Urban sprawl, or the unplanned and uncontrolled spreading out of built-up areas in Zaria urban area causes problems of congestion, poor urban basic infrastructure delivery and poor urban planning. This paper analyzed the pattern and implications of urban sprawl using GIS and Remote sensing as an improved approach to analyze and explain sprawling beyond the traditional spatial or cartographic ma...

Path planning of mobile robot in dynamic environment is one of the most challenging issues. To be more specific, path planning in multi-obstacle avoidance environment is defined as: given a vehicle A and a target G that are moving, planning a trajectory that will allow the vehicle to catch the target satisfy some specified constrains while avoiding obstacle O, and each of the obstacles can be e...

The ability to detect and navigate drivable road surfaces is an important research area in autonomous navigation for use in autonomous vehicles. In this paper, a probabilistic computer vision algorithm for segmentation of tarred road surfaces is developed. Using a calibrated camera, a projection of a local obstacle map is then laid over the segmented image and an estimate is made of the likelih...

The autonomous vehicle is an automated system equipped with features like environment perception, decision-making, motion planning, and control and execution technology. Navigating in an unstructured and complex environment is a huge challenge for autonomous vehicles, due to the irregular shape of road, the requirement of real-time planning, and the nonholonomic constraints of vehicle. This pap...

Increasing availability of vehicle GPS data has created potentially transformative opportunities for tra c management, route planning and other location-based services. Critical to the utility of the data is their accuracy. Map-matching is the process of improving the accuracy by aligning GPS data with the road network. In this paper, we propose a purely probabilistic approach to map-matching b...

this article studies the effects of weather on road accidents in saqqez - sanandaj road. saqqez- sanandaj road’s length is 187 km and it is one of the main hazardous roads of the area. in this study, the distribution map of road accidents and the probability of accidents were prepared under every climatic condition (i.e., snowy, frozen, rainy, foggy, and sunny). a database of road accidents o...

This issue of the journal seeks to accelerate interest in research on family planning services and uptake, and behavioral and population outcomes, by sharing findings from studies recently conducted on the continent and presented at the International Family Planning Conference held in Kampala, Uganda, between November 15 and 18, 2009. There are three main themes across the studies: 1) individua...
