    This report discusses Intelligent Transport Systems (ITS). This generic term is used for a broad range of information-, control- and electronic technology that can be integrated in the road infrastructure and the vehicles themselves, saving lives, time and money bymonitoring and managing traffic flows, reducing conges-tion, avoiding accidents, etc. Because this report was written in the scope of the Policy Research Centre Mobility & Public Works, track Traffic Safety, it focuses on ITS systems from the traffic safety point of view. Within the whole range of ITS systems, two categories can be distinguished: autonomous and cooperative systems. Autonomous systems are all forms of ITS which operate by itself, and do not depend on the cooperation with other vehicles or supporting infrastructure. Example applications are blind spot detection using radar, electronic stability control, dynamic traffic management using variable road signs, emergency call, etc. Cooperative systems are ITS systems based on communication and cooperation, both between vehicles as between vehicles and infrastructure. Example applications are alerting vehicles approaching a traffic jam, exchanging data regarding hazardous road conditions, extended electronic brake light, etc. In some cases, autonomous systems can evolve to autonomous cooperative systems. ISA (Intelligent Speed Adaptation) is an example of this: the dynamic aspect as well as communication with infrastructure (eg Traffic lights, Variable Message Sign (VMS)...) can provide additional road safety. This is the clear link between the two parts of this report. The many ITS applications are an indicator of the high expectations from the government, the academic world and the industry regarding the possibilities made possible by both categories of ITS systems. Therefore, the comprehensive discussion of both of them is the core of this report. The first part of the report covering the autonomous systems treats two aspects: 1. Overview of European projects related to mobility and in particular to road safety 2. Overview for guidelines for the evaluation of ITS projects. Out of the wide range of diverse (autonomous) ITS applications a selection is made; this selection is focused on E Safety Forum and PreVENT. Especially the PreVent research project is interesting because ITS-applications have led to a number of concrete demonstration vehicles that showed - in protected and unprotected surroundings- that these ITS-applications are already technically useful or could be developed into useful products. The component “guidelines for the evaluation of ITS projects” outlines that the government has to have specific evaluation tools if the government has the ambition of using ITS-applications for road safety. Two projects -guidelines for the evaluation of ITS projects- are examined; a third evaluation method is only mentioned because this description shows that a specific targeting of the government can be desirable : 1. TRACE describes the guidelines for the evaluation of ITS projects which are useful for the evaluation of specific ITS-applications. 2. FITS contains Finnish guidelines for the evaluation of ITS project; FIS is an adaptation of methods used for evaluation of transport projects. 3. The third evaluation method for the evaluation of ITS projects is developed in an ongoing European research project, eImpact. eImpact is important because, a specific consultation of stake holders shows that the social importance of some techniques is underestimated. These preliminary results show that an appropriate guiding role for the government could be important. In the second part of this document the cooperative systems are discussed in depth. These systems enable a large number of applications with an important social relevance, both on the level of the environment, mobility and traffic safety. Cooperative systems make it possible to warn drivers in time to avoid collisions (e.g. when approaching the tail of a traffic jam, or when a ghost driver is detected). Hazardous road conditions can be automatically communicated to other drivers (e.g. after the detection of black ice or an oil trail by the ESP). Navigation systems can receive detailed real-time up-dates about the current traffic situation and can take this into account when calculating their routes. When a traffic distortion occurs, traffic centers can immediately take action and can actively influence the way that the traffic will be diverted. Drivers can be notified well in advance about approaching emergency vehicles, and can be directed to yield way in a uniform manner. This is just a small selection from the large number of applications that are made possible because of cooperative ITS systems, but it is very obvious that these systems can make a significant positive contribution to traffic safety. In literature it is estimated that the decrease of accidents with injuries of fatalities will be between 20% and 50% . It is not suprising that ITS systems receive a lot of attention for the moment. On an international level, a number of standards are being established regarding this topic. The International Telecommunications Uniont (ITU), Institute for Electrical and Electronics Engineers (IEEE), International Organization for Standardization (ISO), Association of Radio Industries and Business (ARIB) and European committee for standardization (CEN) are currently defining standards that describe different aspects of ITS systems. One of the names that is mostly mentioned in literature is the ISO TC204/WG16 Communications Architecture for Land Mobile environment (CALM) standard. It describes a framework that enables transparent (both for the application and the user) continuous communication through different communication media. Besides the innumerable standardization activities, there is a great number of active research projects. On European level, the most important are the i2010 Intelligent Car Initiative, the eSafety Forum, and the COMeSafety, the CVIS, the SAFESPOT, the COOPERS and the SEVECOM project. The i2010 Intelligent Car Initiative is an European initiative with the goal to halve the number of traffic casualties by 2010. The eSafety Forum is an initiative of the European Commission, industry and other stakeholders and targets the acceleration of development and deployment of safety-related ITS systems. The COMeSafety project supports the eSafety Forum on the field of vehicle-to-vehicle and vehicle-to-infrastructure communication. In the CVIS project, attention is given to both technical and non-technical issues, with the main goal to develop the first free and open reference implementation of the CALM architecture. The SAFEST project investigates which data is important for safety applications, and with which algorithmsthis data can be extracted from vehicles and infrastructure. The COOPERS project mainly targets communication between vehicles and dedicated roadside infrastructure. Finally, the SEVECOM project researches security and privacy issues. Besides the European projects, research is also conducted in the United States of America (CICAS and VII projects) and in Japan (AHSRA, VICS, Smartway, internetITS). Besides standardization bodies and governmental organizations, also the industry has a considerable interest in ITS systems. In the scope of their ITS activities, a number of companies are united in national and international organizations. On an international level, the best known names are the Car 2 Car Communication Consortium, and Ertico. The C2C CC unites the large European car manufacturers, and focuses on the development of an open standard for vehicle-to-vehicle and vehicle-to-infrastructure communications based on the already well established IEEE 802.11 WLAN standard. Ertico is an European multi-sector, public/private partnership with the intended purpose of the development and introduction of ITS systems. On a national level, FlandersDrive and The Telematics Cluster / ITS Belgium are the best known organizations. Despite the worldwide activities regarding (cooperative) ITS systems, there still is no consensus about the wireless technology to be used in such systems. This can be put down to the fact that a large number of suitable technologies exist or are under development. Each technology has its specific advantages and disadvantages, but no single technology is the ideal solution for every ITS application. However, the different candidates can be classified in three distinct categories. The first group contains solutions for Dedicated Short Range Communication (DSRC), such as the WAVE technology. The second group is made up of several cellular communication networks providing coverage over wide areas. Examples are GPRS (data communication using the GSM network), UMTS (faster then GPRS), WiMAX (even faster then UMTS) and MBWA (similar to WiMAX). The third group consists of digital data broadcast technologies such as RDS (via the current FM radio transmissions, slow), DAB and DMB (via current digital radio transmissions, quicker) and DVB-H (via future digital television transmissions for mobiledevices, quickest). The previous makes it clear that ITS systems are a hot topic right now, and they receive a lot of attention from the academic world, the standardization bodies and the industry. Therefore, it seems like that it is just a matter of time before ITS systems will find their way into the daily live. Due to the large number of suitable technologies for the implementation of cooperative ITS systems, it is very hard to define which role the government has to play in these developments, and which are the next steps to take. These issues were addressed in reports produced by the i2010 Intelligent Car Initiative and the CVIS project. Their state of the art overview revealed that until now, no country has successfully deployed a fully operational ITS system yet. Seven EU countries are the furthest and are already in the deployment phase: Sweden, Germany, the Netherlands, the United Kingdom, Finland, Spain and France. These countries are trailed by eight countries which are in the promotion phase: Denmark, Greece, Italy, Austria, Belgium,Norway, the Czech Republic and Poland. Finally, the last ten countries find themselves in the start-up phase: Estonia, Lithuania, Latvia, Slovenia, Slovakia, Hungary, Portugal, Switzerland, Ireland and Luxembourg. These European reports produced by the i2010 Intelligent Car Initiative and the CVIS project have defined a few policy recommendations which are very relevant for the Belgian and Flemish government. The most important recommendations for the Flemish government are: • Support awareness: research revealed that civilians consider ITS applications useful, but they are not really willing to pay for this technology. Therefore, it is important to convince the general public of the usefulness and the importance of ITS systems. • Fill the gaps: Belgium is situated in the promotion phase. This means that it should focus at identifying the missing stakeholders, and coordinating national and regional ITS activities. Here it is important that the research activities are coordinated in a national and international context to allow transfer of knowledge from one study to the next, as well as the results to be comparable. • Develop a vision: in the scope of ITS systems policies have to be defined regarding a large number of issues. For instance there is the question if ITS users should be educated, meaning that the use of ITS systems should be the subject of the drivers license exam. How will the regulations be for the technical inspection of vehicles equipped with ITS technology? Will ITS systems be deployed on a voluntary base, or will they e.g. be obliged in every new car? Will the services be offered by private companies, by the public authorities, or by a combination of them? Which technology will be used to implement ITS systems? These are just a few of the many questions where the government will have to develop a point of view for. • Policy coordination: ITS systems are a policy subject on an international, national and regional level. It is very important that these policy organizations can collaborate in a coordinated manner. • Iterative approach to policy development: developing policies for this complex matter is not a simple task. This asks for an iterative approach, where policy decisions are continuously refined and adjusted

    Part I Introduction and justification of the Monitor Building with NatureThis report describes the Monitor Building with Nature in the IJsselmeer region. When itcomes to implementing the concept of building with nature the main issue is not how it istechnically possible, but whether stakeholders consider it possible and desirable. The monitorgives insight into perceptions of stakeholders and provides possibilities for improvements indecision making and in generating societal support for Building with Nature projects. Theproject that developed this monitor is part of the Building with Nature research andinnovations programme.The monitor has the following goals:Describe the (changes in) perceptions and actions related to ‘building with nature’ inhydraulic engineering projects. Among which:1.Describe the situation of the project at the start of the monitoring, include the history of the project, the broad context, the assignment of the project, and the (formal) involvement of stakeholders.2.Make an inventory of the (developments in) observed threats and opportunities at project level (design, project management, process).3.Make an inventory of the (developments in) observed threats and opportunities for building with nature within the external field of force.4.Make an inventory of perceptions related to improvements and the involvement of the different stakeholders.The focus of the monitor is on perceptions of people who are involved in hydraulicengineering projects. For the development of the monitor, existing monitor approaches areused. The focus of the monitor is gathering of information and has characteristics ofconstructivist monitoring. However, the monitor aims to show the diversity of the availableperceptions and actions. The focus of the monitor is not merely on ‘learning’, although whenthe monitor is used in meetings or workshops, it can contribute to learning about building with nature. The monitor is qualitative of nature, with implicit use of indicators. The monitor is one of the initiatives of monitoring within the Research programme Building with Nature. Oneother initiative is for example the monitoring of the Community of Practice in the IJsselmeerregion.Part II The Monitor – QuestionnaireIn preparing for the use of the monitor, three main questions are to be asked. The firstquestion is: what is the focus in the project? The second question is: who are the respondentsand why? There are no universal criteria, nor are these desirable. And the third question is:how do we use the questionnaire? Are we interested in doing face to face interviews, orinterviews by phone? How the questionnaire is used depends largely on the goal of themonitor and the resources (i.e. time, money, people) availableThe questionnaire consists of four different parts. Part A discusses issues related to buildingwith nature within the project and deals with stakeholders’ perceptions of the concept. Part Bdiscusses factors influencing the feasibility of building with nature. Part C is about placingissues on the agenda and possibilities for improvements. Part D rounds up the questionnaire.For analysing the results of the monitor the following elements compromise the framework ofanalysis:1.Aspects perceived as characteristic for building with nature2.Aspects of building with nature in the project3.Best practices of building with nature according to respondents4.Perceptions of factors and conditions which stimulate or obstruct building with nature.5.Perceptions of the future and future possibilities for realizing building with nature6.Perceptions of action perspectives to realize building with nature on large scale in multiple7.projects in the IJsselmeer region.Part III The Monitor testedTo test the monitor two projects were selected as pilots: the dike strengthening project Edam-Amsterdam and the silt catch pit. Applying the monitor in these projects has lead to animproved version of the monitor and lessons learned on how to apply the monitor. It was notpossible to apply the monitor itself in the dike strengthening project, although the process wasvery useful. We found that interesting projects to apply the monitor also are subject tosensitive issues. Great concern is necessary to deal with these issues. Therefore, sensitiveissues require more preparation time.In the project ‘silt catch pit’ we were able to apply the monitor and make a case description ofthe project. Applying the questionnaire and developing the case description lead toimprovements of the monitor and recommendations on its use.On the development of the monitor, the following is concluded:•Applying the monitor results in a broad insight into the feasibility of the building with nature concept, factors which are of influence and insight into the decision making in building with nature projects.•It is recommended to have an exploratory interview before using the questionnaire. This is necessary to gain enough information relevant for the case description, gain permission to apply the monitor and get in contact with the relevant stakeholders.•Applying the monitor in the silt catch pit showed that it is very suitable to find factors influencing the feasibility of building with nature in projects. Because it was only possible to develop one pilot, we recommend to again reflect critically on the monitor when applied.•Sensitive issues may make a project an (more) interesting one for applying the monitor. However, it may be more difficult to acquire permission for application and it may require more time. During application of the monitor one should be aware of the issues. Demarcation of concepts is important for the sake of comparing results, as the questionnaires are used for different persons and in different moments in time•The questionnaire can be combined with workshops or meetings to stimulate the realization of the building with nature concept.•The case description is based on a monitor that is incomplete and is part of developing the monitor. Therefore the case description should not be used as a complete example and should be considered together with the conclusions and recommendations made
