Examination of delay and travel time at highway toll booths using a micro simulation program: example of Northern Marmara Highway Kurnaköy
(2022-04)
The aim of this study is to reveal that barrier toll booths are inefficient in terms of delay and travel time when compared to non-barrier toll booths. In our study, Kurnaköy toll booth, on the Northern Marmara Highway, ...
The investigation of the effect of saturation flow on the average vehicle delay at signalized intersections
(Izmir Democracy University, 2021-12-18)
Saturation flow (s) is one of the most important parameters used for determining of signal timings at signalized intersections. Therefore, this parameter directly affects the various intersection performance criteria such ...
İstanbul çevre yollarında yağmurun serbest akım hızı ve kapasiteye etkisinin irdelenmesi
(TMMOB İnşaat Mühendisşeri Odası, 2019-10-12)
Trafik tıkanıklığının en çok yaşandığı kentimiz, 15 milyondan fazla nüfusuyla şüphesiz İstanbul’dur. İki önemli anayolu (D100 Karayolu ve O2, O3, O4 Otoyolları) üzerinde, zirve saatlerde yapılan yolculukların daha uzun ...
Bariyerli otoyol gişelerinin trafik akımına etkisi: İstanbul Kuzey Marmara Otoyolu örneği
(Osmaniye Korkut Ata Üniversitesi, 2022-07-30)
Bu çalışma bariyerli, nakit ve otomatik ödeme sistemlerinin birlikte kullanıldığı otoyol çıkış gişelerinin trafik akımına olan etkisini ele almaktadır. Gişelerde, nakit ödeme yapan sürücüler tamamen durarak ödemelerini ...
Identification of sensor location and link flow reconstruction using turn ratio and flow sensors in an arterial network
(Taylor and Francis Ltd., 2022-08)
In this article, a quadratic programming problem is considered to identify all link flows in an arterial network when there are unmeasured link flows. A graphical method is provided to determine the minimum number of ...
Direct usage of occupancy data for multiregime speed-flow rate models
(American Society of Civil Engineers (ASCE), 2023-01)
Early macroscopic traffic flow models were based on observations of volume, speed, and density. The invention of traffic sensors has supplied a wealth of data for the development of more accurate macroscopic flow models. ...
Pedestrian crossing behavior at midblock crosswalks
(Elsevier Ltd, 2019-12)
Introduction: This study investigated the pedestrian crossing behavior at midblock crosswalks, in Istanbul. Method: Data were compiled from field studies at four selected crosswalks that were on one-way streets. Three of ...
Investigation of the relationship between upstream and on-ramp flows at downstream capacity level on Istanbul freeway merges
(Muğla Sıtkı Koçman Üniversitesi Fen Bilimleri Enstitüsü, 2021-03-04)
Traffic congestion usually occurs at freeway merges due to the inequality of lane numbers at upstream and downstream. The freeway entry, defined as on-ramp, is the main cause of this irregularity and in order to clarify ...
