2.1 Overview of the traffic management system (TMS) project
TMS is a traffic management system used to collect and transmit information via closedcircuit television camera (CCTV) and vehicle detection system (VDS), synthesize andanalyze traffic situations at Traffic Information Center as well as provide real time trafficinformation via variable message sign (VMS), internet, mobile phone and radio
Configuration of TMS information network at Hanoi - Hai Phong Highway
Figure 2.1: Configuration of information network
Trang 42.2 Details of traffic management system (TMS)
Information management of TMS is divided into three steps: collecting, processing andservicing:
a) Information collecting system
Traffic information is collected via vehicle detection system (VDS) and CCTV.Information collected is transmitted to the information processing system at theinformation center via the information network of the Hanoi - Hai Phong HighwayProject
b) Information processing system
Information collected is processed for various purposes, including traffic situationsand providing information about traffic status Then the processed information isdelivered to locations in need of information
c) Information servicing system
Processed information will be transmitted to the monitoring system at the CMO(Central Management Office), particularly the Traffic Information Center to managetraffic Traffic information is distributed by a variety of methods such as VMS, SMS,Internet, TV and publishing in traffic radio

Trang 5CMO - CMO is the core of managing and
operating facilities and processors toprovide safe and easy guidance for drivers
by providing highway users with trafficinformation gathered from collecting /processing / traffic reports analyzing andimprove the function of highway byexploiting highways and traffic equipment.VDS - VDS (vehicle detection system) is
installed on the highway every onekilometer Equipment sensing realistictraffic flow, vehicles speed, road surfaceoccupancy and vehicles to monitor trafficand solve emergencies There are manytypes of VDS such as underground, radar,ultrasonic, magnetic and video recordingtypes
CCTV - Closed - circuit television camera CCTV
identifies traffic jams and accidents.Information video image is transmitted toCMO via fiber optic cables
VMS - VMS (Variable message sign) is installed
at traffic intersections and crossings toprovide highway users with informationabout the status of frontward traffic
LCS - LCS (Lane Control Sign) regulates the
availability of the shoulder of the road tocope with traffic situations
Trang 6RWIS - RWIS (Road Weather Information
System) identifies road surface conditions,wind direction and speed, rainfall on thehighway and transmits data to CMO center
2.4 Research the role of TMS in managing Ha Noi - Hai Phong Highway System
2.4.1 The operating role of TMS
TMS system operation is divided into operation at CMO (Central Management Office) andoperation at regional stations in which traffic management is implemented and emergenciesare controlled The special operating role of TMS system is presented as follows:
CMO
- Manage the overall highways over the country
- Manage the traffic within its range of responsibility
- Carry out traffic projects with regional traffic centers
- Compose traffic information
- Discuss traffic situations with traffic organizations and provideinformation
- Share information with traffic line support group and Disaster MonitoringCenter
Regional
traffic areas
- Manage the overall traffic situation in their range s of responsibility andreport to the CMO
- Compose traffic information
- Manage the information in VMS system
- Discuss traffic situations with main traffic organizations and shareinformation
- Consult the police, close the road if necessary
- Analyze the traffic situation in their range of responsibility and keep theproject handbook
Trang 7- Compose traffic information
- Discuss traffic situations with main traffic organizations and provideinformation
Branch
offices
- Manage traffic in their ranges of responsibility
- Discuss traffic situations with main traffic organizations and provideinformation
- Analyze the traffic situation in their range of responsibility and keep theproject handbook
2.4.2 Utilize and manage the highway system
Highway management includes vehicles control, safety control and the system of operating and managing highways
- Each system supports the operators to make decisions under circumstances
on the highway These systems control the information displayed on theVMS about the current state of congestion, traffic jams and emergencies
Trang 82.5 Research and apply TMS in Hanoi - Hai Phong Highway system
2.5.1 CMO (Central Management Office)
CMO manages traffic effectively by using processed information in appropriate time andspace CMO includes Traffic Monitoring Center, Disaster Monitoring Center, TrafficBroadcasting Studio, Department of Traffic Management and Maintenance and MarketingDepartment Freeway patrols are the police department in collaboration with the TrafficCenter In addition to providing traffic information, the relevant information is synthesizedand then published for the purpose of traffic safety and incidents control, disasters included.Disaster monitoring office is operated 24/24 to handle emergency situations
Figure 2.5.1 CMO StructureReal-time traffic information is distributed to different media network CMO providestraffic information via VMS and SMS and control traffic jams by closing and openingpassing lanes and auxiliary lanes of the toll collecting offices Traffic monitoring center
Trang 9administers a special traffic website The broadcasting studio of this center provides trafficinformation via internet, twisted networks and TV Traffic monitoring center makes effort
to expand the scope of information and diversifies mass media
2.5.2 The traffic website
A special traffic website provides different information online This site provides anelectronic map in real time, CCTV video image, traffic situations on highways and shortestroute search During specific time of traffic management, additional services are provided tocustomers to reduce the inconvenience
Figure 2.5.2 The content of a traffic website
2.5.3 Traffic broadcasting
Traffic broadcasting studio provides information for broadcasting agencies At the time ofbad weather or disaster, special broadcasting programs will be prepared Trafficbroadcasting studio offers various forms including video image and information connectionwith internet portals Customers are encouraged to participate in many events such as UCCvideo programs and awards for road and traffic photography
Trang 10Figure 2.5.3 Traffic broadcasting
2.5.4 SMS Services
The traffic information SMS Service is reports to highway users so they can easily getinformation on highways in text messages By simply entering the start and end point orroute name, and send a message to the traffic center, users can get information about thestatus of the highway and estimated travel time
2.5.5 Traffic report
During special occasion of traffic management such as holidays and weekends, the traffictends to appear complicated Travel time between big cities and traffic status can bepredicted, to help highway users choose the departure time to avoid traffic jams and limitedcommuting time Travel time between the big cities are forecasted in the automated trafficforecast system and bulletins on mass media CMO makes efforts to expand information bydiversifying mass channels
2.5.6 Mobile devices
SMS: Provides information via mobile devices (mobile: Smart phones, tablet PC), somenew social networking services like Twitter, Facebook, YouTube and etc
2.5.7 CCTV television camera system along highways
The role of the system
CCTV monitors observe the traffic situations, increases the convenience for users bychecking the image at the central managing office (CMO) in case of emergency To ensurethe stability, this system should be installed at a distance of 2 kilometers
