MMLOS-based study of central streets: re-planning Beyhaq St., Sabzevar, Iran

: Planners have been seeking new urban solutions to increase the presence of citizens once again without any constraints to ensure a safe urban space and provide equal opportunities for using transportation modes. Multi-modal level of service, used as a tool for analyzing complete streets, facilitates the creation of a fair and equal environment for all users and the enhancements of public safety and security against road accidents. The main purpose of this study is to resolve the problems of urban space allocation of central streets to all users in cities of middle-income countries that lie in historical context. The analysis is based on the multi-modal level of service indicators and is influenced by efficient plans and global policy strengths. In this regard, identifying the characteristics affecting the road network system in the high-income country plans is inspiring for this research. In this paper by probing the case study and identifying the most important criteria affecting the comfort of street users, the proposed planning framework is presented in two stages: strategies and alternatives. The alternatives are presented at 3 levels based on the type of intervention, which is weighted by the AHP method. Then, the best and most practical alternative is selected based on the local criteria fitting the conditions of Sabzevar city with the TOPSIS technique. The results indicate that historical contexts, especially in the core of the cities, require conservative approaches; so, as much as possible, without physical destruction, the existing spaces need to distrib-ute among all urban users in the most optimal way for ease of movement. Therefore, in Beyhaq Street, as a historical street in the center of Sabzevar city, by inspiring the methods of global traffic planning, a contextual format of devising has been presented to improve traffic problems.
