Method for formulating front road condition broadcast information and vehicle-mounted device

Abstract

The invention provides a method for formulating front road condition broadcast information, which comprises the following steps: after determining the attention range and attention change rule of a driver, extracting road condition information in the attention range of the driver, and determining the broadcast detail degree of the road condition information from near to far according to the attention change rule. The method specifically comprises the following steps: S1, determining the attention range of a driver according to the driving characteristics of the driver by utilizing an isochroneanalysis method; S2, analyzing attention change rules of drivers in the attention range to the far and near areas; and S3, determining a broadcasting strategy of the detail degree of the road condition information in the attention range. The method and the system have a guiding effect on customizing the road condition broadcast information by the driver.

Description

technical field [0001] The invention relates to the technical field of urban road condition information, in particular to a method for quantifying drivers' attention to road condition information. Background technique [0002] Today, China has entered the era of automobile popularization, and traffic congestion is a common problem faced by major cities. Although drivers can rely on navigation software and traffic radio to choose an efficient travel route to a certain extent, most drivers will not open the navigation software because they think it is troublesome to set up or are familiar with the destination, so they cannot understand the road conditions ahead; The information is not broadcast for the current location of individual drivers, resulting in most drivers not knowing the whole picture of the road ahead. At this time, when the road section that the driver chooses based on his experience happens to be congested, he can no longer exit, which delays his trip; and a la...

Problems solved by technology

Although drivers can rely on navigation software and traffic radio to choose an efficient travel route to a certain extent, most drivers will not open the navigation software because they think it is troublesome to set up or are familiar with the destination, so they cannot understand the road conditions ahead; Does not broadcast information for the current location of individual drivers, resulting in most drivers not knowing the overall picture of the road ahead

At this time, when the road section that the driver chooses based on his experience happens to be congested, he can no longer exit, which delays his trip; and a large number of vehicles with unknown road conditions pour in one after another, increasing the degree of congestion and the amount of traffic on the way, making it more difficult for traffic evacuation
