چکیده مقاله :

امــروزه فعالیت‌هــای شهری، رفــت و آمــدها و ارتباطات سطح یه شهر به میزان زیادی تغییر کـرده و ایـن تغییـرات بدون توجه به شرایط زیست محیطی و محیط مطلوب انسانی بوده است به گونه ای که مشکلات زیـادی را به ویژه برای انسان‌ها فراهم آورده است. در گذشـته طراحـی مسـیر‌هـا، فضاها و ارتباطات مکانی به گونه ای بوده که اهمیـت ویژه ای به انسان‌ها به عنوان استفاده کنندگان اصـلی در نظر داشته است جنبش پیاده‌راه‌سازی به عنوان یکی از راهبردهای بهبود کیفیت محیط شهری محسوب می‌شود این پژوهش با هدف ارائه الگوی پیاده راه سازی شهری در سطح شهر خرم‌آباد با رویرکردی از نظر هدف کاربردی و از نظر روش شناسی پژوهش توصیفی تحلیل متکی بر مطالعات مدلی و نرم افزار انجام پذیرفته است برای دستیابی به هدف 20 شاخص در 4 دسته از طریق الگوریتم درخت پوشای مینیمم MST در محیط نرم افزار Matlab 2016 استفاده گردیده است و برای فضایی سازی شاخص‌ها از فرآیند تحلیل شبکه (Network Analyst Tools) در محیط نرم افزار ArcGIS استفاده شده است. نتایج نشان می‌دهند که 11758591.7 متر مربع یعنی 29.43 درصد از مساحت بافت شهر خرم‌آباد دارای وضعیت کاملا مناسب، برای احداث پیاده‌راه است همچنین تحلیل فضایی شهر خرم‌آباد نشان می‌دهد که 5 مسیر بهینه برای توسعه پیاده راه سازی این شهر شامل 1: حد فاصل میدان 22 بهمن بلوار ولایت بلوار 60 متری بلوار شرق به سوی کوی انقلاب، 2: خیابان شهید مطهری، چهار راه بانک بلوار شریعتی، خیابان اسد آبادی و میدان مجاهدین اسلام، 3: میدان امام خمینی تا میدان امام حسین(ع) میدان شقایق، 4: خیابان امام و علوی، خیابان کریم خان زند و 5: بلوار بهارستان، بزرگ‌مهر و بلوار ایران زمین است.

چکیده انگلیسی:

Today, urban activities, commuting, and communications at the city level have changed greatly, and these changes have been without regard to environmental conditions and the favorable human environment, so that it has provided many problems, especially for humans. . In the past, the design of roads, spaces and spatial communications has been such that special attention has been paid to humans as the main users. The pedestrian movement is considered as one of the strategies to improve the quality of the urban environment. This research has been carried out with the aim of presenting a model of urban implementation in Khorramabad city with an approach in terms of applied purpose and in terms of methodology, descriptive research based on model and software studies to achieve the goal of 20 indicators in 4 categories. It has been used through the MST Minimal Span Tree Algorithm in Matlab 2016 software environment and the Network Analyst Tools process in ArcGIS software environment has been used to spatialize the indicators. The results show that 11758591.7 square meters, ie 29.43% of the area of ​​Khorramabad city has a completely suitable condition for the construction of sidewalks. Also, the spatial analysis of Khorramabad city shows that 5 optimal routes for the development of sidewalks. This city includes 1: the distance between 22 Bahman Square, Velayat Boulevard, 60 meters from East Boulevard to Enghelab Alley, 2: Shahid Motahari St., Shariati Boulevard, Asadabadi St. and Mojahedin Islam Sq., 3: Imam Khomeini Sq. Hussein (AS) Shaghayegh Square, 4: Imam and Alavi St., Karim Khan Zand St. and 5: Baharestan Blvd.
