This study investigates the relevance of dynamic traffic assignment models under uncertainty. In the last years researchers have dealt with advanced traffic control systems since road provision is not regarded as a proper solution to relieve congestion. Dynamic assignment which is an essential component of investment planning is regarded as a new research area in the field of urban transportation. In this study the performance of dynamic traffic assignment method, which incorporates time dependent flow, is compared with that of static model. Research outcomes showed that dynamic assignment method provides more reliable outcomes in predicting traffic flow; therefore its solution algorithm is integrated to conventional four staged model. Literature survey showed that researches have hot provided an appropriate framework for transforming networks. This study investigates travel demand variations in a dynamic city and discuses possible strategies to respond dynamic and uncertain properties of individuals̕ travel behavior. Research findings showed that both external and internal uncertainties have significant influences on reliability of the model. Recommended procedure aims reducing uncertainty in order to improve reliability of model. Finally, the relevancy of the problem and the applicability of recently developed methods are discussed in Ankara case.

Traffic Network Control From Temporal Logic Specifications
Coogan, Samuel; Aydın Göl, Ebru; Arcak, Murat; Belta, Calin (2016-06-01)
We propose a framework for generating a signal control policy for a traffic network of signalized intersections to accomplish control objectives expressible using linear temporal logic. By applying techniques from model checking and formal methods, we obtain a correct-by-construction controller that is guaranteed to satisfy complex specifications. To apply these tools, we identify and exploit structural properties particular to traffic networks that allow for efficient computation of a finite-state abstract...
Trip-focused organizational safety climate: Investigating the relationships with errors, violations and positive driver behaviours in professional driving
Öz, Bahar; Özkan, Türker (Elsevier BV, 2014-09-01)
The aim of this study was to investigate the relationship between trip-focused organizational safety climate, and driver behaviours, (i.e., errors, violations and positive driver behaviours) in professional driving. A total of 219 male professional drivers participated in the study. The participants were asked to fill out the Driver Behaviour Questionnaire together with the Positive Driver Behaviours Scale; Trip-focused Organizational Safety Climate Scale (TOSCS); and a demographic information form. Factor ...
Politics of urban transportation local, national and international dynamics case of Ankara and Eskişehir road corridor
Öncü Yıldız, Mevlüde Ayça; Babalık, Ela; Department of Urban Policy Planning and Local Governments (2015)
This study aims to identify the factors that influence the development of Ankara’s urban transport system and to assess the effects of influencing groups and actors (referred to as assemblages in this study) on urban and transportation development of Eskişehir Road Corridor in relation with economic development, political decisions, institutional and legal frameworks. The thesis adopts a multi-level analysis method for researching influencing developments and assemblage relationships shaping urban transport...
Traffic climate and driver behaviors: Explicit and implicit measures
Uzumcuoglu, Yeom; Özkan, Türker (Elsevier BV, 2019-04-01)
Traffic climate is about the road users' attitudes towards traffic context and it is assumed that perceived traffic climate might influence drivers' behaviors. In the literature, traffic climate was measured only by using self-report questionnaires. People might give biased responses to self-report measures due to social desirability. The aim of the current study was to develop the first implicit measure for traffic climate. In addition, both implicit and explicit attitudes towards traffic climate and their...
Lifestyle traits as predictors of driving behaviour in urban areas of Greece
Chliaoutakis, JE; Koukouli, S; Lajunen, T; Tzamalouka, G (Elsevier BV, 2005-11-01)
The aim of this study was to examine possible links between different lifestyle patterns and aberrant driver's behaviour. Personal interviews were conducted in a representative sample of 324 adults (18-65), all residents of Crete. Aberrant driver's behaviour was assessed by the 'driver behaviour questionnaire' (DBQ). Also to measure different dimensions of lifestyle, first, a 26-items questionnaire was used, and second, three questions measuring 'driving without destination', related in previous findings wi...
