Description

METHOD, SYSTEM AND DEVICE FOR PROVIDING TRAFFIC INFORMATION IN REAL TIME BACKGROUND OF THE INVENTION [0001]

The present invention relates to a real-time traffic information providing method, system and device.

Traffic jams mean that there are lots of cars and roads are blocked. In the case of Korea, traffic congestion is very severe over commuting time, and severe traffic jams occur especially during holidays.

In the case of traffic congestion, there is an unnecessary increase in vehicle operation cost and time loss which can be reduced when the vehicle runs at normal speed because there is no traffic congestion. This is called Traffic Congestion Costs. This traffic congestion cost is steadily increasing every year. In 2010, traffic congestion costs amounted to 28 trillion won, accounting for 2.43% of total GDP.

Currently, traffic congestion information is provided using TPEG (Transport Protocol Expert Group) to reduce traffic congestion and traffic congestion costs. TPEG is a service that displays traffic information and traveler information provided by broadcasters on a DMB (Digital Multimedia Broadcasting) data broadcasting signal and displays it on a navigation terminal equipped with a DMB receiving chip.

However, the congested traffic information obtained through TPEG is determined by measuring the number of vehicles per unit time that the equipment is installed in tens of thousands of taxis, buses, and logistics vehicles and passes through the probe. However, there are waiting times for taxis and buses to board passengers, which reduces the reliability of traffic congestion information.

In addition, traffic congestion information using TPEG measures congestion on all major roads, so there is a huge cost for collecting this information and it is inevitable that it is reflected in charges.

Crowd sourcing, on the other hand, is a combination of public and outsourced, which means that the public is involved in some of the business activities such as production and services. Crowd sourcing is not only less costly than outsourcing, but also has more and more information, and many companies are using it recently.

And a device for outputting traffic congestion status based on slow-moving section data and congestion section data received from the traffic information providing server.

[ For example, the traffic information providing server can determine whether the traffic congestion notification signal exceeds 200 within 30 minutes within a radius of 5 km.

When the traffic congestion notification signal exceeds a predetermined number, the traffic information providing server may determine the point 420 at which the traffic congestion notification signal has a high distribution within the predetermined range as the slow reference point or the congestion reference point 430 .

For example, the traffic information providing server may determine that the traffic is congested within a radius of 5 km, if the traffic congestion report signal exceeds 200 within 30 minutes within a radius of 5 km, (420) having a high distribution of the traffic congestion report can be determined as the slow reference point or the station reference point (430).

5 is a view for explaining a method of determining a division point according to an embodiment of the present invention.

The traffic information providing server calculates the distance between the slowing reference point 500 and the stagnation reference point 510 and uses the slowing reference speed and the stagnation reference speed to divide the slowing segment and the stagnation segment, Can be determined.

For example, the slow reference speed may be an average speed of 27 km / h, which is a standard for collecting information through traffic congestion notification, and the congestion reference speed may be an average speed of 10 km / h.

The traffic information providing server can determine the division point 520 by interpolation using the slow reference speed and the congestion reference speed.

For example, when the vehicle is moving from the slowing reference point 500 to the stagnation reference point 510, the traffic information providing server can calculate that the distance between the slowdown reference point 500 and the stagnation reference point 510 is 4 km have.

In addition, the traffic information providing server can determine the point at which the traffic jam speed is 10 km / h or less by using the interpolation method based on the slowing reference point 500 as the sorting point 520.

For example, when it is determined that the current average speed at the slow reference point 500 is 25 km / h and the current average speed at the stagnation reference point 510 is 5 km / h, the traffic information providing server calculates Y = -5 * x + 25 interpolation can be applied. The traffic information providing server can determine the point 520 as a point 3 km away from the slow-motion reference point 500, which is the point at which the interpolation method becomes 10 km / h or less.

The equation of the interpolation method for explaining FIG. 5 is only an embodiment of the present invention and is not limited thereto. That is, the current average speed at the slowdown reference point 500, the current average speed at the stagnation reference point 510, and the distance from the slowdown reference point 500 to the stagnation reference point 510 can be varied.

For example, the traffic information providing server determines the slowing reference point 620 from the slow reference point 600 to the sorting point 610 and moves the stagnation reference point 620 to the segmenting point 610 from the stagnation period 630 ).

7 is a diagram illustrating an example of a display unit in which a device according to an embodiment of the present invention outputs traffic congestion status.

The device can output the traffic congestion status based on the slow section data and the congestion section data received from the traffic information providing server. The traffic congestion status output to the device may include at least one of the slow-down reference point 700, the congestion reference point 710, the segment point 720, the slow-motion segment 730, and the congestion segment 740.

For example, the device displays a slowing reference point 710, a stagnation reference point 720, a segmenting point 730, a slowing segment 740, and a stagnation segment 750 Can be output.

The slowing reference point 710 may be output more stably than the stagnation reference point 720 and the slowing section 740 may be outputted more lightly than the stagnation section 750 to intuitively grasp the traffic congestion degree. For example, the slow reference point 710 may be grayed, the stagnation reference point 720 may be red, the longitude segment 740 may be orange, and the stagnation zone 750 may be red.

The device may also output a map 760 of a larger radius by reducing the map 700 of a constant radius.
