Safety

Increased availability of sensing, communication and computing equipment in modern vehicles presents opportunities for a generational advance in driver assistance and safety functions. However, the growth in the volume and complexity of data also presents challenges for its collection, maintenance and distribution. The SAFESPOT Local Dynamic Map (LDM) contains a structured model of the world. It acts as an interface between sensing modules and the safety applications. It enables applications to extract context-dependent views of the environment and the platform’s state. These unique views differ in spatio-temporal scale, as well as the objects, attributes and relationships they contain. The ability to extract various views from a LDM is seen as an important tool in the development of multiple, advanced applications on a single platform.

The Collision Countermeasure System (CCS) is an ITS traffic control device, consisting of activated warning signs and pavement loop detectors. Its application at a rural unsignalized intersection was intended to enhance driver awareness of cross traffic, thus increasing safety. This three-phase vehicle behavioral field evaluation assessed novelty and longer-term CCS impacts.

Developed Measures of Effectiveness (M.O.E.s) were derived from CCS accident-avoidance operational objectives. Applied M.O.E.s were: (1) drivers’ CCS speed responses in the presence of cross traffic; (2) intersection approach speed reductions; and (3) Projected Times-to-Collision (PTCs), i.e., the elapsed time to which an approaching vehicle would collide with a vehicle in its path in the absence of a timely avoidance response. Human factors (e.g., driver perception-reaction time) accident-avoidance requirements determined critical PTC values that were utilized in the analysis.

The ROSATTE project aims at establishing an efficient and quality ensured data supply chain
from public authorities to commercial map providers with regards to safety related road
content. The ROSATTE project will consider national organisational issues and technical
interoperability issues and include a substantial number of road authorities and motorways
operators, both with and without national road databases. The proposed solution is based on
appropriate procedures and tools to be implemented by road authorities (data owners) at the
different levels (national, regional, local) with respects to their organisational and legal
framework and an adapted harmonised data exchange infrastructure. A viable solution needs
to generate benefits for the administrations them-selves in addition to enabling the data
provision to third parties.

The wintertime traffic accidents in Finland have generated a need to develop context wise weather
information about sudden changes in road weather in order to warn drivers in real-time. There is a
correlation between road conditions and accidents in Finland. E.g. in the year 2003 there was
altogether 254 fatality accidents1 in which 283 fatalities. The road surface was in 24 % of the cases
slippery (60 accidents), in 16% icy (40 accidents), in 4% slushy (9 accidents) in 3 % snowy (7
accidents) and there was water in the grooves in 1 % (3 accidents) (Finnish Road Adminstration
accident report 2003).
The context wise weather information will help the drivers, forwarders and carriers to drive more
safely and to re-route (integrated with dynamic routing services) and schedule transportation in
order to optimise the logistical chain and to improve its safety and the safety of traffic in general.

With rapid advancement of wireless communication technologies, it has become
possible to develop cooperative systems/services where individual drivers, traffic operators
and service providers can communicate with each other.  Road-vehicle communication based
cooperative systems can be used to improve transport performances in many aspects including
safety, efficiency and environment.  This paper explores functionality and technology
feasibilities of cooperative systems/services which are focused on improving road safety.  In
addition, technical issues related to large scale implementation for such systems, as well as
related policy issues are discussed.
