The design of efficient routing algorithms is an important issue in dense ad hoc wireless networks. Previous work has shown that benefits can be achieved through the creation of a set of data “highways” that carry packets across the network, from source(s) to sink(s). Current approaches to the design of these highways however require a–priori knowledge of the global network topology, with conse...

BACKGROUND Regular physical activity can help prevent chronic diseases, yet only half of US adults meet national physical activity guidelines. One barrier to physical activity is a lack of safe places to be active, such as bike paths and sidewalks. Complete Streets, streets designed to enable safe access for all users, can help provide safe places for activity. COMMUNITY CONTEXT This communit...

Through utilizing US state-level data at annual frequency from 1976 to 2008, this paper documents a causal effect of infrastructure investments, specifically public spending on highways, on income inequality. The number of seats in the US House of Representatives Committee On Appropriations serves as a valid instrument to identify quasi-random variations in state-level spending on highways. Whe...

The article presents the results of soundscape assessments conducted in urban parks Silesian Voivodeship. Voivodeship is characterised by a high degree industrialisation and greatest population density Poland. studies were all cities voivodeship with populations over 100,000 citizens. This selection was determined based on acoustic maps that are prepared for citizens as required law, fact role ...

We present work in progress on the development of a partially-automated system for interpretation of map images. The principal aim of our project is to demonstrate that an adaptive system can decrease operator intervention with increasing conversion volume. The extracted information is evaluated against an established database, and a cost model is constructed to evaluate the entire conversion t...

Tolls are a recurring but not continuous feature in major highway financing policy in Spain. User tolls were the model used to finance the first expansion of the highway network, in the 60’s and early 70’s. The second wave of the highway network expansion took place in the late 80’s and early 90’s. The public budget was the usual source of funds used to pay for the highways built in this period...

In this paper, a new practice-ready method for the real-time estimation of traffic conditions and travel times on highways is introduced. First, after principal component analysis, observation days historical dataset are clustered. Two different methods compared: Gaussian Mixture Model k-means algorithm. The clustering results reveal that congestion maps same group have substantial similarity i...

The work is aimed at studying the intensity of roads in Republic Kazakhstan (for example, Almaty-Kapshagai-Taldykorgan highway) and improving traffic management system. development a single economic space country largely depends on level transport infrastructure each region. In this regard, need to strengthen interaction central local executive bodies issues state regulation activities, while m...
