Evaluating wider impacts of transport using an integrated urban CGE model

Yılmaz, Özhan
This study follows the literature that utilizes a more hybrid approach to grasp the heterogeneity among different agents in an urban context. Such an integrated approach can handle impacts of transport policies comprehensively, while simultaneously capturing the behavioural heterogeneity of different agents. This is achieved by adding model components capturing key theoretical elements of discrete choice theory into an applied general equilibrium model. “Full integration”, where all blocks of models run simultaneously to find an equilibrium, makes distinct this study from the similar ones. After testing the proposed model using a pseudo data set, and different household categorisation settings and scenarios, I applied it to evaluate effects of London’s planned Crossrail 2 project, which aims at connecting North and South London rail systems. I used London Travel Demand Survey (LTDS) micro-data in the analysis. Model results show that rental price would increase significantly in certain boroughs (Waltham Forest, Merton, Barnet, Enfield and Kingston upon Thames) where the project improves the public transport accessibility. The total increase in public transport ridership by 32,280 leads to a 6 per cent increase the public transport use in commuting. Model results show that number of households in boroughs, in which public transport accessibility is improved due to the Crossrail 2 project, increases while central boroughs lose a considerable number of households to these boroughs. Leaving aside the innovation it offers, the key outcome of this study is the required accumulation of knowledge and motivation for future studies in fully-integrated urban CGE models. Findings of this research and newly introduced approaches and methods can be used to develop a more comprehensive model employing all the capabilities of CGE and urban transport modelling.


Evaluating the effects of a transport infrastructure improvement on heterogenous household groups using an urban cge model
Topuz, Yunus Bulut; Voyvoda, Ebru; Department of Economics (2019)
This study evaluates the economic effects of urban transportation policies on different household groups utilizing a CGE model integrated with a discrete choice model and a traffic model. The London Travel Demand Survey (2004) data is utilized basically in this study and two alternative transport policies which are an improvement in public transportation infrastructure and a price increase in the congestion charge are examined. Households are heterogenized according to their living locations, working places...
Modelling Energy Consumption of the Republic of Serbia using Linear Regression and Artificial Neural Network Technique
Protic, Milan; Fathurrahman, Fahman; Raos, Miomir (Mechanical Engineering Faculty in Slavonski Brod, 2019-02-01)
The objectives of the study are twofold. First, we aim to examine the most influential socio-economic indicators to explain energy consumption in Republic of Serbia. The second objective is to develop models that are able to predict the future energy consumption in the Republic of Serbia. This could be the first important step towards proper energy management in the country. Several potential socio-economic indicators are selected to be the independent variables. Regression analysis is conducted to select t...
Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT)
Kalay, Isil; Yigit, Deniz; GÜLLÜ, Mustafa; DEPCİ, TOLGA; Toppare, Levent Kamil; Hacioglu, Serife O. (Elsevier BV, 2020-09-01)
In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a carbazole comprising monomer; 9-(2-(4-(Phenyldiazenyl) phenoxy) ethyl)-3,6-di(thiophen-2-yl)-9H-carbazole (M1). Carbazole containing monomer (M1) and EDOT were combined with two different comonomer feed ratios, 1: 3 and 1: 5 respectively in order to investigate the effect of increasing EDOT amo...
Analyzing the effects of the personality traits on the success of online collaborative groups
Kucukozer-Cavdar, Seyma; Taşkaya Temizel, Tuğba (Elsevier BV; 2016-06-23)
The purpose of this study is to analyze how efficient online study groups can be formed among students based on their personality traits. A survey consisting of Ten Item Personality Inventory (TIPI) was conducted among the undergraduate students in a well-known university. Eighty-two students who did not know each other were assigned to 35 small online groups based on their personality characteristics. The group members were then asked to study collaboratively on a task by communicating via the university's...
Determination of Rainfall – Runoff Relationship in Yenicegoruce Basin with HEC-HMS Hydrologic Model
The goal of this study is to model rainfall-runoff process using HEC-HMS developed by U.S. Army Corps of Engineers for the 10,508 km2 catchment that has E01A012-Yenicegörüce stream gage at its outlet which is located just at the upstream of the point where Meric and Ergene Rivers meet. This study is conducted as a part of 115Y064 numbered “Development of a geographical information systems based decision-making tool for water quality management of Ergene watershed using pollutant fingerprints” project funded...
