The document discusses a cooperative platform for roadside equipment communication with vehicles, aimed at improving efficiency and safety in transportation. It highlights the platform's features such as open communication, continuous driver feedback, and the ability to support multiple applications which address challenges faced by emergency services, logistics, and public transport. Key benefits include reduced emissions, improved travel times, and economic attractiveness for cities, alongside specifications for vehicle and roadside routers.

2. Cooperative systems
Cooperative systems offer a universal way for roadside equipment to
communicate with vehicles. It provides open connectivity, as promoted by
the European Commission. And it also allows multiple applications, to run
side by side.
Challenges to solve
Current priority solutions for emergency vehicles and public transport use
dedicated systems. This requires a substantial investment per service which
is not very efficient when authorities are considering multiple services.
Another disadvantage of these dedicated systems is the lack of information
sharing possibilities. Why can we not use a universal platform for this?
Driver feedback, if used at all, is limited to simple broadcasts and mostly
only at specific locations. Isn’t there a way to subtly inform drivers and
inform continuously with information targeted at certain vehicles only?
The performance of state of the art safety, efficiency and environmental
applications is limited, not only to the algorithm used, but also to their
sensor and information distribution capabilities. Applications can’t share
information easily, and information can be distributed easily to specific
drivers. How can we remove this limitation?
How our platform will help you
Our platform solves all of above challenges. It offers open communication,
continuous driver feedback and it allows multiple applications to run on
the same platform. It consists of vehicle and roadside components. On
the roadside it can be connected to Peek and third party Traffic Light
Controller’s via the Ivera protocol. Application management, configuration
and system monitoring is done via our easy to use and new web based
management tool. This is how authorities and fleet owners access the
system. Drivers interact with the system via an Android touch screen device.
Currently we offer two applications:
1. In-vehicle time to green. Continuous real time driver feedback
for Heavy Goods Vehicles. This reduces emissions and decreases
congestion;
2. Priority services, with in-vehicle confirmation. This improves safety and
provides shorter travel times for emergency vehicles.

3. Open communication technology
Recently the European commission gave way to the exclusive use of 802.11p
bandwidth for ITS applications. This bandwidth can be used for communication
between vehicles, and between vehicles and roadside equipment. Standardised and
secure communication will enable a whole range of innovative applications. We
took the opportunity to develop an end-to-end cooperative platform for the ITS
domain. With this platform priority services for logistics, emergency services and
public transport operators are available. This innovation will remove the remaining
thresholds from the current equipment generation for good.
Future proof
The standardized WiFi technology and the layers on top of that secure communications
interoperability (subject to ETSI standardisation). Both the roadside and the vehicle-
side architecture support multiple applications running side by side. This provides a
future proof solution.
Features
ƒƒ 802.11p communication
ƒƒ Platform architecture allows easy extension with new services
ƒƒ All priority services consolidated into one platform
ƒƒ Conditional priority at traffic intersections
ƒƒ Continuous feedback to the driver (prediction of waiting time)
ƒƒ Web-based management tool
ƒƒ Easy installation (i.e. RSU router only requires 1 cable)
Benefits
From a road-authority’s perspective:
ƒƒ A future proof and innovative platform;
ƒƒ A quicker response time for emergency services;
ƒƒ Improved safety at intersections;
ƒƒ Meeting emission reduction targets as set by governments;
ƒƒ Reduction in fuel consumption;
ƒƒ Priority or prolonging green-time as incentives to foster green routes;
ƒƒ Investing in roadside equipment yields economic attractiveness for the city.
From the emergency services perspective:
ƒƒ Increased safety when crossing intersections;
ƒƒ Shorter travel times to reach an accident;
ƒƒ Less damage through accidents at intersections.
From a logistic service provider perspective:
ƒƒ Reduction of fuel- and maintenance costs;
ƒƒ Shorter transport times, lower costs, improved utilisation;
ƒƒ More reliable planning.
