[ 1 ] - ارائه مدل نگهداری و بهسازی شبکه راههای اصلی با به کارگیری تحلیل هزینه چرخه عمر -مطالعه موردی استان خراسان جنوبی
به علت گسترش روزافزون راهها و محدودیت در بودجه، مدیریت روسازی همواره مورد توجه محققان بوده است. هدف از این تحقیق در نظر گرفتن تحلیل هزینه چرخه عمر و نرم افزار HDM-4، در راستای تعیین نوع و زمان اجرای بهصرفهترین روشهای نگهداری و بهسازی میباشد. بدین منظور، قطعات همگن اولیه با بررسی عواملی همچون شاخص وضعیت روسازی، شاخص ناهمواری بین المللی و افت و خیز حسگر مرکزی دستگاه FWD، در سطح شبکهای از ...
[ 2 ] - Evaluation of the Effects of Maintenance and Rehabilitation Projects on Road User Costs via HDM-4 Software
Rapid growth in a number of vehicles on roadways accelerates pavement deterioration trends. Pavement inefficiency in carrying the applied load from passing vehicles results in spending significant costs on continues Maintenance and Rehabilitation (M&R) treatments. Lane closure owing to the implementation of M&R operations incurs enormous costs on road users. The research aimed to calculate, and...
[ 3 ] - Identification and Prioritization of Accident-Prone Segments using International Roughness Index
During last decades, owing to the increase in a number of vehicles, the rate of accident occurrence grows significantly. Efforts must be made to provide efficient tools to prioritize segments requiring safety improvement and identify influential factors on accidents. This objective of the research was to determine the safety oriented threshold of International Roughness Index (IRI) to recognize...
[ 4 ] - Prioritization of Suburban Accident Factors Based on Analytical Network Process
The safety management of transportation system leads to decrease in a number of traffic accidents. Identification of the primary reasons in accident incidence is the initial step in controlling the crashes. The source of accidents is divided into 3 groups; namely, human, environment and traffic. Due to the complex nature of traffic accidents, Multi-Criteria Decision-Making (MCDM) methods can be...
