Toward Livable City Centers. Hebron as a Case Study
2012
City centers of Palestinian cities face many urban planning problems; the downtown city is mostly crowded especially in the last few years, because of the increasing population of the cities and the daily migration of the residents from the nearby villages. Everyone can touch the traffic jam problem, the bad quality of urban spaces, the lack of gardens and open spaces in the city center. All this affects negatively the citizens of the city, feeling uncomfortable in the city center. Thus, this study comes to light to draw guidelines to create a comfortable and livable urban environment for people in the city center and to develop the city center to a more environmental, functional, beautiful…
Performance Analysis of Basic Turbo-Roundabouts in Urban Context
2012
AbstractA turbo roundabout is a new type of canalized multilane intersection in which the physical separation between lanes helps to prevent side collisions when crossing the roundabout. This paper presents an estimation of capacity, delays and level of service of basic turbo roundabouts in undersaturation conditions, considering both vehicle flow and pedestrian traffic. The traffic performance model was developed by evaluating the capacity for each entry lane. Owing to the geometric features of the intersection, the total entry capacity is obtained by considering different values of the pedestrian impedance factor and degree of saturation at both the right-turn and left-turn lanes.
The accessibility of public urban spaces: walkability and ergonomic aspects
2013
Pedestrians can be ergonomically considered as workers into the socio-technical system of public urban space. Pedestrian targets can be defined as operations: the accessibility to a place characterized by services, commercial activities, enjoyment of leisure. Public space is a "universal" tool (differently from the ergonomic one), but it serves different user categories and enables different targets (movement, parking, social integration, etc..). The organization of public space should basically allow to perform users’ activities, but it has often been divided into a spatial and thematic compartments. From the twentieth century it was subservient to the dominion of the car, which strongly i…
