    ICT as a tool for Development of Traffic Control Systems 
    (2011) Ndyetabura, Hamisi Y.; Mwinyiwiwa, Bakari M. M.; Mvungi, Nerey. H.; Mfinanga, David A.
    The application of Intelligent Transportation Systems (ITS) in Intelligent Traffic Control System (ITCS), is expected to improve the performance of road transportation significantly. Public policy makers, among others, are therefore increasingly interested in the implementation possibilities of these systems. However, current knowledge ITS implementation issues is poor with respect to technological requirements for its implementation. The contribution of ITS to general transport policy goals and the

    Intrussion Detection by Penetration Test in an Organization Network
    (IEEE xplore Digital Library, 2009-01-14) Ndyetabura, Hamisi Y.; Mvungi, Nerey, H.; Mfinanga, David A.; Mwinyiwiwa, Bakari M. M.
    This paper presents a study made on network security in an organization's local area network (LAN). Intrusion detection test in a campus network was performed using penetration test methods and the results analyzed. The objectives were to identify different form of network attacks and methods used to capture the hacking. During the study, the risks and attacks caused by hackers to the network were evaluated. The results obtained are seen as a good indicator of the security state of the network. Hence, an organization network that responds well to penetration test can be given a certificate. Such certificate will provide a positive sign and confidence to the network users. The study was conducted in a dynamic situation by doing experiments during different periods of time. The case study was a campus LAN, The network administrator permitted network information like internet protocol (IP) address to be gathered and analyzed and to performed the penetration test that enabled , hackers and attackers methods to be dentified. It was realized that 90% of network the users has no fear of the network security risk inspite of the finding that network security rating of the case study is at 50 percent.

    Prospects of Pre-timed Arterial Traffic Control Systems in City Roads of a Typical Developing Country: A Case Study of Dar es Salaam City
    (IEEE xplore Digital Library, 2011-01-14) Ndyetabura, Hamisi Y.; Mvungi, Nerey, H.; Mfinanga, David A.; Mwinyiwiwa, Bakari M. M.
    This paper looks into prospects of pre-timed arterial traffic control systems for cities with limited infrastructures. The methodologies for designing a pre-timed arterial traffic controller system were researched. A prototype designed and implemented in Field Programmable Gate Arrays (FPGA) is presented. Dar es Salaam Roads have been used to provide data for the design and implementation whereby the neighboring road intersections within a logically computed radius of less than 250m qualified for pre-timed arterial traffic controller. One intersection is a master and the remaining ones act as slaves. Using Very High Speed Hardware Descriptive Language (VHDL), an algorithm has been developed for coordinating adjacent traffic signals along the arterial roads. The use of VHDL enabled the algorithm to be implemented and tested in Xilinx Spartan 2E Field Programmable Gate Array (FPGA) that functioned and served the purpose of real-time simulation of Arterial Traffic Controller.
