ITS systems are gaining a great deal of attention, research and investment in the world as well as in Vietnam. We are gradually building “Smart government”, “Smart City”. And “Smart Transportation” will be an essential part of the development.
In fact, currently, ITS services are mostly on the highway in Vietnam. The regulations related ITS systems also primarily serve the implementation of ITS systems on a highway. Meanwhile, it seems that there is no attention and research on how to apply ITS systems to urban centers.
In Vietnam, FIS FTS is a pioneer in researching and applying ITS for an urban area, especially “smart bus system ” which is implemented in Ho Chi Minh City since 2014. Its functions are supervising and operating online bus (monitor location of vehicles, time of drivers, schedule, warn automatically when they infringes: wrong routes, open door while moving, stop too long on the route,… ) ; provides online information (Electronic table clock show which cars and what time they arrive on mobile devices, online maps, … ).
The smart bus system has been deployed to Ho Chi Minh City Management and Operation Center for Public Transport – HCM City Department of Transportation. It connects ~ 3,000 public buses attached to monitoring devices which are supplied by 12 Transport Companies; 4000 bus stops; ~ 17 000 trips/day; 12 million events/day; providing online services for people at http://cms.ebms.vn/

“Investing in electronic ticketing in public transport by bus in Ho Chi Minh City under Public Private Partnership (PPP) form” is built by FIS FTS to meet the entire bus network. It is ready for expansion and integration with passenger transportation systems such as buses rapid transit (BRT ), Mass Rapid Transport (MRT), urban railway system, … are about to put into operation in Ho Chi Minh City.

Besides smart bus system, FIS FTS is researching and analyzing online data to monitor journey, forecast traffic conditions and calculate travel time on the digital maps.

Add online data from monitoring devices, solutions to collect traffic parameters such as traffic density, vehicle density, the speed of vehicles, … FIS FTS research using image processing technology photos ( Video Image Processing ) and deployed into ~ 500 cameras in many categories with a lot of technology. Big investors and organizations in HCM city such as Police, Department of Transport, VOV traffic provide information about traffic at http://thongtingiaothong.vn

The most important thing for ITS to deploy is to put it into the traffic management concept. The ITS system is understood as an essential tool for the implementation of strategies and solutions for traffic management, and to use of ITS applications which impact on the organization with the aim of balancing traffic between traffic demand and capacity of the infrastructure.
An intelligent transport system for an urban must ensure services of public transport operations and private transport. Therefore, it requires synchronized deployment and connection of each ITS systems in 2 criteria. The first requirement is the integration of components to ensure interoperability to connect applications as well as ensure technical integration to ensure interoperability to connect equipment and technology, including sharing data among peripherals, transferring files, creating communication channels… to collect and process online traffic data.
With regard to the ITS system for urban areas, where there is a series of smart vehicle, data requires immediacy so that it can help users timely to control traffic, to avoid congestion at each intersection, and to warn dangers. Therefore, this system needs to be good at distributing data so that it can mitigate transmission capacity on the network by only distributing data which is related to changes of traffic parameters and still ensure accuracy, updated information and adapt to millions of terminals in an ITS system. The basic criteria can be solved thanks to some fundamental characteristics and High-level requirements of an IoT.
The fundamental characteristics of the IoT are as follows:
Interconnectivity: With regard to the IoT, anything can be interconnected with the global information and communication infrastructure.
Things-related services: The IoT is capable of providing thing-related services within the constraints of things, such as privacy protection and semantic consistency between physical things and their associated virtual things. In order to provide thing-related services within the constraints of things, both the technologies in physical world and information world will change.
Heterogeneity: The devices in the IoT are heterogeneous as based on different hardware platforms and networks. They can interact with other devices or service platforms through different networks.
Dynamic changes: The state of devices change dynamically, e.g., sleeping and waking up, connected and/or disconnected as well as the context of devices including location and speed. Moreover, the number of devices can change dynamically.
Enormous scale: The number of devices that need to be managed and that communicate with each other will be at least an order of magnitude larger than the devices connected to the current Internet. The ratio of communication triggered by devices as compared to communication triggered by humans will noticeably shift towards device-triggered communication.
The following provide high-level requirements which are relevant for the IoT:
Identification-based connectivity: The IoT needs to support that the connectivity between a thing and the IoT is established based on the thing’s identifier.
Autonomic networking: Autonomic networking (including self-management, self-configuring, self-healing, self-optimizing and self-protecting techniques and/or mechanisms) needs to be supported in the networking control functions of the IoT, in order to adapt to different application domains, different communication environments and large numbers and types of devices.
Autonomic services provisioning: The services need to be able to be provided by capturing, communicating and processing automatically the data of things based on the rules configured by operators or customized by subscribers. Autonomic services may depend on the techniques of automatic data fusion and data mining.
Location-based capabilities: Location-based capabilities need to be supported in the IoT. Something-related communications and services will depend on the location information of things and/or users. It is needed to sense and track the location information automatically. Location-based communications and services may be constrained by laws and regulations, and should comply with security requirements.
Manageability: Manageability needs to be supported in the IoT in order to ensure normal network operations. IoT applications usually work automatically without the participation of people, but their whole operation process should be manageable by the relevant parties.
Internet of Things is an inevitable trend of development and it will be present in all fields of life. Because of its pioneering position in the research and deployment of ITS for urban areas in Vietnam, and experience at integrating large systems, we believe FPT IS can success in researching and putting the IoT advances in ITS for urban centers in Vietnam which have mixed traffic characteristics and it’s difficult to manage. And it is also suitable for other urban areas in the world. Apart from system problems of integrating ITS systems and IoT, we deal with problems of organizational integration and policies to coordinate activities between the ministries (Ministry of Information and Communications, Ministry of Transport, Ministry of Public Security). If this problem is solved, we will be easy to build, manage intelligent transportation system of any city, any area, and even our nation.
