"Early Detection of Dangerous Events on the Road Using Distributed Data Fusion", 2014 IEEE Vehicular Networking Conference (VNC)

Intelligent transport systems are a fast developing area of research with great impact on everyday life. One of the main ideas in this area is to use all possible information, coming from vehicles and the infrastructure, in order to make the system ”smarter” and avoid unwanted situations – collisions, accidents, bottlenecks... Sources of data are sometimes unreliable and may lead vehicles or the whole system to wrong conclusions and adaptations. We are presenting the application of a distributed data fusion algorithm to detect dangerous events on the road. This application is adapted to detect the possibility of encountering icy roads based on readings from wireless temperature sensors. It takes into account data not only directly obtained from sensors but also from the neighborhood of each element in the system. This way, we obtain a more robust solution that is flexible to the unreliabilities of the sources of data. We demonstrate the possibility to deduce proper results from unreliable data. The algorithm is tested in emulation, using data from a real testbed, to show the usefulness and correctness of our approach.

"Map based intersection collision avodiance system", 10th ITS European Congress June 2014, Helsinki Finland

Possible accidents caused by the intersections with no traffic control can be prevented by the use of modules integrated to Intelligent Transportation System. Vehicles moving on linear roads can request a data from the map module for the intersections in close range and on their way. Vehicles can share their dynamic data in real-time with the system as well as with the other vehicles in the system. System gather all other cars’ information and evaluate those information against its own information and warn the driver about a possible risk of a collision. There are some rules and filters added to the system so system doesn’t bother drivers with unnecessary information. Prerequisites for the system to warn the driver are; if vehicles are about to intersect in a predefined time period, and if the vehicles are above the certain speed limit. If vehicles are moving on roads where the intersections are by passed with overpasses and underpasses or there are certain road conditions that force the vehicles to slow down prior to meeting then no warning message is generated. Designed system is proven to be successfully producing warning messages when there is only one intersection between the vehicles and vehicle or vehicles exceed the defined parameters in a hazardous way and there is a risk of a collision.

"SPEED MANAGEMENT AT BENDS USING LDM", 10th ITS European Congress June 2014, Helsinki Finland

The traffic accidents cause many casualties throughout the world and create financial losses. For decreasing the traffic accidents, together with the developing technology, applications of the new techniques gets common each day. Regarding the bend slope and angles which constitute one of the accident factors, with a preliminary study to be realized on map static data, it can be ensured that the vehicles can take the bend`s geometrical data while they are cruising and they can be warned instantly in case the situations constituting warning exist by keeping the bend`s geometrical characteristics on the dynamic layers to be established on the static map layers. In this study, the bend slope and angles were calculated with the processing of the road data taking place on the static map layers and was kept on a dynamic layer. The calculation was made regarding the speed that the vehicles cruising on the road were required to have for entering to the bend in a secure way also with the consideration of the vehicle characteristics and it was ensured that they reached to this data with the help of the Intelligent Transportation Systems during their approach to the bend locations and the drivers were informed.

IEEE 802.11p based vehicular networking operational pilot field measurement

Timo Sukuvaara, Riika Ylitalo and Marcos Katz, "IEEE 802.11p based vehicular networking operational pilot field measurement", IEEE Journal on Selected Areas in Communications , Vol. 31, No. 9, September  2013, pp 409-418.

For vehicular networking purposes the main communication standard approach on global scale is the IEEE 802.11p. This protocol-based system, together with the 3G cellular network, was the main elements of our car communications test-bed network. The developed test-bed implements an intelligent heterogeneous traffic safety network between cars and infrastructure. It also offers the possibility to exploit vehicle based sensor and observation data in order to generate intelligent real-time services and a service platform for vehicles. The main goal was to improve traffic safety with accident and weather condition related accurate services, but also to offer a platform for true bi-directional Internet-like networking experience tailored cost-effectively to vehicular environments. This paper presents the field test results of a new standard system for car communication, IEEE 802.11p vehicular networking measurements in Northern Finland (with supporting simulations). The results achieved in developed heterogeneous networking system (with special services) pilot testing are presented also. Based on the experience gained from both field measurements and pilot deployment, we propose a system deployment strategy for simple scenarios with general system efficiency estimation. It is shown that the solution has clear potential for a comprehensive heterogeneous vehicular communication and safety network.
