Open data is data that is free of any copyright, that can be freely accessed and used or processed and shared by users without being subject to patents or other control mechanisms, and that can be freely and freely utilized, reused and distributed. For data to be open data, it must be free, easily accessible and easily usable. Open sharing of any data is only possible through an open data platform.
Open Data Platforms are a data management system that makes data accessible and provides tools to make it easier to publish, share, find and use data. Open Data Platforms increase society's access to information, foster innovation, ensure transparency and support decision-making processes.
In the adaptive system, by receiving real-time data from sensors, instead of matching current traffic conditions with existing signal time plans, the best signal time plan is dynamically created instantly. The adaptive system is preferred in cases where demand is high and variable over time, and schedules need to be changed frequently. The distinguishing feature of adaptive systems compared to traffic-actuated systems is that they include optimization-based algorithms that include technologies such as artificial intelligence.
It is a sustainable city where all stakeholders of the city are integrated with the city management, where technological facilities and data are utilized at an advanced level in order to use resources effectively and efficiently in order to improve the quality of life.
Controlling and managing transportation infrastructure and resources with the support of information and communication technologies; These are systems that increase security, reduce travel times and minimize environmental impacts.
National ITS Architecture is a general guide that ensures that stakeholders and systems are compatible, interoperable and do not limit the design options to be added. National ITS Architectures are being developed across the country, covering all ITS needs and services, ensuring ITS interoperability.
Big Data refers to large and complex data sets that come from different sources and cannot be processed by traditional methods due to their volume (amount), speed and diversity. This data is used to understand trends, make predictions and make better decisions using advanced analysis tools and techniques.
Geographic Information Systems (GIS) are used to assist users in space/location-based decision-making processes; all types of spatial and non-spatial information; It is a system consisting of hardware, software, personnel and methods that integratedly perform the functions of collecting, storing, processing, associating, updating, querying, analyzing and presenting.
It is a measurement tool created by compiling and analyzing various indicators determined for any subject in any field. Indices are used to compare the performance and development of items in the selected area.
The number of vehicles passing through a lane, highway or other traffic route during a time period, usually 1 hour.
Simulation is a computational or modeling process that models and imitates the behavior of a real system or event. In transportation systems, simulation is used to analyze real-world situations, predict future outcomes, or test specific scenarios. Simulations reduce costs, manage risks and enable understanding of complex systems.
The Sustainable Urban Mobility Plan (SUMP) aims for a better quality of life, different from the Transportation Master Plans implemented in metropolitan cities in Turkey. It is a strategic plan designed to meet the mobility needs of people and businesses in cities through sustainable mobility modes such as pedestrian, micromobility and public transport.
Sustainability is the process of protecting and managing natural resources and the environment by meeting today's needs while also considering the needs of future generations. Sustainability aims to balance economic, social and environmental factors and promotes long-term prosperity. Sustainability provides a guideline for improving the quality of life of city residents by preserving cities' resources.
In the Full Traffic-Actuated System, there are sensors/cameras for vehicles at all approach arms at the intersection. The right-of-way sequences and times are automatically organized by changing according to the traffic densities at the warned approach arms. Full Traffic-Actuated Systems reduce total delays by providing right of way according to the actual values of traffic densities.
In the Semi-Traffic Actuated system, sensors/cameras are placed to accept the demand from some of the intersection approach arms (mostly secondary roads). A green light signal is constantly given to the flow directions on the road, which is generally a "main road", and there is no change in the light signals of the front groups unless they receive a passage request warning from any of the secondary roads or roads. The main road has the right of way at all times. In case of demand from the secondary road, the flow on the main road is stopped and the right of way is given to the secondary road. The green period can also be extended according to the instant vehicle demand in the stream where the right of way is given.
