Traffic Touch Screen Monitor

Traffic touch screen monitor is the core interactive terminal of intelligent transportation system. It has evolved from a single ticketing device to an intelligent infrastructure integrating passenger information service, self-service ticketing, vehicle dispatching and outdoor navigation, and is the key hardware entrance for public transport to achieve digital transformation, improve operational efficiency and passenger experience.

🖥️  Core functions: from "information publishing" to "intelligent service"

As a direct window for passengers to interact with the traffic operation system, it undertakes the following key functions:

Passenger information service and intelligent navigation: real-time display of arrival forecast, line operation, vehicle location, transfer query and other information. The touch screen of the intelligent bus station in Suzhou goes a step further and is equipped with an intelligent interactive system connected to the DeepSeek big model. Passengers can talk with the AI digital person "Su Xiaomei" through voice to get advice on route planning, surrounding catering attractions, etc. The smart window of Chongqing rail transit adopts transparent OLED display and nano capacitive touch film technology, so that passengers can view the route, arrival information and surrounding food on the window.

Self service ticketing and inquiry service: It supports passengers to purchase tickets, recharge, ticket card inquiry and exception handling by themselves. The intelligent self-service ticketing terminal supports two-dimensional code payment, voice and touch screen operation, which can replace the traditional automatic inquiry machine. Internet ticket vending machine (iTVM) provides non cash ticket selling, intelligent customer service and voice inquiry, and has a Chinese and English interface.

On board dispatching and driver operation: On the bus, the on-board touch dispatching screen is the driver's core operating terminal. It integrates functions such as vehicle information display, SMS sending and receiving, IP calling, dispatching management, parameter query, reversing display and driver swiping card. This kind of equipment usually adopts the double operation mode of keys and touch to ensure that the driver can complete the operation safely and efficiently during driving.

Operation data visualization and emergency linkage: in the control center, touch screen monitor is used to monitor vehicle status and line operation in real time. Operators can monitor vehicle operations and adjust routes and departure intervals accordingly by displaying real-time information (such as bus arrival time and vehicle status). The system can also push an emergency notice in time to help passengers quickly adjust their travel.

🛠️  Technical characteristics and key indicators

In order to meet the strict requirements of high flow, outdoor exposure and 7 × 24 hours non-stop operation in the traffic scene, the traffic touch screen monitor has a special hardware design.

1. Environmental adaptability and protection

Protection level: outdoor or semi outdoor equipment usually requires the front panel to reach IP65 (dust and water spray prevention) or IP66 to resist dust, moisture and ultraviolet rays.

Wide temperature operation: it needs to support a wide temperature range of -20 ℃ to 60 ℃, and some special models of rail transit even support -25 ℃ to 55 ℃, so as to ensure stable operation in hot and cold weather.

Impact resistance and vandalism: IK08 anti-collision grade is required to resist accidental collision and man-made damage that may occur in public places.

Readability in the sun: outdoor screen brightness needs to reach 1000 to 1500 nits, high-end vehicle mounted display can reach 4500 cd/m ², supplemented by AG anti glare and AR anti reflection processing, to ensure clear picture under strong light.

Electromagnetic compatibility: ESD anti-static and EMI anti electromagnetic interference design is required to ensure stable operation in complex traffic electromagnetic environment.

2. Special certification of rail transit

Rail transit on-board equipment needs to pass more stringent industry standard certification, which is the core threshold for entering this field:

EN 50155: Standards for Rail Transit Onboard Electronic Equipment, covering requirements for wide temperature, vibration, impact, etc.

EN 45545-2: Fire safety standard for rail transit vehicles.

Some rail transit HMIs also support MVB (multi-functional vehicle bus) interface for deep integration with train control system.

3. Size, touch and interface

Size selection: 7 to 10.1 inches for on-board dispatching screen; The passenger information terminal is usually 19 to 32 inches; The large screen of the bus stop can reach 55 to 75 inches.

Touch technology: Projective capacitive (PCAP) touch screen is the mainstream, which supports multi-point touch, and needs to support gloved operation and readability in the sun to adapt to the use scenarios of drivers and outdoor passengers.

Interface configuration: It needs to have a variety of interfaces, including USB, HDMI, VGA, RJ45, RS232, etc., for connecting sensors, cameras, printers, ticket readers and writers and other peripherals.

Payment integration: self-service ticketing terminals need to integrate NFC, MSR (magnetic stripe reader), RFID, scanning code payment and other payment technologies
