This paper is based on reviewing the literature in the past 10 years on the drivers of land use and land cover change (LULCC) in urban areas. It combines quantitative and qualitative keyword analysis of papers drawn out from the Scopus database. The analysis is primarily based on the number of mentions of keywords in the titles and abstracts of the papers, in addition to the number of keywords appearing in the papers. On the basis of content analysis, a three-level structural categorization of the driving factors was developed. These are presented in a schematic diagram, where the contextual factors are shown as influencing economic and financial factors and policy and regulation, which in turn influences transportation investments and availability, and industrial and residential location choices. Transportation availability was seen as the most frequent factor identified in the literature. This research contends that LULCC is mostly determined by interactions among these four themes in a three-level structure, and on this basis, a model is presented that illustrates LULCC drivers based on local circumstances across the globe.

Due to valuable global experiences regarding Transit Oriented Development (TOD) as a context-sensitive strategy, updating the planning dimensions and even post-performance imperfections is inevitable by which reinforcing new urban plans could be dramatically pursued. Therefore, the present study aimed to highlight the most significant dimensions of transit-oriented urban planning all over the world. To this end, relevant qualitative studies were systematically reviewed through a Qualitative Meta-synthesis study. A total of 17 peer-reviewed articles and complementary databases searched during May-August 2018 led to a number of 6522 records among which 23 cases met the eligibility criteria and quality appraisal for inclusion in the final list. Then, the results were interpreted by using qualitative content analysis and a development-driven model was drawn by a classification as the general TOD planning themes including place development, policy development, process development, and sustainable development. Based on the results of the study, 30 planning dimensions pertinent to TOD were listed. The results helped retrieve and collect the up-to-date dimensions and interpret the changes appeared during the decades of planning.Resumen  Debido a las valiosas experiencias globales realizadas en Desarrollo Orientado al Transporte Sostenible (DOTS)’, una estrategia sensible al contexto es inevitable actualizar la planificación e incluso las imperfecciones posteriores al desempeño, a las que se podría seguir reforzando los nuevos planes urbanos. Este estudio pretende resaltar las dimensiones más importantes para la planificación urbana orientada al tránsito en todo el mundo. Para ello, las investigaciones cualitativas relevantes se revisarán sistemáticamente a través de un estudio de meta-síntesis cualitativa (QMS). La búsqueda de 17 artículos revisados por pares y bases de datos complementarias de mayo a agosto de 2018 dio lugar a 6522 registros, de los cuales 23 cumplieron con los criterios de elegibilidad y la evaluación de calidad para estar en la lista final. Usando el análisis de contenido cualitativo, los resultados se interpretaron, y por una clasificación, se elaboró un modelo impulsado por el desarrollo como temas generales de planificación de DOTS, a saber, Desarrollo del desarrollo, Desarrollo de políticas, Desarrollo de procesos y Desarrollo sostenible. Con respecto a los hallazgos del estudio, se enumeran 30 dimensiones de planificación relevantes para DOTS. Los resultados ayudarán a recuperar y recopilar las dimensiones actualizadas y a interpretar los cambios

The goal of this study was to find out how suitable the existing design of urban forms is for adopting transit-oriented development (TOD) basic ideas. Within a major metropolis and a medium-sized city, three varieties of Iranian urban fabric (historic, transitional, and modern) around transit stations were selected using the case study research technique. Then, for two sizes of station areas (macro) and street scales (micro), several TOD design dimensions were evaluated. The results of the comparative research indicated that Iranian cities offer greater chances for TOD design in inner urban areas (including historical and transitional urban forms), whereas microscale characteristics are less reliant on the kind of urban form.
