Coastal cities in the Adriatic and Ionian region are studied according to three evolution stages spanning from the end of eighteenth century to the present. The urban growth during this period has occurred according to successive additions without significant modifications of inner city areas. Street networks are represented with linear maps and are analyzed according to measures of connectivit...

While maps exist for most urban areas, there are many locations where the information is not accurate, it may be out of date, or it may be incomplete or of insufficient resolution for the applications. Many difficult problems remain in automated cartography. One of them is the extraction of a street grid in an urban environment. Much of the work on road detection has concentrated on either low ...

The newly found interest of private developers and communities to bring back the urban Main Street has brought with it questions about what the Main Street should be. Private developers see the inner city as the next frontier for retail development. Communities are attempting to redevelop their districts both with and without private involvement. The goals of each approach are significantly dif...

A three-dimensional numerical time-domain model based on the linearised Euler equation is applied to idealised urban situations with elongated, isolated buildings beside a straight street with sound emissions. The paper aims at the investigation of principle relationships between the source– receiver geometry (street and building facades) and sound propagation under the consideration of ground ...

This paper proposes a novel generalisation model for selecting characteristic streets in an urban street network. This model retains the central structure of a street network, it relies on a structural representation of a street network using graph principles where vertices represent named streets and links represent street intersections. Based on this representation, so-called connectivity gra...

New streams of data enable us to associate physical objects with rich multi-dimensional data on the urban environment. This study presents how open data integration can contribute to deeper insights into urban ecology. We analyze street trees in New York City (NYC) with cross-domain data integration methods by combining crowd-sourced tree census data which includes geolocation, species, size, a...

In this paper we report an analysis of 118 urban areas sampled from the 12 largest metropolitan regions in the US. We deal with familiar measures of block size, street density, intersection density and distance between intersections. We also introduce two new variables, Reach and Directional Distance. Reach is the aggregate street length that can be accessed from the midpoint of each road segme...

Current Internet-inspired mapping data are in the form of street maps, orthophotos, 3D models or street-side images and serve to support mostly search and navigation. Yet the only mapping data that currently can really be searched are the street maps via their addresses and coordinates. The orthophotos, 3D models and street-side images represent predominantly “eye candy” with little added value...

An effective surveillance system is required to reduce pesticide exposures and poisonings, especially from street pesticides (illegal, unlabelled, and decanted agricultural pesticides used predominately for urban household purposes). Poisoning from any pesticide class, not only organophosphates, constitutes a medically notifiable condition in South Africa. Current practice, however, is to repor...

While traditional street design relied upon segregating vehicles and pedestrians in urban areas to ensure smooth traffic flow, urban planners and traffic engineers are gradually moving away from it. Instead, under the more modern concept of integrated street design, more space and freedom of action is provided to pedestrians, the needs of whom were previously omitted. An example space to have u...
