with a good understand of the building blocks of the iRAP Star Rating, Fatality Estimation and Safer Roads Investment Plan protocols.

Starting with an overview of the process and how it is applied across road networks, before zooming into the detail of how the crash types are constructed for each of the road user groups and the basis of their associated risk factors. This was then followed by demonstrating how the crash types build up to provide a measure of the risk across a road network.

The session helped to explore the mechanisms by which the iRAP protocols can interface and be combined with the other approaches that will be used within the PHOEBE project. The workshop was concluded with the provision of a practical demonstration of ViDA – the iRAP’s free-to-air online platform for processing and analysing – to offer real world examples of how iRAP protocols are used.

Overall, the project coordinator and POLIS Network as the dissemination partner agreed that such internal communication was fruitful and can be as important as external dissemination.

Join our session at ITS Europe Congress

We are delighted to announce that our session application was selected by ERTICO, which gives PHOEBE, SOTERIA and V4SAFETY the opportunity to present their plans on the big stage in Lisbon, Portugal. The session SIS 54 ‘a holistic approach to road safety: tools, frameworks and digital solutions’, which will be moderated by POLIS Network, will take place on 24 May 2023 from 14-15:00 in room 5B at Lisbon Congress Centre.

What can you expect?

New technologies, such as ITS, autonomous vehicles or traffic modelling, create new challenges for mixed traffic scenarios in urban environments. In order to road casualties towards the overall goal of achieving ‘Vision Zero’, cities need to consider which novel solutions are worth to investigate. Thus, the three ‘sister projects’ from the same call aim to share their respective angle on enhancing road safety for vulnerable road users, as well as drivers and users of emerging mobility solutions. Furthermore, the gathering of stakeholders from the entire ITS community will be an excellent opportunity to enhance the outreach of all three projects.

All organisers, panelists and project partners are looking forward seeing you in the Portuguese capital. We will inform you about further details via social media (Twitter & LinkedIn) once available.
