It is observed that the power consumption of road lighting is increased with the length of trafficable road in Hong Kong. The energy used in road lighting is increasing, which means that the greenhouse gases (GHGs) emitted from power plant for generating electricity for road lighting is at the same time increasing. To compare the performance of light emitted diode (LED) road lighting with road lighting of other lamp sources, literature review, life cycle assessment (LCA) and technical assessment are adopted to give an overall comparison. This research focuses more on the environmental impacts of road lighting. LCA is adopted in order to give a comprehensive view on the environmental impact of road lighting. A total of 3 different lamp sources are compared: high pressure sodium (HPS) lamp, induction lamp and light emitted diode (LED) lamp. From the model result, it is found that due to the low power consumption and long life time, LED and induction lamp road lighting gives generally less environmental impact than HPS road lighting. As induction lamp has a longer life span than LED, the environmental impact of induction lamp road lighting is found slightly less than that of LED road lighting. Taking account the future development in LED technology, leading to longer life time, higher efficacy and lower production cost, LED road lighting is expected to be a replacement for road lighting in Hong Kong for the future. / published_or_final_version / Environmental Management / Master / Master of Science in Environmental Management

Information about roads system is one of application branches of geographical information system. In my work I have explored some programmes that are created in Lithuania and have the similar purpose. During this analysis there was cleared up that we don‘t obtain the desirable result with these systems. There were discussed GIS creation instruments and given reasons to choice AutoDesk programmes package. During this work there was created a project that functions meet the users’ requirements. There are pictured roads system and formed menu for laying out road constructions, generation of reports, withdrawal of co-ordinations to textual file. The external data base that can do analysis of roads and their constructions is connected to roads system. The experimental research of system shows that it works and could be used practically. For graphic data accuracy (error till 1.5 meter) we copy the information from a map and put it to GPS (global positioning system) equipment – in that way inventory and then analysis of roads and roads constructions are done. This project isn‘t completed. There is lack of information about attribute base of roads and roads constructions, so there is a need to improve attribution part. System functions could be developed by integrating it to „LAKIS“ (Lithuanian automobile roads information system) programme that was used in the work. That way would be a very important step forward but this part belongs to a lot of people wishes to collaborate... [to full text]
