For Pedestrian Level of Service (PLOS), there are various methods developed based on different evaluation techniques and philosophy, but, there is no relationship between them nor any formulae to convert rating of one method to another. More importantly, we still do not have any evidence of their success in explaining why and where people prefer walking. In an attempt to analyze the variations and consistency between different PLOS methods, this study used three methods to evaluate 84 walkway locations at the Middle East Technical University (METU) Campus. Three methods employed included PLOS evaluations by Highway Capacity Manual (HCM), Gainesville Method (GM) and Trip Quality Method (TQM). Comparisons were made using a pairwise approach. The results showed that PLOS ratings by HCM were much different than those by the other two methods. Main reason behind this inconsistency was found to be the HCM PLOS definition which was based on flow charactersitics, while the other two methods evaluated the infrastructure and design aspects. Less than perfect ratings of the pedestrian alley by GM and TQM also showed that these methods had limitations coming from their urban planning perspectives valuing more architectural or conflict resolution capacity, which may be not important or valid in a campus design. In the light of the evaluations in this study, PLOS concept has to be improved to reflect different dimensions of walkability together. Also, it should be defined in a way easily customized for specific regions, such as campus evaluations, urban streets, etc.

A new time-domain boundary element formulation for generalized models of viscoelasticity Akay, Ahmet Arda; Gürses, Ercan; Göktepe, Serdar (2023-05-01) The contribution is concerned with the novel algorithmic formulation for generalized models of viscoelasticity under quasi-static conditions within the framework of the boundary element method (BEM). The proposed update algorithm is constructed for a generic rheological model of linear viscoelasticity that can either be straightforwardly simplified to recover the basic Kelvin and Maxwell models or readily furthered towards the generalized models of viscoelasticity through the serial or parallel extensions. ...
Comparison of ASCE/SEI Standard and modal pushover-based ground motion scaling procedures for pre-tensioned concrete bridges Özgenoğlu, Müge; Arıcı, Yalın (2017-01-01) Complex analysis methods such as non-linear time-history analyses (NTHA) are often required for the design of non-standard bridges. The selection of the ground motions for the NTHA is a crucial task as the results of the analyses show a wide variability according to the selected records. In order to predict the demand in accordance with the seismic hazard conditions of the site, the selected motions are usually modified by scaling procedures. Within this context, the performance of two scaling methods, name...
A Multi-criteria decision analysis approach to GIS-based route selection for overhead power transmission lines Dedemen, Yiğit; Karslıoğlu, Mahmut Onur; Department of Geodetic and Geographical Information Technologies (2013) Multi-criteria decision analysis (MCDA) techniques are popular to select the route of linear structures. In this study, Geographical Information Systems (GIS) is employed to assess all the criteria, which are requested to determine the preferable route of power transmission line (PTL). A MCDA model is established on the basis of the Analytic Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE). Because of the complexity of the routing problem, GIS and MCD...
Model updating of nonlinear structures from measured FRFs Canbaloglu, Guvenc; Özgüven, Hasan Nevzat (Elsevier BV, 2016-12-01) There are always certain discrepancies between modal and response data of a structure obtained from its mathematical model and experimentally measured ones. Therefore it is a general practice to update the theoretical model by using experimental measurements in order to have a more accurate model. Most of the model updating methods used in structural dynamics are for linear systems. However, in real life applications most of the structures have nonlinearities, which restrict us applying model updating techn...
A unifying grid approach for solving potential flows applicable to structured and unstructured grid configurations Cete, A. Ruhsen; Yuekselen, M. Adil; Kaynak, Uenver (Elsevier BV, 2008-01-01) In this study, an efficient numerical method is proposed for unifying the structured and unstructured grid approaches for solving the potential flows. The new method, named as the "alternating cell directions implicit - ACDI", solves for the structured and unstructured grid configurations equally well. The new method in effect applies a line implicit method similar to the Line Gauss Seidel scheme for complex unstructured grids including mixed type quadrilateral and triangle cells. To this end, designated al...
