A good simulation environment will facilitate motion planning algorithm development for urban autonomous driving. The first requirement of such a simulator is to be able to replicate a complex urban environment, including road network, curb, general objects, etc. The second requirement is to simulate a realistic host vehicle, which includes perception, control and vehicle dynamics, to recreate ...

information and communication technology (ict) has transformed how we live our lives and the way we interact in different contexts. benefits of ict and its upcoming efficiencies (i.e. energy efficiency) are becoming the heart of many public services’ reforms which have influenced the time, distance and space concepts. at present, not only there is a lack of clarity about what high-quality ictba...

Complex situations of today's life have led to the complexity of urban life issues and not pay attention to the quality of life. Studies in this field are increasingly gaining the attention of urban planners and policymakers due to its usefulness in assessing and monitoring public policies, also they can use as effective tools in urban management and planning. This study investigated the QOL in...

the earth is a stable feature but it is diminished due to different factors including: the extension and development of cities, emerging of villages and rural areas with the physical texture of cities, the spreading of industrial units and population growth, changing the patterns of land use and lack of good management. this paper is concerned with the global and national perspective of these p...

We describe a practical path-planning algorithm that generates smooth paths for an autonomous vehicle operating in an unknown environment, where obstacles are detected online by the robot’s sensors. This work was motivated by and experimentally validated in the 2007 DARPA Urban Challenge, where robotic vehicles had to autonomously navigate parking lots. Our approach has two main steps. The firs...

experiences from urban development plans and assessments of their concrete and tangible results in the past decades indicate lack of adequate success of our urbanization system to responding needs of our citizens. this has resulted in need to find a fundamental solution to transforming the centralized system into decentralized. recent changes in regard to a change of approach from master plan t...

this study investigates the application of landscape ecology in planning and design of urban ecological systems. the ecological approach to landscape planning and the concepts of designing and implementing ecological systems have gained increasing attention in the last two decades. however, the ecological systems of urban environment need more research to consider built and natural patches and ...

As urban populations around the world continue to grow, achieving sustainable urban water supply is becoming crucial in order to meet increasing demand. Cyclical drought and climate change have placed further strain on water supplies and it is therefore necessary to plan to ensure the sustainability of water supply systems at a regional scale. Water supply sustainability planning (WSSP) necessi...
