To date, the 50 km/h General Urban Speed Limit (GUSL) has been implemented to some local residential streets in the City of Port Adelaide Enfield (hereafter referred to as Port Adelaide), South Australia as a Local Area Traffic Management (LATM) scheme since March 2003 aiming to reduce travel speeds and traffic volumes so as to enhance road safety and amenity of residential areas. Port Adelaide is located approximately nine kilometres away from the North-west of Adelaide Central Business District (CBD). There are major express highways and freight roads enclosing Port Adelaide, and within the boundaries is composed of many arterial and collector roads. All of these arterial roads and some major collector roads line in north-south direction. As a result of these geographical characteristics, Port Adelaide is a city covering the major direct routes for residents and major freight route for goods transport in the north-west suburbs. / However, one of the problems occurring in Port Adelaide seems to be characteristics of grid road networks lacking clear road hierarchy, which can be seen from many local streets connecting directly with nearby arterial and/or collector roads. Furthermore, as described previously Port Adelaide consists of many freight routes, arterial routes, and these characteristics cause another problem. Traffic is induced to divert to local streets, which are relatively straight, and uses them as an alternative route causing many problems to residents in the local area due to travel demands during rush hour. To this point, it can be seen that the 50 km/h GUSL scheme might not be as efficient as it should be in deterring through traffic since the implementation of traffic management has not covered a macro scale, which in this case is arterial roads forming a connective grid. / This study seeks to present the analysis of traffic data in terms of traffic volumes, mean speed and 85th percentile on three different local residential streets during weekday and soma crash data analysis is also done on two study streets. The expected results of this study may be taken as samples for further research in future. / Thesis (MTransportSysEngineering)--University of South Australia, 2006.
