چکیده
یکی از عوامل اثرگذار بر تقاطع‌های چراغ‌دار و بدون چراغ، عابران پیاده هستند، لذا شناخت ویژگی­های رفتاری عابر پیاده از اهمیت بالایی برخوردار است و می­تواند به طراحی بهتر امکانات مرتبط با عابران پیاده در توسعه شهر منتهی شود. در این مقاله با تصویربرداری از دو تقاطع چراغ‌دار و دو تقاطع بدون چراغ در شهر رشت به مدت ۱۵ ساعت و آماربرداری از 2423 عابر پیاده، سرعت عبور از عرض عابران پیاده تحت تأثیر وزن و جنسیت آن­ها مورد ارزیابی و تحلیل قرار گرفت. نتایج نشان داد که بیشترین مقادیر سرعت متوسط و سرعت صدک پانزدهم مربوط به آقایان است و این در حالی است که حرکت‌های گروهی در تمام شرایط با سرعت پایین­تری از تقاطع‌ها عبور نمودند و کمترین مقادیر سرعت متوسط و سرعت صدک پانزدهم مربوط به آنان است. تمامی عابران پیاده اعم از آقایان، بانوان و عابران به‌صورت گروهی، در تقاطعات بدون چراغ سریع‌تر از تقاطع چراغ‌دار از عرض خیابان­ها عبور می­کنند. اختلاف سرعت عبور از عرض آقایان، با سطح اطمینان ۹۵ درصد در گروه‌های وزنی لاغر و معمولی به لحاظ آماری معنادار است و این در حالی است که اختلاف سرعت عبور از عرض بانوان، با سطح اطمینان ۹۵ درصد در تمامی گروه‌های وزنی به لحاظ آماری معنادار است.
