Various surveys have been carried out in narrow waters throughout the world and provide data on the traffic volume, traffic density, velocity distributions of ships, &c. Although these surveys certainly contribute to the safety of local navigation they do not give any information on traffic movements between terminal points in a marine traffic system. There are a few papers on voyage distribution based on traffic surveys, statistical reports or questionnaires to mariners and also a few based on radar observation, including one in Osaka Bay in Japan which was carried out by the traffic research group of the Kobe University of Mercantile Marine and Nautical Technical College.

This paper addresses the fields of social and service design in development contexts, practice-based and constructive design research. A framework for social design for services will be explored through the survey of existing literature, specifically by drawing on eight doctoral theses that were produced by the World Design research group. The work of World Design researcher-designers was guided by a strong ethos of social and service design for development in marginalised communities. The paper also draws on a case study in Namibia and South Africa titled ‘My Dream World’. This case study presents a good example of how the social design for services framework functions in practice during experimentation and research in the field. The social design for services framework transfers the World Design group’s research results into practical action, providing a tool for the facilitation of design and research processes for sustainable development in marginal contexts.

ABSTRACTIndonesia harbours a high diversity of cetaceans, yet effective conservation is hampered by a lack of knowledge about cetacean spatial distribution and habitat preferences. This study aims to address this knowledge gap at an adequate resolution to support national cetacean conservation and management planning. Maximum Entropy (Maxent) modelling was used to map the distribution of 15 selected cetacean species in seven areas within Indonesian waters using recent cetacean presence datasets as well as environmental predictors (topographic and oceanographic variables). We then combined the individual species suitable habitat maps and overlaid them with provincial marine spatial planning (MSP) jurisdictions, marine protected areas (MPAs), oil and gas contract areas, and marine traffic density. Our results reflect a great heterogeneity in distribution among species and within species among different locations. This heterogeneity reflects an interrelated influence of topographic variables and oceanographic processes on the distribution of cetacean species. Bathymetry, distance to-coast and −200m isobaths, and Chl and SST were important variables influencing distribution of most species in many regions. Areas rich in species were mainly related to high coastal or insular-reef complexity, representing high productivity and upwelling-modified waters. Although some important suitable habitats currently fall within MPAs, other areas are not and overlap with oil and gas exploration activities and marine traffic, indicating potentially high risk areas for cetaceans. The results of this study can support national cetacean conservation and management planning, and be used to reduce or avoid adverse anthropogenic threats. We advise considering currently unprotected suitable cetacean habitats in MPA and MSP development.

Intelligent Traffic System

The overall automobile industry in the world has encountered remarkable growth, vehicle increases traffic density which seems in increasing accidents. Thus the automobile Industries, researchers and government are shifted their focus in the direction of improving on-road safety instead of improving the condition of the roads. The top development in the wireless technologies emerged a diverse new sort of networks together with Vehicular Ad Hoc Network, VANET uses wireless network technology wherein driving gets safer by inter-vehicle communication. Using this technology, automobiles are not only envisioned to contact between each other, but also to get information from and transmit data to infrastructural units. In this, we have discussed about the traits and applications of VANET along with routing protocols. The routing protocols states how two communiqué individuals interchange information which covers the methods to generate path, to retain the route or improve from routing fiasco. In this we have explained two routing protocols i.e. Topology based routing protocol and Geographic (Position-based) routing protocol with its types, advantages and disadvantages as well as we have examined the performance of AODV and GPSR routing protocols using quality matrix.

In the study of ocean engineering, marine traffic is referring to the study of the pattern of the density of ships within the particular boundaries at certain periods. The Port Klang and Straits of Malacca are known for one of the heaviest traffics in Malaysia and the world. The study of traffic within this area is important, because it enables ships to avoid traffic congestion that might happen. Thus, this study is mainly aimed at   predicting or forecasting the density of the ships using the route through this waterway by using quantitative methods which are time-series models and the associative models from the Automatic Identification System (AIS) data. The moving averages, weight moving average, and exponential smoothing for the time series model and associative model have used multiple regression. The results show an exponential smoothing alpha 0.8 and give the lowest MAPE as 20.701%, thereby making this method to be the best in forecasting the future traffic density among the method categories.

The increase in traffic volume will cause a decrease in service due to decreased road capacity due to an increase in side constraints and due to the increase in traffic volume itself, which will ultimately cause the level of road saturation to increase. The situation occurred in the Umasukaer road section of the Malacca Regency. Therefore it is necessary to address improvements in the quality of the road in order to meet the feasibility of transportation facilities by taking into account the existing technical requirements. The results of planning found that through the 2015 LHR survey data with a prediction of an increase in traffic density of 6% per year, the LHR was obtained with a planned age of 7 years = 2540.7 vehicles/day/department and a 20-year plan life LHR = 5419.1 ked/day / major. The results of a gradual construction planning pavement study can be concluded that the planning model that has been designed is effective in strengthening road construction in accordance with existing technical requirements and efficient in terms of financing. The final results of gradual construction pavement thickness results are: Ashburton thickness (MS 744) = 8 cm, Ashburton (MS 744) = 13 cm, broken stone (CBR 100) = 20 cm, Sirtu (CBR 50) = 10 cm and CBR subgrade 5%. Pertambahan volume lalu lintas akan menyebabkan penurunan layanan diakibatkan menurunnya kapasitas jalan karena adanya peningkatan hambatan samping maupun karena beratambahnya volume lalu lintas itu sendiri yang pada akhirnya akan meyebabkan tingkat kejenuhan jalan meningkat. Keadaan tersebut terjadi ruas jalan Umasukaer Kabupaten Malaka, oleh karena itu perlu adanya penanganan perbaikan kualitas jalan agar memenuhi segi kelayakan sarana transportasi dengan memperhatikan syarat-syarat teknik yang ada. Hasil perencanaan didapatkan bahwa melalui data survey LHR tahun 2015 dengan prediksi peningkatan kepadatan lalu lintas sebesar 6% pertahun maka didapatkan LHR dengan umur rencana 7 tahun = 2540,7 kend/hr/jurusan dan LHR umur rencana 20 tahun = 5419,1 ked/hr/jurusan. Hasil studi perencanaan perkerasan konstruksi bertahap dapat diambil kesimpulan bahwa model perencaaan yang telah dirancang efektif dalam memperkerasa konstruksi jalan sesuai dengan syarat teknis yang ada serta efisien dalam hal pembiayaan. Hasil akhir tebal perkerasan konstruksi bertahap diperoleh hasil: Ketebalan Asbuton (MS 744) = 8 cm, Asbuton (MS 744) = 13 cm, batu pecah (CBR 100) = 20 cm, Sirtu (CBR 50) = 10 cm dan CBR tanah dasar 5%.
