Abstract The state of art simulation modelling in managing traffic flow within a busy central business district (CBD) is demonstrated in this article. The objectives of this article were to; identify the existing condition of the street V/C ratios within the CBD area, and to develop various simulations modelling. The development of microscopic traffic simulations encompassing 5 streets within the CBD area in Pekanbaru, Indonesia using the PTV Vissim application was performed as a case study. The existing conditions of these 5 streets were very busy (Level of Service C and D) with on-street par

This work aims to study flow structures, heat and momentum transport in the wake of two staggered circular cylinders. In order to characterize heat transport in the flow, both cylinders were slightly heated so that heat generated could be treated as a passive scalar. The velocity and temperature fluctuations were simultaneously measured by traversing a three-wire (one cross-wire plus one cold wire) probe across the wake, along with a fixed cross-wire, which acted to provide a reference signal.

Streets perform a number of important functions and have a wide range of activities performed in them. There is a small but growing focus on streets as a more generalisable, atomised, and therefore more manageable unit of development and analysis than cities. Despite the public realm being one of the largest physical spaces on streets, the impact and potential of digitalisation projects on this realm is rarely considered. In this article, the smartness of a street is derived from the cyber-physical social infrastructure in the public realm, including data obtained from sensors, the interconnec

However, existing research has not incorporated economic knowledge into modeling, thus preventing application of the price elasticity of parking demand. In this study, proact

The number of periodic arrangements of point vortices – point vortex streets – in two-dimensional fluid flow that are stationary is known to be finite for a generic choice of vortex circulations. When all circulations are the same in absolute value, however, stationary vortex street configurations have been associated with the zeros of certain trigonometric polynomials containing free complex parameters. The presence of these parameters may prove useful in constructing point vortex models of shear layers and wakes. In this paper it is shown that such a continuum of stationary configurations ex

Dispersion is then controlled by turbulent mixing and mean flow transport through the network of streets. We consider mixing and transport in a long straight street, street intersections and then a network of streets connected by intersections. The mixing and transport in these system

The classical point-vortex model for a Kármán vortex street is linearly stable only for a single, isolated, marginally stable, case.

The method used is an analytic perturbation valid when the vortex areas are small, and applied using an automatic symbolic manipulator.

Analytical solutions are obtained for the evolution of wave number, mean centerline velocity, vortex velocity, and vortex “spacing ratio” as a function of downstream distance in a laminar vortex street. A simple criterion for the onset of oscillations in the far wake, which slightly precede vortex street initiation, is also obtained. All of these solutions account for the action of viscous diffusion in spreading the street, and they are found

Abstract:

Cultural heritage relating to the sky in the form of sundials, old observatories and the like, are commonly found in many cities in the Old World, but rarely in the New. This paper examines astronomical heritage embodied in the Barolo Palace in Buenos Aires. While references to Dante Alighieri and his poetry are scattered in streets, buildings and monuments around the Western world, in the city of Buenos Aires, the only street carrying Dante’s name is less than three blocks long and, appropriately, is a continuation of Virgilio street. A couple of Italian immigrants—a wealthy businessman, Luis

Abstract:

This project provides the simplest answer for power wastage. Conjointly the manual operation of the lighting system is totally replaced. In this project the LDR sensor is used to point a day/night time and also the microcontroller is used which is able to detect brightness of sunlight and the GSM module that acts on back side. The microcontroller Arduino board is employed as brain which is to manage the road lightweight system, The programming language used for developing the microcontroller is C language. The most important aim of the project is to avoid wasting the ability, by exploitation e

Abstract:

Streetism is a growing problem worldwide and Africa is one of the continents with the highest population of street children. United Nations International Children Emergency Fund (UNICEF) refers to street children as children whom the street, more than their family, becomes their real home. The recent statistics released by UNICEF revealed that States in the North-east and North-west regions of Nigeria have female primary net attendance rates of 47.7 per cent and 47.3 per cent, which shows that more than half of the girls in those parts of the country are not in school.

Abstract:

The noise pollution in tourist street view images is caused by various reasons. A major challenge that researchers have been facing is to find a way to effectively remove noise. Although in the past few decades people have proposed many methods of denoising tourist street scene images, the research on denoising technology of tourist street scene images is still not outdated. There is no doubt that it has become a basic and important research topic in the field of digital image processing. The evolutionary diffusion method based on partial differential equations is helpful to improve the qualit

Abstract:

Street view images are emerging as new street-level sources of urban environmental information. Accurate detection and quantification of urban air conditioners is crucial for evaluating the resilience of urban residential areas to heat wave disasters and formulating effective disaster prevention policies. Utilizing street view image data to predict the spatial coverage of urban air conditioners offers a simple and effective solution. However, detecting and accurately counting air conditioners in complex street-view environments remains challenging. This study introduced 3D parameter-free atten

Abstract The particle transport characteristics have a significant effect on the exposure of residents and pedestrians to traffic pollutants in the street canyon. Around the lakeside environment, the diffusion of water vapor affects the flow characteristics of the gas mixture, which has a considerable influence on particle transport in the street canyon. A computational domain containing water bodies from which droplets were emitted by evaporation, a lakeside avenue and architectural groups were constructed. The RNG k-ε turbulence model and discrete phase model were applied to study the veloci
