Streets function as the place for interaction and communication, transportation, social and commercial activities for the general public. The concept of 'complete street' is gaining popularity worldwide. This study has assessed the current conditions of various functional streets' categories in selected neighborhoods in Riyadh to examine the applicability of complete streets concept on streets within and outside neighborhoods. Recent policy shift in Saudi Arabia includes huge government outlays for public transportation, humanizing neighborhoods, promoting walking as a healthy lifestyle and rising fuel prices would create a positive atmosphere for the implementation of complete streets' concept. Reclaiming streets to all users would be an important objective especially in cities that have been characterized as auto-dependent for decades. There is a need to reprioritize community development objectives for a more sustainable and livable environment.

Children's mobility in terms of frequencies, challenges, and solutions have a direct impact on their lifestyle. The study aims to assess the notion of children's mobility within urban neighborhoods in Riyadh, Saudi Arabia. It further examines the effects of school proximity and age/gender of children on their mobility patterns within Riyadh's neighborhoods. A sample questionnaire for school going students are used to assess their mobility patterns. The study showed that age and gender have significant effects on mobility, which seemed to increase among males and older boys in particular. Although automobiles are still the dominant mode for traveling, there are significant differences in walking trips in favor of male students to neighborhood facilities including schools. The study concluded that there is a need for Saudi cities to adopt aggressive policies that promote walking for children and adults within and between nearby neighborhoods.

Universities worldwide face growing problems of traffic congestion and parking shortages due to the increased usage of private automobiles and the decline of public and non-motorized transport systems. This paper addresses transportation system challenges facing university campuses. As a case study, it addresses King Saud University, Saudi Arabia. The fast growth of King Saud University Campus during the last 5 years had profound impacts on its transportation system. The study adopts two methodological approaches. Theoretically it reviews and analyzes several studies and published reports related to KSU campus and other international campuses. The empirical approach emphasizes the analysis of field data gathered by relevant KSU departments. The paper intends to analyze changes in traffic conditions and transportation systems within the KSUC and draw conclusions on the current and future issues facing the campus and other similar campuses. For a more sustainable campus, KSU has to adopt a balanced transportation system. The new system should not be based solely on improving vehicular circulation and parking provisions. It should enhance public transportation and pedestrian environment within the campus. The university should embark new sustainable policies to curtail demand on vehicular trips and parking spaces and increasingly rely on environmental-friendly modes of travel.
