Description

Notification and formation method of real-time traffic road conditions

The invention relates to intelligent transportation, and particularly to a method for reporting and forming real-time traffic conditions.

Taiwan is located in the subtropical zone and is located on the Pacific Rim earthquake belt. Therefore, it is likely to suffer from natural disasters such as typhoons, heavy rains and earthquakes every year. In addition, Taiwan's geology is fragile. When facing natural disasters such as earthquakes, typhoons and heavy rains, earth and rocks are easy The landslide is loosened, so I often hear the main external traffic roads of Alishan in Chiayi County or Suhua Highway in Hualien County. Due to the danger of rockfall or slope landslides, road closure measures will be taken from time to time, causing many tourists to suffer from lack of information or opacity Stuck in the middle of the road, if you can provide timely, accurate and easy-to-query traffic information, you can save the time and energy consumption of pedestrians.

At present, the main sources of road traffic information in Taiwan are police and real-time traffic conditions (http://rtr.pbs.gov.tw/pbsmgt/RoadAll.html) and provincial highway real-time traffic information network (http://168.thb.gov. tw / thb / navigate.do), but its main operation mode is to rely on construction workers to report and enthusiastic people to report road conditions, but the main disadvantages are: (1) mainly for national roads, expressways and provincial roads And other major roads to report, for some county roads, rural roads, lanes, and mountain roads and other minor roads, road conditions information, less ink or insufficient data; (2) the information query method is mainly described in terms of items, according to The notification time is arranged in order (Table 1 below), but for the use of navigation software by passersby, the above information has not been integrated into the route planning considerations of the vehicle-mounted navigation software, resulting in the failure to provide real-time traffic information for passersby And route planning to further save driving time and energy consumption; (3) at present, enthusiastic people mainly take the initiative to report by telephone, but the real-time traffic conditions of the police (as shown in Table 1 below) know that the enthusiastic people who are willing to call and report actively It has not yet spread to everyone, but in terms of the density and resources of a smart phone with positioning capabilities, if we can make good use of and integrate the vastness of "everyone is a road conditioner" and "one man and one machine" Resources, even for small projects such as asphalt paving or buried water pipes in lanes, if real-time and accurate road condition cloud data bases can be provided if everyone can provide “easy positioning and return” road condition information methods.

Table 1

The so-called real-time traffic information includes information such as road conditions, vehicle speed, traffic volume, and estimated road closure time. It is an important part of the intelligent transportation system. It can provide real-time traffic information for passersby to save driving time and energy consumption. Based on this information, value-added service providers can provide services such as vehicle navigation, fleet dispatch, and traffic control. The basis of this type of traffic information service is the collection of big data of real-time traffic information, such as real-time road conditions and traffic flow. At present, the traditional methods for collecting real-time traffic information mainly include setting a fixed vehicle detector and a global positioning system (Global Positioning System, GPS) probe vehicle to report traffic information.

The above-mentioned collection of real-time traffic information is mainly completed through fixed vehicle detectors and detection vehicles. Although it can achieve real-time traffic conditions notification, and then integrate a real-time traffic information for reference of passersby, however, it still has The following defects need to be improved:

First, the installation cost is high. The use of fixed vehicle detectors for the return of traffic information usually requires the installation of fixed vehicle detection devices on important road sections to detect the traffic volume and speed of the road sections; the installation and maintenance of these devices usually require huge installation costs. cost. Similarly, in the mechanism of reporting traffic information using detection vehicles, multiple manned / unmanned detection vehicles must be dispatched on different sections at the same time to periodically report real-time traffic conditions to a transportation information center; these manpower and Dispatch of vehicles usually also requires huge installation costs.

Second, the timeliness of updating traffic information is not good. Once a detection vehicle is used to report traffic information, a sufficient number of detection vehicles must be used, and the vehicle must repeatedly drive and report traffic conditions on the set road section, so that the traffic information center can obtain sufficient road condition information and update the traffic conditions in real time; However, in the mechanism of using the detection vehicle to report traffic information, once the number of detection vehicles dispatched in a specific area is insufficient, the timely road condition information that can be collected is insufficient, resulting in the shortcoming of timely updating of traffic information. If the number of detective vehicles dispatched in a specific area is sufficient, although the road condition information can be collected sufficiently, the relative installation cost will also increase sharply.

The purpose of the present invention is to provide a method for reporting and forming real-time traffic conditions, which can mainly collect the most complete traffic information at the least cost to integrate the most accurate and timely traffic information.

Another object of the present invention is to provide a method for reporting and forming real-time traffic conditions, which mainly utilizes the density and resources of "everyone is a traffic reporter" to collect the most complete and timely traffic information.

The reason is that in order to achieve the foregoing objective, a method for reporting and forming real-time traffic conditions according to the present invention includes: an uploading step, after a pedestrian, a driver, an executive officer, or a road maintenance person finds at least one failure point, The coordinates of the fault point are uploaded to a road condition cloud database; and a merging step is to merge the coordinates of the fault point received by the road condition cloud database with a map to form a road condition map having the fault point.

Preferably, in the uploading step, the pedestrian, driver, executive official or road maintenance personnel uploads the road condition information of the fault point to the road condition cloud database.

Preferably, the road condition information of the fault point includes a traffic jam location, a traffic jam cause, a traffic jam condition, an estimated traffic jam time, a traffic jam condition has been removed, or a photo of an actual road condition.

Preferably, when the fault point in the uploading step is uploaded by the pedestrian or the driver, it further includes a verification step provided between the uploading step and the merging step, and the verification step is performed when the road condition cloud The database only executes the merging step after receiving the coordinates of the fault point uploaded by different pedestrians or drivers accumulated multiple times.

Preferably, the verification step requires a plurality of verifications, including setting a plurality of different verifications in consideration of the design standard classification and actual traffic volume of different roads such as rural, county, provincial, expressway, or national highways. threshold.

Preferably, the coordinates of the fault point are different but are included in the same road section, and the number of times can be accumulated.

Preferably, when the failure point in the uploading step is uploaded by the executive official or road maintenance personnel, it further includes a verification step provided before the uploading step, which verifies the executive official Or the account password of the road maintenance personnel, the upload step will not be performed until it is correct, and the upload step cannot be performed if it is incorrect.

Preferably, it further includes a transmission step provided after the merging step, and the transmission step wirelessly transmits the road condition map received from the road condition cloud database to other drivers ’portable devices and data from the National Highway and Highway Bureau. Library, the General Directorate of Highways, or navigation software.

Preferably, it further comprises a downloading step provided after the merging step. When the road conditions cloud database maps the received road conditions, other drivers ’portable devices, the National Highway and Highway Administration database, and highways The database of the General Administration or navigation software will automatically download the traffic map in the traffic cloud database.

Preferably, in addition to the estimated driving time based on the distance between the two places, the navigation software also includes information such as traffic jam conditions and estimated traffic jam times provided by the real-time road map considering traffic jams, construction, or road closures. More driving information and route planning solutions for drivers.

Accordingly, the present invention transmits the coordinates of the found or previously known fault point to the road condition by a pedestrian or driver walking or driving to the fault point, or an executive official or road condition maintenance person who knows the fault point in advance. Cloud database, and the coordinates of the fault point as a basis for merging with the map to form a road condition map with the fault point. Therefore, the setting of the fault point on the road condition map does not require the use of fixed vehicle detection. It can be provided by a vehicle or a detection vehicle, but uploaded by a pedestrian or driver who walks or drives to the failure point, or by an executive official or road maintenance person who knows the failure point in advance, so that it can be collected at a minimum cost. To the most complete traffic information to integrate the most accurate and timely traffic information.

Regarding the technology, means, and other effects adopted by the present invention to achieve the foregoing objectives, four preferred feasible embodiments are described in detail below with reference to the drawings.

Before proposing a detailed description, it should be noted that in the following description, similar steps or elements are represented by the same number.

Referring to FIG. 1 to FIG. 4, a method for reporting and forming real-time traffic conditions provided by a first embodiment of the present invention is mainly composed of an uploading step 10, a verification step 20, a merging step 30, and a transmission. Composed of step 40, where:

In the uploading step 10, after the pedestrian 51 or the driver 52 finds two failure points 61 and 62, the coordinates of each of the failure points 61 and 62 are uploaded to a road condition cloud database 70. In this embodiment, it is assumed that the pedestrian 51 Or driver 52 has to go from location A to location B, and there are many longitudinal and horizontal staggered and interconnected paths between location A and location B, and the pedestrian 51 or driver 52 finds that one is under construction The first failure point 61 and the second failure point 62 of the accident. The pedestrian 51 or the driver 52 uploads the coordinates (longitude and latitude) of each of the failure points 61 and 62 to the road condition using a mobile device with a network function. The cloud database 70 also uploads the road condition information of the fault points 61 and 62 to the road condition cloud database 70 in the same manner; the road condition information of the fault points 61 and 62 is shown in FIG. 5 and includes the traffic jam location, The cause of the traffic jam, the traffic situation, the estimated time of the traffic jam, the traffic situation has been lifted, or the actual road traffic photos.

The verification step 20 is performed after the road condition cloud database 70 receives the coordinates of the fault points 61 and 62 uploaded by different pedestrians 51 or the driver 52 and accumulates a plurality of times, and then executes the merge step 30; in this embodiment, 5 times as an example, but not limited to this. The verification step 20 requires multiple verifications, including the classification of design standards based on the consideration of different roads such as rural roads, county roads, provincial roads, expressways or national highways. And actual traffic flow, set different verification thresholds. It should be noted that the cumulative number of uploads of the failure points 61 and 62 refers to whether five uploads of the failure points 61 and 62 are satisfied in the same section, that is, the coordinates of the same failure points 61 and 62 or are different. The coordinates of the fault points 61 and 62 but included in the same road section can be accumulated.

The merging step 30 combines the coordinates of the fault points 61 and 62 received by the road condition cloud database 70 with a map 71 to form a road condition map 72 with the fault points 61 and 62. The merging step 30 is based on the coordinates of the fault points 61 and 62 and the original coordinates of the map 71 as a reference.

The transmitting step 40 wirelessly transmits the road condition map 72 received from the road condition cloud database 70 to the portable device 81 of other drivers, the database 82 of the National Highway Administration, the database 83 of the General Administration of Highways, or navigation software 84. In addition to the estimated driving time based on the distance between the two places, the navigation software also includes information on traffic conditions, estimated traffic jams and other information provided by considering real-time traffic maps for traffic jams, construction, or road closures, providing drivers with more information. Yuan's driving information and route planning plan.

It is worth noting that, in this embodiment, the uploading step 10 is uploaded to the road condition cloud database 70 through the mobile device of the pedestrian 51 or the driver 52, and the verifying step 20, the merging step 30, and the transmitting step 40 are performed through The road condition cloud database 70 is executed.

As a result, when the pedestrian 51 or the driver 52 uploads the coordinates of the two fault points 61 and 62 found to the road condition cloud database 70, and the road condition cloud database 70 receives the coordinates of each of the fault points 61 and 62, After 5 accumulations, the coordinates of the fault points 61 and 62 are combined with the map 71 to form a road condition map 72 with the fault points 61 and 62. The road condition cloud database 70 wirelessly maps the road condition map 72 The portable device 81, the database 82 of the National Highway and Highway Administration, the database 83 of the General Highway Administration, or the navigation software 84 are transmitted to other drivers, so that relevant users or relevant units can take corresponding actions.

In addition, in this embodiment, the coordinates of the fault points 61 and 62 found by the pedestrian 51 or the driver 52 are transmitted to the road condition cloud database 70, and the coordinates of the fault points 61 and 62 are used as the basis for the merger. Combined with the map 71 to form a road condition map 72 with the fault points 61 and 62. Therefore, the setting of the fault points 61 and 62 on the road condition map 72 need not be provided by a fixed vehicle detector or a detection vehicle. , But uploaded by pedestrian 51 or driver 52 who walked or driven to the failure point 61, 62, so that the most complete traffic information can be collected at the least cost to integrate the most accurate and timely Traffic information.

It is worth mentioning that, in the first embodiment, since the performer uploading the failure points 61 and 62 is a pedestrian 51 or a driver 52, that is, an unspecified person, therefore, after performing the uploading step 10, set With the verification step 20, after the road condition cloud database 70 receives the coordinates of the failure points 61 and 62 uploaded by different pedestrians 51 or drivers 52 and accumulates a specific number of times, the merge step 30 is performed to reduce Possibility of false information at the failure points 61 and 62.
