Abstract
Traffic has a direct impact on local and regional economies, on pollution levels and is also a major source of discomfort and frustration for the public who have to deal with congestion, accidents or detours due to road works or accidents. Congestion in urban areas is a common phenomenon nowadays, as the main arteries of cities become congested during peak hours or when there are additional constraints such as traffic accidents and road works that slow down traffic on road sections. When traffic increases, it is observed that some roads are predisposed to congestion, while others are not. It is evident that both congestion and urban traffic itself are influenced by several factors represented by complex geospatial data and the spatial relationships between them. In this paper were integrated mathematical models, real time traffic data with network analysis and simulation procedures in order to analyze the public transportation in Oradea and the impact on urban traffic. A mathematical model was also adapted to simulate the travel choices of the population of the city and of the surrounding villages. Based on the network analysis, traffic analysis and on the traveling simulation, the elements generating traffic congestion in the inner city can be easily determined. The results of the case study are emphasizing that diminishing the traffic and its effects can be obtained by improving either the public transport density or its accessibility.
Highlights
The process of urbanization is affecting the whole world on an unprecedented scale, leading to constant pressure on urban planners and local governments to deal with the problems it creates: network infrastructure, transportation, risks, disaster prevention and intervention, investment planning and so on.Since urbanization is a continuously developing process, and one of its main pillars is a fast-developing transportation network, planners are becoming more interested in balancing sustainable development with sustainable transportation
The future of cities depends on the capacity for innovation and the ability to harness the socio-economic and cultural resources of all the actors involved in the development of urban society
Public transportation and traffic control can be used as an instrument of urban management towards a sustainable urban development
Summary
The process of urbanization is affecting the whole world on an unprecedented scale, leading to constant pressure on urban planners and local governments to deal with the problems it creates: network infrastructure, transportation, risks, disaster prevention and intervention, investment planning and so on.Since urbanization is a continuously developing process, and one of its main pillars is a fast-developing transportation network, planners are becoming more interested in balancing sustainable development with sustainable transportation. A certain element to be taken into consideration while defining sustainable traffic systems is where the system will be implemented: urban/rural areas, large/small communities, traffic hubs, type and location of different functional areas within the community (residential, cultural, educational, business and so on), local traditions, developed/undeveloped communities [4]
