Understanding the Impact of Street Patterns on Pedestrian Distribution: A Case Study in Tianjin, China

This paper investigates the impact of street pattern, metro stations, and density of urban functions on pedestrian distribution in Tianjin, China. Thirteen neighborhoods are selected from the city center and suburbs. Pedestrian and vehicle volumes are observed through detailed gate count from 703 street segments in these neighborhoods. Regression models are constructed to analyze the impact of the street pattern, points of interest (POIs), and vehicle and metro accessibility on pedestrian volumes in each neighborhood and across the city. The results show that when analyzing all neighborhoods together, local street connectivity and POIs had a strong influence on pedestrian distribution. Proximity to metro stations and vehicle accessibility had a minor impact. When analyzing each neighborhood separately, both local- and city-scale street patterns affect pedestrian distributions. These findings suggest that the street pattern provides a base layer for metro stations to attract both the emergence of active urban functions and pedestrian movement.

The Dilemma of Saudi Arabian Homes in Riyadh

The courtyard form of the traditional Arab house responded to both climate and the culture of its inhabitants. Islamic values, as well as socioeconomic factors, played crucial roles in the design. However, the mid-20th century marked the beginning of Saudi Arabia’s first rapid economic growth as a result of the discovery of oil; which dramatically increased the wealth and prosperity of the population, and resulted in new lifestyles. This period witnessed the introduction of the grid layout street pattern and the detached villa house. This type became the prevalent style in Saudi Arabia, the central province, and Riyadh in particular. While the traditional courtyard house more than satisfied cultural needs, increasingly it was viewed inappropriate for affluent 21st-century lifestyles. Yet this research confirmed that the villa style is creating fundamental problems for Saudi families. The theoretical framework is set in sustainability theory, and investigates the principles of home through human needs, place, and house. The methodology uses a survey strategy with questionnaires, interviews, and building analysis to determine which aspects of home are satisfied by each type. The dilemma is that Saudi families will not return to the courtyard type because it does not meet important requirements of status; whereas the villa type does not meet significant criteria such as privacy. The context is increasing climatic temperatures, which are making both types increasingly uncomfortable. This study highlights the need for a specific contemporary home style that would satisfy 21st-century aspirations, respect Islamic culture, and respond to changing climate.

Urban Form Elements and Urban Potentiality ( Literature Review)

Morphological theories shape the leading platform to theoretically and practically consider the assets connected with the emergence of the city, and its growth and development over time. In this paper, five elements of the urban form are typified: structure/tissue, plot, building, block, and the street pattern will be addressed. Understanding the urban form at the different levels within its ingredients could lead to shape a base launch of how to consider the potentiality of the development and sustainability of a particular area.

Analysis of a Flexible Transit Network in a Radial Street Pattern

Traditional transit systems are usually composed of fixed routes and stops, which are suitable in densely populated areas. This paper presents a reformulation of the flexible transit model developed by Nourbakhsh and Ouyang (2012) to adapt it to many low demand cities in the world, especially those characterized by radial street patterns. Unlike traditional ones, buses of the proposed transit network are allowed to traverse in a predetermined service area and their precise trajectories hinge on the exact locations of passengers. To identify the optimal topology structure of the flexible transit system, continuous approximation approaches are developed to explore the optimal value of design parameters of the whole system, defining the optimal network layout through minimizing its objective function. To exhibit its advantages, numerical experiments are conducted to compare the flexible transit system with its two variants. The results show that the flexible transit system proposed in this paper outperforms the other two variants. The higher the access cost is, the more it would tilt towards the flexible transit system with a significant margin. Besides, the flexible transit system in a radial pattern competes more effectively than that in a grid structure. This is encouraging because the proposed transit system can be applied in a number of real-world cases.

Effect of Community Road Infrastructure, Socio-Demographic and Street Pattern in Promoting Walking as Sustainable Transportation Mode

Background: Traffic demand is growing worldwide and the increased carbon emission from transport and travel activities is contributing to greenhouse gas emission and climate change. As the oil and gas capital of Canada, the city of Calgary has a very high carbon footprint per population and the reduction of automobile use is an important policy goal for the city. Walking, a part of active transportation promotes sustainable transportation initiative by reducing greenhouse gas emission. To encourage walking, favorable walking environment should be ensured which largely depends on street pattern and connectivity. However, the effect of street pattern on walking at community level was not explored much in previous studies, particularly at rapidly expanding city such as Calgary’s context. Aims and Objectives: The study identifies the effects of different neighborhood design and planning factors associated with the share of walking in work trips while controlling for differences in social economic characteristics of the neighborhood. Methods: A linear regression model was developed using community-level data from the 2011 census and the road infrastructure data of Calgary. Results: Our study finds that different street patterns and types of land use, length of train tracks, number of train stations and number of schools have significant effect on walking. Conclusion: Thus, different neighbourhood street patterns and land uses should be considered in the development of new communities for promoting active and sustainable transportation.

Transformation of Built form Characteristics in Agraharams

The culture and architecture are two interlinked concepts that help man to evoke uniqueness as an individual and a social being. A person’s or a community’s identity in a particular setting can be expressed through architecture. It is promising to create spaces with differences in spatial organization, street pattern, landscaping features, etc., according to the lifestyles, beliefs, rituals and customs of the inhabitants which finally becomes the identity of that particular place. But what happens to the identity of a place when all the inhabitants are migrants who left their homeland for better education or job opportunities and settled in a location where all social -cultural aspects are poles apart from theirs? This paper explores how the Architecture evokes the identity of the migrant communities in Kalpathy, Palakkad district, Kerala, without affecting the indigenous style of the location and the character of the total setting. This synthesis and metamorphosis of various religions and traditional practices has also been phenomenal in shaping our cities. Over the ages, many of these communities have been successful in maintaining uniformity in their social and Architectural fabric. This paper is intended towards highlighting the above mentioned aspects and how a unique culture gave rise to a new form of settlements known as Agraharams. Today, Agraharams are an epitome of how migrations driven by religious reasons, can shape the society as well as the built fabric of any city.

Linear Street Pattern in Urban Cities in Malaysia Influence Snatch Theft Crime Activities

Malaysia is one of the countries that is having rapid urbanization and the crime rates are getting worried by the Malaysian government. Thus, this paper objective is to identify the street pattern characteristics that influence the snatch theft activities. The character of the street pattern is identified by using the GIS to construct, determine andanalysethe area with high reported snatch theft cases. The result shows the area with the high number of snatch incidents is becoming a snatch theft hotspot area and the fragmented parallel type of street pattern influenced the snatch activities. eISSN: 2398-4287 © 2018.
