2.2.1 Europe’s eSafety Vision [4]
The European RSAP, developed by the EC, lays out the over-arching European
strategy to road safety, including road design and operations, vehicle design
(crashworthiness), emergency response, and active safety (eSafety). The concept
of active safety is firmly established within the RSAP as an important program
component. For example, some potential government policy and program measures discussed in the RSAP are the following:
• Regulatory measures for active safety systems;
• Development of a plan to implement vehicle-vehicle and vehicle-roadside
communications systems;
• Fiscal incentives for purchasers of active safety systems.
“eSafety,” a key component of the RSAP, is a government-industry initiative for
improving road safety by using information and communications technologies. The
overall objective is to join forces to create a European strategy to accelerate the
research, development, deployment, and use of “intelligent integrated road safety
systems” to achieve the 2010 goal noted above. Systems envisioned are collision warning and mitigation, lane-keeping, vulnerable road user detection, driver
condition monitoring, and improved vision. Other technologies will provide for
automatic emergency calls, adaptive speed limitation, traffic management, and
parking aids.
As an indication of the significance of the eSafety initiative, eSafety strategy is
led by a high-level group consisting of top executives in the automotive industry and
government organizations. Implementation is then the responsibility of an eSafety
working group, which is composed of key professionals in these domains.
eSafety focuses on both stand-alone IV safety systems and cooperative systems
that will enable essential safety information to be exchanged between vehicles and
the infrastructure. This broader access to situational information will allow more
accurate assessment of risk and a more robust response.
Recommendations from the initial eSafety strategy group included the development of an implementation road map that balances business, societal, and user
issues; development of digital maps capable of supporting safety systems; incentives
to stimulate and support road users and fleet owners to buy vehicles with intelligent
safety functions; and increased levels of international cooperation in areas such as
standardization, development of test methodologies, legal issues, and benefits
assessment.
Participants describe the eSafety vision as follows:
“The driver is sitting behind the steering wheel and is driving at 70 km/h. He [or she]
steers the vehicle into a corner. To do so he [or she] uses information acquired by looking at the total road picture, the surroundings and his [or her] in-car instruments. The
in-car applications continuously receive information from cameras (visible light and
infrared), in-vehicle radar systems, digital maps, GNSS satellites for location information, vehicle-infrastructure communication, information from other vehicles and the
like. The information collected by these sensors is verified by the in-vehicle control
unit, integrated, analyzed and processed, and presented to the driver.
12 Goals and Visions for the Future
The driver is aware that his [or her] car is equipped with a sophisticated safety system. Depending on the degree and timing of the danger the system would inform
him [or her], warn him [or her], actively assist him [or her] or ultimately actively
intervene to avoid the danger. If the intervention cannot avoid the crash completely,
intelligent passive safety applications will be deployed in an optimal way to protect
the vehicle occupants and possibly other parties involved in the accident (vulnerable
road users). The system will also automatically contact the emergency services indicating the severity and location of the accident.”
A significant set of R&D projects are now under way in Europe under the
eSafety banner, as described in Chapter 4.
2.2.2 Sweden’s Vision Zero [11]
Sweden has led the way in safety by introducing its Vision Zero concept—a future in
which no one will be killed or seriously injured in road traffic. Vision Zero has
strong backing from the Swedish parliament and forms the foundation for road
traffic safety initiatives in Sweden.
A key principle is to ensure that roads and vehicles are adapted to the limitations of human drivers, including automatic means of limiting vehicle speeds as
appropriate to the situation. While full implementation will take many years, since
the introduction of Vision Zero in 1995 and the beginning of road safety improvements, deaths and serious injuries on Swedish roads have not increased despite an
increase in traffic.
Vision Zero comprises the following eleven priority areas:
• A focus on the most dangerous roads;
• Safer traffic in built-up areas;
• An emphasis on the responsibility of the road user;
• Safer bicycle traffic;
• Quality assurance of transport (shippers and freight carriers);
• Winter tire requirements;
• Better use of new Swedish technology;
• The responsibilities of designers of the road transport system;
• Societal handling of traffic crime;
• The role of voluntary organizations;
• Alternative methods for financing new roads.
From a vehicle perspective, the approach encompasses greater cooperation
between the automotive industry and road designers, as well as safer vehicle design in
terms of crashworthiness and occupant protection. The continued development of IV
safety systems by domestic car manufacturers Saab and Volvo is also supported.
2.2.3 ITS America’s Zero Fatalities Vision [12]
The Intelligent Transportation Society of America (ITS America) was established in
1991 to coordinate the development and deployment of ITS in the United States. A
