Abstract: PURPOSE: An electronic display device for a road with a light shielding film is provided to prevent the decrease of the luminance ratio of an electronic display device and to prevent the visibility decrease of the electronic display device by covering the front side of the electronic display device with a sunlight shielding film during the day and by removing the sunlight shielding film during the night. CONSTITUTION: An electronic display device for a road with a light shielding film comprises a body(10), an information indicating portion and a light shielding portion(30). The body is located by a support at a given height and ensures the visibility of a driver. The information indicating portion is installed in the body and displays images on traffic related information to the outside. The light shielding portion is installed in the body. The light shielding portion is driven by a driving unit and selectively covers the front side of the information indicating portion.

Abstract: PURPOSE: A system and a method for providing real time variable velocity information using a Bluetooth are provided to generate reliable section traveling velocity information by applying an error data filtering algorithm. CONSTITUTION: A first Bluetooth sensor(110) is installed in an entry of a construction section or a bottleneck section of a road. The Bluetooth sensor detects vehicle identification information and scanning time from a passing vehicle(210). A second Bluetooth(120) is installed in an exit of the construction section or the bottleneck section of the road. The second Bluetooth sensor detects the vehicle identification information and the scanning time from the passing vehicle. A portable variable message sign(PVMS)(130) displays to a rear vehicle(220) by receiving variable velocity information from the second Bluetooth sensor. [Reference numerals] (110) First Bluetooth sensor; (120) Second Bluetooth sensor; (130) Portable variable message sign(PVMS); (210) Passing vehicle having Bluetooth; (220) Approaching vehicle; (AA, BB) Wireless communication; (CC, DD) MAC address; (EE) VSL display; (FF) Moving; (GG) Traveling direction; (HH) Construction section/bottleneck section; (II) Variable speed limited section

Abstract translation: 目的：提供使用蓝牙提供实时可变速度信息的系统和方法，以通过应用错误数据过滤算法来生成可靠的分段行进速度信息。 规定：第一个蓝牙传感器（110）安装在道路的建筑部分或瓶颈部分的入口处。 蓝牙传感器从通过的车辆（210）检测车辆识别信息和扫描时间。 第二个蓝牙（120）安装在建筑部分的出口或道路的瓶颈部分。 第二蓝牙传感器检测车辆识别信息和从过去的车辆的扫描时间。 通过从第二蓝牙传感器接收可变速度信息，便携式可变消息符号（PVMS）（130）显示给后部车辆（220）。 （附图标记）（110）第一蓝牙传感器; （120）第二蓝牙传感器; （130）便携式可变消息符号（PVMS）; （210）具有蓝牙的通过车辆; （220）接近车辆; （AA，BB）无线通讯; （CC，DD）MAC地址; （EE）VSL显示; （FF）移动; （GG）旅行方向; （HH）施工科/瓶颈部分; （二）变速限制段
