Electrical bus fleet simulator – system level validation

Posted on February 26, 2020 by nradmin
A key method in the optimisation of novel electric vehicle systems are simulations. Simulations provide important information that can be utilised to plan an optimised system with reduced total costs and harmful emissions, or optimise the operation of a system with digital-twin solutions. However,...

Impacts of connected and automated driving on national road authorities’ policy targets

Posted on September 10, 2019 by nradmin
The main purpose of this article is to summarize state of the art on the impacts of connected and automated driving (CAD) on travel demand, travel behavior, traffic flow, safety and energy (reported in MANTRA deliverable D3.1). The review is based on ongoing and recently completed EU and national...

Tests are underway in VTI’s new bicycle simulator

Posted on September 4, 2019 by nradmin
A project is currently underway in which VTI’s recently developed bicycle simulator is being used to study the interaction between cyclists, and drivers. The aim is to investigate how different infrastructure designs and types of vehicles influence cyclist behaviour at intersections. The...

VTI’s simulators are being used for emergency vehicles 

Posted on March 11, 2019 by nradmin
Better accessibility and shorter response times for emergency vehicles – this is something that standardised, directed, traffic messages, transmitted over the 5G network can contribute. Within the EU project Nordic Way 2, a functioning prototype of such a service is being developed. This is being...

EU project on traffic safety and crash testing

Posted on August 27, 2018 by nradmin
A virtual model of the human, developed in the the Vinnova financed project VIVA
Crash safety testing is one of the tools used to improve safety on roads. The EU is therefore funding a research project that started recently to develop virtual methods of crash testing. The long-term goal is to supplement the physical evaluation of crash protection in and from the cars by virtual...

Simulator used to practice emergency responses safely

Posted on December 6, 2017 by nradmin
Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport Research Institute (VTI) offers a unique...

Preparing for automated vehicles

Posted on September 13, 2017 by nradmin
Automation of traffic systems will lead to major changes. The European Union’s (EU) CoEXist research project began in June 2017 with the aim of preparing cities and road operators for the introduction of self-driving vehicles. The Swedish National Road and Transport Research Institute (VTI) is...
