Modelling of System for Transport and Traffic Information Management in Republic of Croatia

The traffic system is expected to provide faster, safer, more reliable, more comfortable and less expensive movement with enabling of maximal personal mobility. One of the necessary preconditions to realize these expectations is the real-time information of all those participating in the traffic processes with all the relevant data. Consequently, it is necessary to design and construct a traffic system that will, with the application of advanced information communication technologies (ICT), insure the backbone that will integrate the users’ services based on the principles of intelligent transport systems (ITS), in order to be able to provide the system users with reliable, precise and timely information necessary for a more efficient realization of the transport process. With the application of modern ICT, the system for traffic information management collects, performs the adaptation process, fusion and processing (verification and addition of weights to each collected information) and carries out the distribution to all the interested users. Thus, new services may be offered that directly contribute to the improvement of traffic system quality by improving the change of space – time (s, t) coordinates of the transported entity which is transported or transferred in adequate transport entity and moves with it along the transport network, with better efficiency of the consumed energy and less polluted environment. The application of terminal user equipment and the developed program package adapted to single users and terminal equipment, allows input of information on the events by the information source or their request for certain information. The system implies the implementation of services of advanced fix and mobile communication systems, and naturally the Internet. By implementing separate modules it will be possible to process different input information received by WEB provider, WAP protocol, E-mail and SMS/MMS messages and the so-called CALL centre. With the previously mentioned communication technologies, RDS-TMC technology for user information by means of radio receiver can be applied in the distribution of data. The information service providers can use output data from the system for traffic data management and thus expand their activity or be exclusive suppliers of traffic information with or without added value. Based on this, with intermodal pre-travel and on-travel informing of the traffic system users, significant improvements can be achieved in dynamic vehicle fleet routing, forecasting of travel time, etc. Modern mobile communication systems offer services which allow realization of real-time informing of all the traffic system users, with the possibility of realizing financial profit of the system for traffic and transport information management (STTIM). Different business models of operation STTIM operation will attract a large number of those interested in performing this, until now in the Republic of Croatia (RH) unrecognized activity.

The Framework of e-Forensics in the Republic of Croatia

With the development of information communication systems and the services they provide, the complexity of the organization of information within information systems is growing. The complexity itself contributes to the increase in the number of electronic incidents and affects the high demands of forensic procedure implementation. It is estimated that in the near future the number of electronic incidents will outgrow the number of classical criminal incidents both financially and quantitatively. Due to the things mentioned above, early identification, discovering and taking legal proceedings against the perpetrator of an electronic incident are necessary. It is necessary to investigate all electronic incidents adequately and promptly and adapt the legal framework and laws related to e-Forensics. e-Forensics is a relatively new discipline within which there is a low level of standardization and consistency. With the purpose of increasing the quality of performing e-Forensics and presenting the evidence in a possible judicial proceeding one has to define the legal framework of e-Forensics. The analysis of current legal standards and methods used to perform e-Forensics is presented in the paper as well as the proposal of performing e-Forensics with defined procedures and methods.

Model of the New LMS Generation with User-Created Content

The Learning Management System (LMS) of the Faculty of Transport and Traffic Sciences has been in operation since 2004 when it was developed for the studying purposes according to the German Fachhochschule study concept and according to the then specific characteristics of studying in the Republic of Croatia. The system consists of five own developed modules (DMS, SAN, e-Student, SMSCentar and FPZmobile) which in synergy form the Faculty LMS. The Document Management System (DMS) is a system of managing documents and processes used for authorized access of the Faculty staff members to the modules that control the work of computer laboratories, e-Learning system administration (publishing of teaching materials, control and assessment of seminar papers, etc.), as well as the module for managing documents and processes within the Faculty (orders for equipment, reports on malfunctions, updated on- line directory, etc.). The authorization and supervision system (SAN) is a set of technologies and applications that allow supervision of students’ work on computers in computer classrooms of the Faculty, and personalization of the working environment in the Windows operating system, regardless of the particular computer the student is using. The e-Student system allows students authorized access to the teaching materials, tasks, exercises and instructions. Apart from this the system provides support in applying and producing seminar papers and various forms of knowledge testing (e-Blic, e-Test, e-Kviz). The SMSCentar and SAN system with smsCRM application (Customer Relationship Management via SMS) open up the possibilities for a number of information services for students and Faculty staff members based on interactive communication by means of SMS messages. Some three years ago, the m-Learning module was added to the e-Learning system of the Faculty in the form of interactive application for real-time information of students via mobile terminal devices, called FPZmobile. The basic idea was to develop an application that will provide accurate and up-to-date information related to the Faculty and the students’ achievements (seminars, exercises, quizzes, etc.) during their studying, in a form suitable for browsing on the mobile terminal devices interface, such as mobile phones, PDA devices or Smartphones. The modularity of such a system allows fast implementation of the new services according to the ideas and suggestions expressed both by the teaching and the non- teaching staff, and the students. In its five academic years of application, the e- Student module of the Faculty LMS has shown substantial positive shifts in the quality of studying. However, it also indicated substantial drawbacks both in the very processes of the system and in the technological obsoleteness and impossibilities of high-quality support of the Bologna Process and the program “Ishodi ucenja na Sveucilistu u Zagrebu” (eng. “Learning Results at the University of Zagreb”). Currently the system is used at all Faculty courses, 509 of them for 7489 students and 362 Faculty staff members. In the previous years the students used the system somewhat less than 850, 000 times and the teaching staff somewhat less than 50, 000 times. A large number of published teaching materials, as many as 5645 files, is still substantially lower than the files created and published the most important system users: the students! They published as many as 16, 000 topics for seminar papers and more than 15, 000 seminar papers. The freedom that they have in using the LMS is being slowly accepted by the students and it has been noted that the students have started to use LMS more and more in the period from midnight till 8 o’clock in the morning, and less and less in the period from 8 a.m. to 4 p.m. as presented in Table 1. Table 1: Percentage of accessing LMS system per times of day The negative sides of applying the Faculty LMS system and the drawbacks in the operation of the current system have to be reduced or completely eliminated in order to realize the desired level of studying quality. Therefore, a completely new system is to be designed and developed, based on the model presented in this paper. The new system will be adapted to the needs of studying according to the Bologna Process, harmonized with the project “Learning Results at the University of Zagreb”, the ISVU system, but also with the present trends in the technology of learning and communication among the students and between the students and the teachers. Moreover, the model proposed in this paper will provide guidelines for the development of the system according to the e- Learning 2.0 paradigm which encompasses all Web 2.0 tools in its operation such as Wiki, Blog, forums, social networking and others.
