Hai Phong highway  In order to gain benefits from road toll collecting and improve convenience for passengers, the equipment will be reviewed and selected for Hanoi - Hai Phong highway  The scope of this project is drawing a directly controlled area of main roads and intersections of Hanoi - Hai Phong Highway that have equipment installed at the scene Designing standards will be applied and referring from which of South Korea and America CONTENT OF THE REASEARCH 2.1 Overview of the traffic management system (TMS) project TMS is a traffic management system used to collect and transmit information via closed circuit television camera (CCTV) and vehicle detection system (VDS), synthesize and analyze traffic situations at Traffic Information Center as well as provide real time traffic information 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 2.2 Details of traffic management system (TMS) Information management of TMS is divided into three steps: collecting, processing and servicing: 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 the information center via the information network of the Hanoi - Hai Phong Highway Project b) Information processing system Information collected is processed for various purposes, including traffic situations and providing information about traffic status Then the processed information is delivered 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 manage traffic Traffic information is distributed by a variety of methods such as VMS, SMS, Internet, TV and publishing in traffic radio Figure 2.2: Traffic management System 2.3 Details of traffic management system (TMS) Classification Content Photos CMO -

The controller should display the necessary signals on the display panel by processing signals sent from the CMO even under bad conditions at the scene - CMO should have the ability to respond to power cut, door (open / close), inside temperature, fan operation, voltage, etc if requested Also, if necessary, it should have interface function to be controlled at the scene - Supervise communicating problems (check the transmission of CRC frame; check the overtime contact, etc.) Cabin box Category Function - Must be a strong structure using beam-H (or panels) as the basic frame to support the weight of the cabin - The outside of the frame should be covered in 1.6T steel plate and light black color after rust-proof coating - Install the output for post-installation maintenance unit Cabin box - Make sure there’s enough space in the cabin for post-installation maintenance - There should be a lock system to prevent external objects - Install ventilation and fans to maintain the temperature (inside the cabin) under 50 ℃ - Waterproof structure should be used to prevent rainwater - Effects from the vibrancy of the vehicles should be eliminated Contact methods VMS contacts CMO in real time using the communication devices that supports two-way communication The data is transmitted to the CMO via optical transmission equipment Use a private network for communication between VMS device-installed scenes and the central operator (CMO) 2.5.9 Weight in Motion System The purpose of the Weight in Motion system is to help the investors or operators of the highways detect and regulate the overloaded vehicles To protect the highway from being damaged by overloaded vehicles, it is necessary to install equipment at toll booths and measure the weight of all vehicles on the highway Figure 2.5.9 Weight in motion system 2.6 Functions of the TMS software 2.6.1 Database management software  Plan the database to manage data efficiently and stably  Backup and recover data, store and manage backup data 2.6.2 Management software of automated license plate detection device  Manage video data recorded from lanes efficiently  Functions of the software -
