ROAD SAFETY

MULTI MODAL

SAFETY SIMULATION

Predictive Approaches for a Safer Urban Environment

Improving road safety is of key importance, especially for vulnerable road users on non-motorized modes of transportation. The EU-funded PHOEBE project hopes to allow urban road users to safely switch transportation modes without fearing for their safety.

The PHOEBE team aims to develop an integrated, dynamic and scalable human-centered predictive safety assessment framework for all urban road users. The idea is to bring together traffic simulation, road safety assessment, human behavior, mode shift and induced demand modelling and new and emerging mobility data. This will result in a framework that can be used as a blueprint for cities that want to establish and apply safety assessments methods in an efficient and cost-effective way. 

Project objectives

  1. Develop a new, replicable methodology for dynamic safety prediction and socioeconomic evaluation
  2. Harmonise safety definitions
  3. Develop enhanced and integrated urban risk assessment models and tools
  4. Embody social components into risk assessments
  5. Exploit big data and telematics through artificial intelligence and machine learning
  6. Apply the proposed methodological framework and enhanced and integrated predictive modelling tools in an experimental multi-use-case

Use cases

There are three different use cases for PHOEBE: West Midlands region (UK), Athens (Greece) and Valencia (Spain).

The West Midlands region aims to reduce road space for cars to improve the give it to non-motorized modes like walking or cycling.

The city of Athens intends to do a widespread implementation of 30km/h speed limits as well as promotion of public transportation, to improve safety and reduce congestion. The safety analysis will be focused on KPIs for vulnerable road users.

The city of Valencia wants to encourage non-motorized mobility and improve the network of cyclable routes without compromising the safety of the vulnerable users.

The role of Aimsun

Aimsun is the key partner in PHOEBE project providing simulation solutions using Aimsun Next modeling software.

Aimsun Next will be used in all three use cases to run simulations on how the different measures to be implemented will impact safety and modal shift. Simulation will allow us to evaluate more scenarios than otherwise would be feasible.

In addition, new features will be integrated into Aimsun Next, these are new models developed by project partners and the iRAP road safety assessment tool to enable dynamic road safety assessment based on the prevailing road condition like traffic or weather.
