Abstract

The invention provides a driver cognitive characteristic based predicting and calculating system for running speeds of vehicles on desert roads. The predicting and calculating system comprises a desert road basic data entry and storage subsystem, a desert road driver road safety cognition subsystem, a desert road driver vehicle speed control subsystem and a desert road prediction vehicle speed output subsystem which are sequentially connected. The system is quick in response, high in accuracy, convenient to operate and capable of effectively reducing traffic accidents and being adopted by road traffic management departments, research institutions and peers abroad and has obvious industrial generality and social welfare. The maximum mean relative error of the system relative to actually measured speeds and simulation and prediction calculated speeds on identical sections is 14.37%, the minimum mean relative error of the system is 2.83%, the total mean relative error of the system is 7.62%, and the consistency between perdition results of running speeds and actually measured results of actual speeds is high.

Description

technical field

[0001] The invention belongs to the field of road traffic safety, and relates to a vehicle speed prediction system, in particular to a desert road vehicle speed prediction calculation system based on driver's cognitive characteristics. Background technique

[0002] At present, the traditional road speed prediction model has certain one-sidedness, has the defects of low calculation accuracy, and the model is too complicated to be realized. In addition, the traditional road speed prediction model mainly considers the influence of road alignment elements, and rarely involves the influence of the driver on the model. The most direct factor affecting the speed of the vehicle is the driver himself. The driver perceives and evaluates the road alignment elements. Decisions are then made to steer the vehicle for speed adjustments.

[0003] The traffic conditions of desert highways are quite different from those of ordinary highways, and there are few studies on the s...

Examples

Embodiment

[0078] Take a secondary desert road in Xinjiang as an example:

[0079] ① see Figure 8 , run the software, execute the [Road Information Entry] command in the [Road Basic Data Entry and List Display] drop-down menu bar, and the [Road Overall Information Entry Dialogue Window] dialog box will pop up. According to the actual road information of the desert road, input or set the basic information of the predicted desert road section in each text box according to the field requirements.

[0080] ② see Figure 9 , click【Enter Road Section Information】command, and the dialog box 【Enter Road Section Data】will pop up. According to the road structure parameters and environmental conditions of the predicted road section, input or set the road structure information, road section type and number and other information of the road section according to field requirements in each text box.

[0081] ③ see Figure 10 , and click the [Road Section Status List Output] command to realize the ...
