Funded projects

C-ITS

Testplattform för framtidens transportsystem (CHRONOS steg1).

• Funding agency: Vinnova
• Project duration: September 2016 to March 2018

Purpose and goal

Swedish industry / academy has high ambitions for fewer traffic fatalities. Intensive development of automated and communicating vehicles is the solution. Testing and validation must be done in a safe and repeatable manner. CHRONOS launches the work of iterative development of a test platform on AstaZero to address the challenges above and enable the full-range research, verification and validation of functions by engineering complex traffic and communication scenarios that are potentially dangerous.

Expected results and effects

The aimed results of CHRONOS’ Step 1 include closer co-operation within the Swedish vehicle cluster and with new telecom operators, continued leadership in active safety, new knowledge and safer vehicles. The planned results of the project are:

• Dimensioning test scenarios for automated vehicle testing
• Initial compilation of future test scenarios that include C-ITS (V2X communication).
• First delivery development of a test platform for future transport systems

Planned approach and implementation

The project consists of eight work packages that are coordinated under work package 1. The respective work packages then implement their work under their own leadership in this overall coordination. Work packages consist of project management / architecture, future test scenarios, scenario development for light vehicles, heavy duty scenario development, development test platform server, development test platform communication, development test platform objects as well as integration and testing.

iTRANSIT

intelligent TRAffic maNagement System based on ITS.

• Funding agency: Vinnova
• Project duration: August 2015 to December 2017

Purpose and goal

The project goals have been to analyze an intelligent transport system and traffic management based on some defined perspectives. The main goals are specified as: - Cost-effective and accurate positioning - An open source of an Facility Layer for an ITS station - LDM / GDM. - Convert a laser-scanned map of the AstaZero test path to other map formats. - An information-aggregated central GDM that can handle and monitor real-time traffic situations and (av) control vehicles to avoid accidents. The goals have been achieved by practically demonstrating all parts publicly on AstaZero.

Expected results and effects

The iTRANSIT project has structured ways of analyzing different perspectives for an intelligent transport system and working closely with industry. This has resulted in VCC benefiting from the project in its DriveMe project. iTRANSIT has supported other projects for commercial components for positioning at very cheap cost. Carmenta AB has supported the project with its products that have been developed further and are now working on developing a commercial product for a multi-modal C-ITS - TrafficWatch (TM). ÅF has used the results in new projects.

Planned approach and implementation

The project has been organized in 5 work packages where SP, VCC & AZ have been work package leaders and pushed the work. Work packages have worked well and results have been shared between all work packages. Results have since been practically demonstrated in work package 5 on the test bed AstaZero. Project research and results have been published for both conferences, but also in scientific publications with peer review procedures.

KARYON

Kernel-Based ARchitecture for safetY-critical cONtrol.

The key objective of KARYON is to provide system solutions for predictable and safe coordination of smart vehicles that autonomously cooperate and interact in an open and inherently uncertain environment.

It is a challenging objective since the same increasingly complex control components and wireless communication, which would allow improving performance, end up introducing new safety risks, which have to be mitigated or neutralized. Addressing this challenge requires innovative solutions in two major problem areas. The first one is to achieve a high availability of the complex control system investigating new ways of achieving fault-tolerant distributed control that allow maintaining a high performance level in the presence of uncertainties and failures. The second is the provision of a safety kernel to constraining system operation in order to avoid hazardous situations.

Chameleon-MAC

Adaptive and Stabilizing Algorithms for Media Access Control in Mobile Ad hoc Networks

• Funding agency: Vetenskapsrådet (Swedish Research Council)
• Project duration: August 2012 to December 2016

Mobile ad hoc networks (MANETs) are autonomous and self-organizing systems where mobile computing devices require networking applications when a fixed network infrastructure is not available or not preferred to be used. In these cases, mobile computing devices could set up a possibly short-lived network for the communication needs of the moment, in other words, an ad hoc network. MANETs are among the fundamental enabling technologies for autonomous mobile systems, such as cooperative vehicular systems and driverless cars, which are important for approaching green transportation objectives and the goal of zero fatality. MANETs are based on wireless communications that require implementation of a Medium Access Control (MAC) layer. MAC protocols need to be autonomous, robust, and have high bandwidth utilization, high predictability degree, and low communication delay. Existing implementations cannot guarantee satisfying these requirements. The Chameleon-MAC project proposes to design and implement self-stabilizing MAC algorithms that guarantee satisfying these requirements by automatically adapt to a variable environment. The Chameleon-MAC project´s holistic approach is unique to this research area; it considers both theoretical and practical aspects of MAC algorithms for MANETs. The Chameleon-MAC project dissemination plan includes scientific publications and prototyping.

Mobile Ad Hoc Networks

Robust Software Infrastructure for Mobile Ad Hoc Networks

• Funding agency: Vetenskapsrådet (Swedish Research Council)
• Project duration: August 2006 to December 2010

Nowadays leading communication technologies elucidate the countless benefits of mobile ad hoc networks (MANET). We prepare theoretical groundwork needed for MANET applications, because of their great social, economical, and industrial benefits. MANET devices have to set up themselves a possibly short-lived network for the needs of the moment. The system is designed to execute forever and is very unlikely never to experience transient failures. Self-stabilizing distributed systems can recover after the occurrence of transient faults. Wait-free operation is guaranteed to complete within a bounded number of steps, even in the face of failures and delays. Our goal is to design a self-stabilizing and wait-free software infrastructure needed for MANET. We present a new modeling of MANET programs that cope well with the unpredictable nature of MANET. The idea is to describe computing entities that make autonomous on-line decisions concerning complex QoS requirements. Later on, concretization of these abstract entities will provide a wide range of applications. An example application domain is vehicular networks that assist in traffic control and improve safety. Using vehicular networks, drivers can be made aware of road hazards and reckless driving. These applications can be achieved by installing mobile computers on automobile vehicles that use wireless communication. This line of research is highly relevant for automakers that are developing vehicular networks.
