Implementation method of driver danger prediction test system

A test system and implementation method technology, applied in the field of diagnosis, can solve problems such as the inability to reveal the process of the subject's reaction, the inability to obtain information on how the subject thinks, and the inability to determine the subject's response to dangerous events. The effect of ambiguity, avoidance of handling problems

Problems solved by technology

[0006] However, there are certain limitations in this response time test
First, the test cannot reveal the course of the subject's response, only a final response time outcome
This means that the test cannot obtain information about how the subject is actually thinking, and cannot determine whether the subject is actually responding to a dangerou

Example Embodiment

[0064] Example 1

[0065] like figure 1 As shown, a driver hazard prediction test system implementation method, including the following steps:

[0066] S1, Test: Subjects log in to the driver's hazard prediction test system on smart devices, the driver's hazard prediction test system randomly selects a test video group, the test video group contains several test video, test video random play, each test After the video playback is completed, the video freeze, the video freezing time is the moment of traffic conflict, and the subject predicts traffic conditions in 5 seconds after traffic conflict, and enter hazard prediction results, videos by entering text or selection options After freezing, automatically play the next test video until all test video playback and freeze, the test ends, the driver's hazard predictive test system automatically stores all the dangerous prediction results of the subject to form test results;

[0067] Smart devices include: mobile phones, tablets and c...

[0087] Example 2

[0088] like figure 2 As shown, a driver's hazard prediction test system implementation method,

[0089] A) The specific test flow of the driver hazard prediction test system developed by this technical plan figure 2 As shown, it is divided into 11 steps.

[0090] (1) When the test is officially started, the system will automatically select a set of (25) test video to test a set of (25) test video in 100 alternative test video (4 sets of tests divided into parallel). These 100 test videos are from the real traffic scenario video, the test video comes from Beijing, Shenyang, Shanghai and Chengdu, and details are shown in Table 1. Each video contains a traffic conflict scenario, that is, the vehicle in the first perspective of the video must take some actions to avoid danger. These videos are in advance by the training experts in the transportation security field as a representative traffic conflict condition and can distinguish Dangerous forecasting level, and is ...

Abstract

The invention provides an implementation method of a driver danger prediction test system. The method comprises the following steps that: a subject logs in the driver danger prediction test system on intelligent equipment, the driver danger prediction test system randomly selects a test video group, and after each test video is played, the test video is frozen; and the time when the video is frozen is the time when the traffic conflict occurs, the subject predicts the traffic condition within 5 seconds after the traffic conflict occurs, and inputs an answer by inputting characters or selecting options; the next test video is automatically played after freezing is finished, and the above operation is performed until all the test videos are played and frozen, then the test is finished, a test result is formed, judging is performed, and a test score and a subject safety level are outputted. According to the invention, a testee can complete the test only by using an Android system mobile phone, the method is suitable for different educated drivers and is suitable for larger-scale test, the answer obtained by the test contains the understanding of the testee on the current road condition, and the test fuzziness during reaction is avoided.

Description

technical field [0001] The invention relates to the technical field of diagnosis, in particular to a method for realizing a driver risk prediction test system. Background technique [0002] Hazard prediction refers to the driver's ability to accurately anticipate potential hazards in the road environment and grasp how the hazard will develop during driving. The hazard prediction test is an alternative to the traditional reaction time-based hazard perception test. The basic premise of the test is that even the safest drivers do not wait for hazards to occur before reacting, but instead try to predict what will happen based on cues in the visual scene. [0003] A driver's hazard prediction test was first developed by British researchers in 2009 and incorporated into the driver's license test. This hazard prediction test requires subjects to watch a series of traffic videos taken from the driver's point of view. The images of these videos will turn black or freeze when there ...
