Capacity and Delay Estimation for Roundabouts Using Conflict Theory
To estimate the capacity of roundabouts more accurately, the priority rank of each stream is determined through the classification technique given in the Highway Capacity Manual 2010 (HCM2010), which is based on macroscopical analysis of the relationship between entry flow and circulating flow. Then a conflict matrix is established using the additive conflict flow method and by considering the ...

در این بررسی ابتدا به بررسی ماهیت توزیع خسارات پرداخته میشود و از روش نظریه مقادیر نهایی برای بدست آوردن برآورد ارزش در معرض خطر برای خسارات روزانه بیمه مسئولیت شرکت بیمه ایران استفاده میشود. سپس کارایی نظریه مقدار نهایی در برآورد ارزش در معرض خطر با کارایی سایر روشهای واریانس ، کواریانس و روش شبیه سازی تاریخی مورد مقایسه قرار میگیرد. نتایج این بررسی نشان میدهند که توزیع ،garch شناخته شده مدل...
15 صفحه اولModeling and Calibrating Capacity of Large Roundabouts
Roundabout models, available in the literature widely, vary between one method and another. Majority of the models are solely based on circulating fl ow to estimate capacity. The relationship between maximum entry fl ow of large dual and triple lane roundabouts and their geometric and traffi c characteristics is investigated here for saturated fl ow condition using multivariate analysis. The de...
متن کاملSignals and Meters at Roundabouts
With the emergence of the modern roundabout as an effective form of traffic control in the United States, more and more information is needed when situations arise in which additional traffic control is required. The signalization and metering of roundabouts can relieve congestion during peak hours of the day as well as possibly provide safer access for pedestrians and cyclists. Although the si...
متن کاملExploring Prediction Uncertainty in Machine Translation Quality Estimation
Machine Translation Quality Estimation is a notoriously difficult task, which lessens its usefulness in real-world translation environments. Such scenarios can be improved if quality predictions are accompanied by a measure of uncertainty. However, models in this task are traditionally evaluated only in terms of point estimate metrics, which do not take prediction uncertainty into account. We i...
