Roads are important components of landscapes; they fragment habitat, facilitate invasive species spread, alter hydrology, and influence patterns of land use. Previous research on the ecological impacts of roads may have underestimated their effect because currently available sources of road data do not include the full road network. We compared differences in road density and landscape pattern ...

Private road associations (PRAs) manage two thirds of the road network in Sweden. They manage the roads at less cost and with better results than the Government road agencies. In fact, the PRAs perform so well that some urban municipalities request the associations to manage the municipal roads which connect to the private roads. There are also PRAs that are responsible for ferry services, for ...

Roads have been a part of human landscapes for more than 40 centuries. During the 20th century, technological advances have increased our ability to construct new roads at unprecedented rates and into steeper terrain. In the last half of that century, an extensive network of roads has been constructed in forests and other wildlands to facilitate use and management of natural resources. They are...

One of the alleged justifications for government provision of roads is that the power of eminent domain is necessary in order to overcome holdout problems and obtain right-of-way properties (Goldstein 1987).1 After all, this argument continues, only the state has such power, so the private sector would be unable to supply the efficient amount of roads.2 In this article, I examine this market-fa...

In light of the increasing availability of commercial high-resolution imaging sensors, automatic interpretation tools are needed to extract road features. Currently, many approaches for road extraction are available, but it is acknowledged that there is no single method that would be successful in extracting all types of roads from any remotely sensed imagery. In this paper, a novel classificat...

Rural two-lane roads generally lack physical measures such as wide medians or barriers to separate opposing traffic flows. As a result, a major crash problem on these roads involves vehicles crossing the centerline and either sideswiping or striking the front ends of opposing vehicles. These types of opposing-direction crashes account for about 20% all fatal crashes on rural two-lane roads and ...

This study investigates the usage of road networks both within and outside of home jurisdictions (city (or town) and county of residence) by analyzing GPS data collected in the Minneapolis Saint Paul metropolitan area, which tracked volunteers’ travel behavior to determine which roads (and thus which class of roads) users chose to accommodate their travel needs. More than half of the travel on ...

This paper analyses which factors can explain the planned funding for 83 different stretches of roads in the Norwegian national road network during the ten-year period from 2010 to 2019. Previous studies have focused on the extent to which Norwegian politicians use the results of cost-benefit analyses when they prioritise various road projects. In contrast, we analyse how road characteristics, ...

An automatic procedure is developed for detection of changes between an existing road database and a newly registered satellite image, rectified to an orthophoto. The approach uses the existing database to force the detection and delineation of the corresponding road network in the image. Each road segment is handled separately during the comparison between the image and the database as the pos...

This paper explores integrated pricing of electricity and roads enabled by wireless power transfer technology. We envision that high-power, high-efficiency wireless power transfer technologies are mature in the near future, which electrify roads to be charging infrastructures. The prices of electricity at electrified roads will affect electric vehicles’ route choices while the energy requiremen...
