INTRODUCTION Rural Road connectivity is a key component of rural development, since it promotes access to economic and social services, thereby generating increased agricultural productivity, non-agriculture employment as well as non-agricultural productivity, which in turn expands rural growth opportunities and real income through which poverty can be reduced. A study (Fan et al. 1999) carried...

Given $N$ cities and $R<N^2 - N$ directed (unidirectional/one way) roads does there exist a tour of all $N$ cities stopping at each city exactly once using the given roads (a Hamiltonian cycle)? This Hamiltonian cycle problem (HCP) is an NP-complete problem, for which there is no known polynomial time solution algorithm. The HCP has important practical applications, for example, to logistical p...

This paper presents a novel routine to detect the changes of main roads with airborne images of medium-scale of 1:10,000. It mainly focuses on the changes detection of primary streets not the extraction of roads though it sounds an essential step. Here comes the brief work flows of this method: first, auto dodging the original image with Wallis Filter (Deren Li, 2006) as the pretreatment, secon...

Roads are significant objects of an infrastructure and the extraction of roads from aerial and satellite images are important for different applications such as automated map generation and change detection. Roads are also important to detect other structures such as buildings and urban areas. In this paper, the road extraction approach is based on Active Contour Models for 1-meter resolution g...

Resolving the problem of congestion roads is very challenging; however a way out of this problem will bring about many most wanted results like helping people not late to work; deliveries arrive on time and more. One approach to confront this task is letting the drivers be aware of congested roads online, so the drivers will be able to avoid going through the congested roads. This paper propose...

This study evaluates the impact of the 65-mph speed limit on traffic safety. Using data for the years 1981 to 1995 for all 50 states, a pooled time series analysis is conducted. Separate models are estimated for state fatality rates on four categories of roads: rural interstate highways, rural noninterstate roads, all roads except for rural interstate highways, and all roads. It is reported tha...
