براي بدست آوردن نيازهاي سيستم حمل و نقل در يك كشور تصميم گيري ها بايستي بر اساس اطلاعات در دسترس آسان و به روز و قابل اطمينان باشد. امروزه سيستم اطلاعات جغرافيايي (GIS) بصورت يك تكنولوژي با پتانسل قابل توجه براي دستيابي به اهداف لازم براي بسياري از كاربردهاي حمل و نقل قديمي به وجود آمده است. كاربرد GIS در زمينه مهندسي حمل و نقل بعلت ماهيت توزيع شده از داده هاي مربوط به حمل ونقل و نياز به انواع تحليل ها در سطح شبكه و تحليل آماري امروز بيش از بيش اهميت يافته است. اولين تلاش در استفاده از سيستمهاي اطلاعات جغرافيايي در حمل و نقل در آمريكا در سال 1990 آغاز شد و در سالهاي بعد در كشور انگليس و اخيراً در كشور هند مورد استفاده قرار گرفته است كه متاسفانه در كشورمان ايران چندان مورد توجه قرار نگرفته است.
با توجه به گسترش روز افزون استفاده از سيستم هاي حمل و نقل شهري و ازدياد تقاضاي سفرها و حجم بالاي تردد هاي صورت پذيرفته و نياز به تأمين امكانات اوليه و زير بنايي اين سيستم حمل و نقل و نياز مبرم به ارائه يك مديريت توانمند جهت عدم مواجه يا كاهش معظلات حمل و نقلي استفاده از سيستم اطلاعات جغرافيايي جهت تلفيق اطلاعات لازم در حوزه حمل و نقل و GIS بيش از پيش ضروري مي نمايد. از اين رو در اين بخش عمده ترين پروژه ها و نيز معظلات حمل و نقلي كه مي توان از سيستم GISبه نحوه مطلوبي مديريت گردد به شرح زير ارائه مي گردد :
• مديريت بر عمران معابر شهري
• مديريت بر ساخت پايانه ها و پاركينگهاي طبقاتي شهري
• طراحي سيستم شوراي نامگذاري معابر شهري
• مديريت بر توسعه پمپ بنزين و پمپ گاز
• مديريت بر چراغهاي راهنمايي و سيستم مونيتورينگ تقاطهاي شهري
• مديريت بر اجراي خط كشي طولي معابر و سرعت گيرها و نصب تابلوهاي راهنماي و رانندگي
• مديريت بر ايستگاه ها و مسير هاي اتوبوسراني شهري
• مديريت تاكسراني شهري
• مديريت و سازماندهي سيستم تاكسي تلفني هاي شهري
• مديريت راه ها و پياده رو هاي برون شهري
تأثير تكنولوژي GISدر توسعه سيستم اطلاعات حمل و نقل و مديريت زير ساخت راه ها بسيار عميق مي باشد به نحوي كه اگر حداكثر استفاده از تكنولوژي GISدر بحث حمل و نقل به كار گرفته شود مي تواند روند تصميم گيريها را در مهندسي حمل و نقل و ترابري شهري متحول كند.
