Different stakeholders of transportation system are often found concerned with different aspects of it. For instance,
- The traveller or commuter thinks about what will be the travel time on a particular route? Whether he/she will be able to reach the destination in time?
- The transportation manager thinks about how the system performed yesterday? which locations are the worst performers?
- The traffic engineer thinks about the locations of congestion hotspots and the peak hours for various routes.
- The planners and researchers think about what will be the travel demand in future and how they can address it.
Based on their concerns, they have different expectations from the "Intelligent Transportation System". I am looking for these expectations from different perspectives especially for developing countries like India.
Intelligent Transport Systems cover technologies based on the use and application of information and communication technologies in the transport sector, which are used to provide services for people, vehicles and infrastructure on the way to a Smart City.
The basic concern is to guarantee, secure and increase the mobility of road users. Mobility must be seen as a basic human need on the one hand, and as a possibility linked to infrastructure to pursue daily activities at different locations on the other. Mobility is therefore both a characteristic of the quality of life of individuals and a prerequisite for the economic success of society as a whole.
Intelligent transport systems make significant contributions to maintaining mobility into old age. It can be assumed that the future demand for individual and public transport will continue to increase, precisely because of the demographic development in industrial nations. To be able to meet this higher demand, the existing traffic infrastructure must be operated efficiently in terms of energy efficiency and environmental compatibility. A major contribution to this must be made by the increased use of intelligent transport systems with which an increase in traffic efficiency and traffic safety can be achieved.
Intelligent Transport System to better the society, it depends on the level of development of the country and the technology required.
The key areas that the ITS would address; include among others; identification of congestion spots; blocked lanes; blocked junctions; accidents on the roads; insecure spots etc. These are sometimes termed as bottlenecks that hamper smooth traffic flow.When they are identified by the use of ITS; then solutions may be provided; these solutions would be for example; directing traffic to take other routes so as to avoid the congested spots; blocked junctions.
By addressing bottlenecks early by use of the ITS ; the society would benefit in reduced travel time; reduced wasted man-hours in traffic jams; improved road safety; reduced emissions; reduced stress levels of travelers, etc. Lastly ITS when used holistically would lead to a cleaner and smart environment. The developed counties have achieved this in some of their cities. The case for developing countries the use of ITS is still being implemented or some are planning to implement ITS in the future.
Thank you for providing your valuable insights @Fredrick Lwanga and Olaf Czogalla sir.
Intelligent Transport Systems should be considered as information and communication technologies in the traffic and transport sector, from the aspect of demand for traffic and transport services, supply of traffic and transport services, as well as from the aspect of new systems. The field of demand for traffic and transport services can be improved through the following intelligent traffic and transport systems (ITT): Travel information system (before travel, terminals, in vehicles, multimodal travel), Safety and security systems in traffic and transport, Traffic demand management system (Dynamic control, Dynamic line and Timing determination, Automatic service management, Traffic demand management center, Multimodal travel) Supply of traffic and transport services is enhanced by the construction of the following intelligent systems oriented to the supply: Traffic and transport management (Communication systems, Geographic information systems, Vehicle localization, Passenger counting, Transport management center, Data for decision making, Maintenance - Information system, Carrier software, Emergency transport), Electronic billing services for traffic and transportation (indoor and outdoor systems, payment media). New systems should be introduced in traffic and transport wherever their application improves supply and improve demand. These are the following systems: Intelligent Vehicles, Mass Transmission Management, Background Based Communications.
By optimizing the application of these systems, the basic functions of the network of roads (Opening, Connecting and Stay) are improving and the city becomes Smart Sity.
It is very important that in the planning and realization of the construction of certain intelligent systems, the order and the interconnectedness of these systems are taken into account. The absence of a control center that connects other subsystems can make the whole system inefficient. It is also important for employees to be lifelong focused on planning, design, operation and maintenance. This avoids a situation in which only the procurement of the system is important, and after the acquisition, the system is difficult to function or reject as unjustified.
Intelligent Transportation Systems (ITS) are advanced applications or services that combine communication, information and positioning technologies with transportation engineering.
They favor:
The quality of service and comfort for the user, safety, better coordination for traffic management. They facilitate the transfer to means of transport that are more economical in terms of time, cost or energy.
ITS can be found in several fields of activity: optimizing the use of transport infrastructure, improving safety (including road safety), and developing services. The use of ITS is also part of a context of sustainable development: these new systems contribute to the control of mobility by favoring other modes that are more respectful of the environment.
ITS intervene in a global context of traffic congestion on the one hand and development of new information technologies on the other hand, particularly in the fields of simulation, real-time control and networks of information. telecommunication.
The world of research has begun to mobilize around the 1960s to fight against the harmful effects of traffic congestion.
To know the characteristics of the networks, the characteristics of the demand of traffic and the recurring problems, it is essential to have databases. The new technologies based on the ITS make it possible to store large volumes of information.
The challenge today lies in managing these data. For example, creating a common database of data from different operators is useful for analyzing and understanding traffic situations.
ITS are used in public transport to optimize the operation of the network, to improve user comfort and safety. They are grouped under the name (Operating Assistance Systems and Traveler Information)
