Roads play a significant part of economic development. Due to financial constraints, in many developing countries like Botswana, there are large networks unpaved roads. The major detriment effect or gravel roads is dust emissions. Dust affects the climate change which turn increases generation dust. This has huge impact on human health risen great concern. best solution mitigate emission from s...

The increasing proliferation of digital technologies is transforming economies in many ways. This is particularly true in consumer-facing industries where the emergence of digital services is enabling novel value propositions, closer consumer relationships and greater automation of consumer-facing business processes.2 These digital services are providing value-creating consumer interactions. Fo...

Most of the roads in Iraq are paved using Hot Mix Asphalt (HMA) which is consisted aggregates, asphalt cement and filler. In this study a laboratory investigation conducted two types widely used fillers highly locally available. Four different proportions are. Filler four proportion (i.e., 1.9%, 2.5%, 3.5%, 4.5%) by total weight aggregate for both used. These were blended with penetration 40/50...

As one type of pavement distresses, potholes are important clues indicating structural defects of the asphalt road, and accurately detecting these potholes is one of important tasks for determining proper strategies of asphalt-surfaced pavement maintenance and rehabilitation. However, manually detecting and evaluating methods are expensive and timeconsuming. Thus, several efforts have been made...

The ALVINN (Autonomous Land Vehicle In a Neural Network) project addresses the problem of training artificial neural networks in real time to perform difficult perception tasks. ALVINN ,is a back-propagation network that uses inputs from a video camera and an imaging laser rangefinder to drive the CMU Navlab, a modified Chevy van. This paper describes training techniques which allow ALVINN to l...

The recycling of printed circuit boards in Guiyu, China, a village intensely involved in e-waste processing, may present a significant environmental and human health risk. To evaluate the extent of heavy metals (Cd, Co, Cr, Cu, Ni, Pb, Zn) contamination from printed circuit board recycling, surface dust samples were collected from recycling workshops, adjacent roads, a schoolyard, and an outdoo...

We present a new application of computer vision: continuous measurement of the geometrical visibility range on inter-urban roads, solely based on a monocular image acquisition system. To tackle this problem, we propose first a road segmentation scheme based on a Parzenwindowing of a color feature space with an original update that allows us to cope with heterogeneously paved-roads, shadows and ...

Abstract The road is the most commonly used means of transportation and serves as a country’s arteries, so it extremely important to keep roads in good condition. Potholes that happen appear must be repaired Spotting potholes on difficult, especially country like India where stretch millions kilometres across country. Therefore, there need automate identification with high speed real-time preci...

The road system built during the Roman Empire continues to have a significant impact on modern infrastructure in Italy. This paper examines historical influence of roads development Italy's motorways and railways. empirical analysis demonstrates how Italian transport largely follows path consular trajectories established by network roads. These ancient roads, being paved connecting extremes pen...

Fugitive dust is a serious threat to unpaved road users from safety and health point of view. Dust suppressing materials or suppressants are often employed lower the fugitive dust. Currently, many commercially available being developed for various applications. The performance these depends on their physical chemical properties, application frequency rates, soil type, wind speed, atmospheric co...
