In this paper a realistic cellular automata model is proposed to simulate traffic flow at single-lane roundabouts. The proposed model is built on fine grid Cellular Automata (CA), so it is able to simulate actual traffic flow more realistically. Several important novel features are employed in our model. Firstly, 1.5-second rule is used for the headway (=distance /speed) in carfollowing process...

The continuous improvement of the information systems of organizations that work toward the control of stray dog and cat populations facilitates the implementation of programs aimed at reducing the number of animals that roam free in public streets. This study aimed to present techniques to improve the understanding of the spatial distribution of stray dogs and cats and of people who adopt thes...

We study the impact of global traffic light control strategies in a recently proposed cellular automaton model for vehicular traffic in city networks. The model combines basic ideas of the Biham-Middleton-Levine model for city traffic and the Nagel-Schreckenberg model for highway traffic. The city network has a simple square lattice geometry. All streets and intersections are treated equally, i...

This study introduces a comprehensive representation of the public domain in urban space, discusses the role of machine learning techniques in such a representation, and presents a preliminary experiment. We define "public domain" as all places that people actually perceive as public space— traditionally identified spaces such as streets, squares, parks, as well as privately managed collective ...

We define an elliptic equation for Hermitian metrics which is related to the Einstein condition. Solutions to this equation are closely related to Kähler-Einstein metrics, and are automatically Kähler-Einstein when a certain non-positive condition is satisfied by c1(M). Given this, a natural flow equation arises taking Hermitian metrics to Kähler metrics. We prove short time existence and regul...

Urban landscapes form the main parts of the city. One of these spaces is urban streets, in whichsocial interactions and urban vitality reach its maximum quality and quantity. One of the principles and properties ofurban landscape design is its intelligibility. A viewer who takes a look at an intelligible city and knows it can attract newemotional manifestations of city without damaging its orig...

This paper describes a methodology for estimating transit walk accessibility that overcomes the problems associated with barriers and uneven distribution of population, and a methodology for forecasting transit walk accessibility for a future year given forecast population and employment data, transit route information, and street configuration type. Comparison of the results with those from th...
