Full-text available
A study of pedestrians crossing behavior is conducted at an uncontrolled mid-block crosswalk in Istanbul, Turkey, to model the pedestrians waiting time, related to their behavior for making the crossing decision. This article focused on the issues encountered in the modeling of the operational behavior of pedestrians. The discrete choice framework...
Article
Full-text available
Although the four-step model is the most common method in transportation demand modelling, it is exposed to a considerable criticism in terms of representing the actual choice behaviours of travellers. For example, the four steps are presented in a fixed sequence and independently from each other. Such assumption may be correct in case of obligator...
Article
Full-text available
Despite traditional four-step model is the most prominent model in majority of travel demand analysis, it does not represent the potential correlations within different travel dimensions. As a result, some researches have suggested the use of choice modelling instead. However, most of them have represented travel dimensions individually rather than...

Full-text available
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 the crosswalks were located on three-lane streets while the other one was on a two-lane street. By using two-hour video record...

This paper aims to introduce a new modelling approach that represents departure time, destination and travel mode choice under a unified framework. Through it, it is possible to overcome shortages of the traditional 4-step model associated with the lack of introducing actual travellers' behaviours. This objective can be achieved through adopting di...
Conference Paper
This paper aims to examine the inter-relationship (dependency) between departure time, destination and transportation mode alternatives of discretionary trips under a single unifying framework. This can be achieved through developing a number of two-level Nested Logit models that can incorporate different correlation structures. The proposed models...
Conference Paper
Traffic congestion is one of the most significant problems that face most cities around world. That leads governments to dedicate huge investments on policies that aim to mitigate and manage it. One of these policies is increasing travel cost at specific times within specific regions to force people avoid using private vehicle or completely avert t...
Conference Paper
Urban rail systems are considered as safe, fast and sustainable systems because traffic and pedestrian intersection areas are less than those of rubber-tired public transportation systems. Although metro and light rail systems with high capacity and completely independent lines in the city are the safest and reliable systems because they do not int...

Importance given to transportation investments increase in developed countries day by day. Therefore, effective planning plays a significant role either in new transportation investments or in improving present transportation system. To make well-conceived planning for urban transportation, mode choices (automobile, taxi or public transport) and tr...
Article
In many cities, different developments in economic, social, and physical environment significantly influence the transportation demand. When the demand could not be matched by capacity expansions, sustainability is tried to be attained via various demand management strategies. In this study, optimization of the commuting trips for demand management...

Kent içi toplu taşıma sisteminin önemli parçasını oluşturan otobüs sisteminde, genelde iki tip durak ile yolcuların iniş/binişleri sağlanmaktadır. Bunlar, otobüslerin yol içinde ve yol dışında durdukları durak tipleridir. Otobüsler yol içinde, sağ şeridin sağında durduklarında mevcut trafik akımını etkilemektedirler. Bu etkilenmeyi azaltmak için yo...

Traffic congestion is one of the major problems of large metropolitan cities. Apart from recurrent congestion that is a regular disturbance for inhabitants of these cities; irregular congestion borne by issues such as traffic incidents or special events is another aspect in this context. The focal point of this paper is the special events which are...
