Sustainable transportation aims encouragement of non-motorized (pedestrian and bicyclist) and shared-ride transportation modes instead of car-dependent travels. This is important for university campuses, as they have better chance to implement such policies in a rather controlled traffic network, and can set an example to other communities. Most of sustainable campus transportation programs boil down to reduction of car-based emission cost of campus mobility, which is always the first step in developing more sustainable transportation policies. Middle East Technical University (METU), Ankara has a large campus area and a population over 30,000 people. To develop sustainable campus transportation policies, it was important to quantify the current levels of mobility and vehicle emissions within the campus, which was the main motivation behind this study. This required determination of i) campus origin-destination matrix, ii) in-campus vehicle-km-travelled (vehicle-km), and iii) carbon emissions. Travel data obtained from different sources, including the gate entry with RFID systems enabled analysis of different user groups, such as academic and administrative personnel and students, separately. The traffic simulations were prepared in PTV VISUM, which provided both speed and vehicle-km values for road segments, and could represent multi-user group demand matrices in a single traffic assignment. Based on the base case mobility and emission values, more sustainable campus transportation policies were simulated in PTV VISUM, and assessed in terms of carbon emission impacts. Discouraging of private car usage by students seemed the first and simplest action.

Şenbil, Metin; Yetişkul Şenbil, Emine; Özuysal, Mustafa (2022-01-01)
Accessibility can be defined as easiness in reaching locations by means of transportation and its infrastructure. It is a physical characteristic revealing (relative) attractiveness of a location. Mobility, on the other hand, is a real-life counterpart of potentials produced by accessibility, with spatial behavioural dimensions considering socio-economic, cultural and demographic characteristics. For example, different aspects of trip-making behaviour is an important aspect of mobility. This study deals wit...

To achieve a sustainable traffic management and sustainable transportation planning in urban areas one of the tools that can be used effectively is Geographic Information Systems. In Turkey Transportation Department under Civil Engineering deals with roads and railways which are open to public such as inner city and outer city traffic arrangements with General Directorate of Security. This paper aims to analyze road traffic accident distribution according to the vehicle types involved in the accidents for u...
Exploring critical success factors for blockchain-based intelligent transportation systems
Çaldağ, Murat Tahir; Gökalp, Ebru (2020-01-01)
Utilization of Intelligent Transportation Systems (ITS) provides increasing demands on decreasing traffic congestions, transportation safety, and environmental problems as well as increasing transportation capacity. Over the past few years, one of the most disruptive and transformational technologies, blockchain technology, has emerged. As a result of offering more security, privacy, traceability, transparency, and decentralized authority, the utilization of blockchain technology in ITS have increased drast...
Public transport improvement policies : assessment of the role of route and fare integration, modal reorganization with special emphasis to İzmir case
Öncü, Mevlüde Ayça; Babalık, Ela; Department of Urban Policy Planning and Local Governments (2007)
Public transport improvement and new public transport management approaches are accepted as the most effective tools in order to cope with the urban transportation problem threatening sustainable urban life and efficient functioning of urban areas. The need for new solutions to replace, or support, costly new capacities created two new concepts at the two ends of the transportation phenomenon; Travel Demand Management (TDM) on the demand side and Transportation System Management (TSM) at the supply side. Th...
Analyzing safety toward a walkable campus: a case-study of Middle East Technical University (METU)
Rashidi, Soghra; Akkar Ercan, Z. Müge.; Urban Design in City and Regional Planning Department (2019)
Walkable places are one of the most common features of sustainable, vibrant and healthy cities in the world. Building walkable cities can be a strategy to mitigate some of the problems related to sustainability. As a part of a city, university campus sites provide learning, working and sometimes living environments where mobility and pedestrian walkability should be considered as important design factors to achieve sustainable urban environments. Walkable environments should be the spaces which provide camp...
