[ 1 ] - ارایه روشی برای تشخیص گره‌های ترافیکی در جهت افزایش عملکرد بهینه شبکه ترافیکی

بروز گره­های ترافیکی همواره به‌عنوان یکی از مهمترین معضلات جریان ترافیکی آزادراه­ها شناخته شده­اند. کشف سریع این گره‌های ترافیکی و رفع هر چه سریع­تر آنها همواره به‌عنوان یکی از دغدغه­های مسئولین و محققین در شریانهای اصلی بوده است. بنابراین ارایه مدلی مناسب برای تشخیص این گره­ها و انجام اقدامات لازم جهت تسریع در روان‌سازی جریان ترافیک به‌منظور کاهش اثرات ثانویه از اهمیت خاصی برخوردا...

[ 2 ] - An ANP-based Model for Location of Fixed Speed Cameras

Speeding is a major cause of traffic accidents and is estimated to be the cause of about 40% of fatalities in road accidents. Speed is a major accident risk factor and affects both rate and severity of traffic accidents. This importance has led to universal use of intelligent control systems for maintaining road safety by enforcing speed regulations. In this study, a modeling is carried out by ...

[ 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...
