Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example of Evaluation Method for Road Emergency Evacuation Capability

[0026] refer to figure 1 , figure 1 It is a flow chart of steps according to an embodiment of the road emergency evacuation capability evaluation method of the present invention, including the following steps:

[0027] Step 110: Obtain multiple evaluation indicators for evaluating road emergency traffic conditions;

[0028] Step 120: According to the multiple evaluation indexes of the road emergency traffic state, use the principal component analysis method to obtain the principal components of the time dimension and the principal components of the space dimension, and then determine the comprehensive index of road emergency evacuation capacity.

Abstract

The invention discloses a method and a system for evaluating road emergency evacuation capacity and a method and a system for grading the road emergency evacuation capacity. The method for evaluating includes steps of acquiring a plurality of evaluation indexes used for evaluating road emergency traffic states, acquiring a time dimension principal component and a space dimension principal component by aid of a principal analysis method according to the evaluation indexes of road emergency traffic states, and then determining integrated index of road emergency evacuation capacity. The method for evaluating utilizes the principal component analysis to process mass data and expresses the integrated index of road emergency evacuation capacity in incidents by aid of combination of the time dimension principal component and the space dimension principal component. The higher the integrated index is, the higher the corresponding road emergency traffic service level is, therefore, the method is more adaptable to evacuation and rescue of traffic flow in emergency.

Description

technical field [0001] The invention relates to the technical field of traffic supervision, in particular to a road emergency evacuation capability evaluation method and system, and a grading method and system. Background technique [0002] In the field of transportation, the grade of road service level widely used at present is mainly to measure the traffic state of the road from the perspective of speed and flow, and to measure the effect of road traffic with the evaluation criteria in the HCM manual. The smoothness of the traffic flow it focuses on is evaluated from the perspective of the driver. When an emergency occurs, because the traffic rules of rescue vehicles and social vehicles are different, and the traffic control department cares more about the time efficiency, stability, and reliability of the road, the division standard of the road traffic service level in the usual sense is No longer applicable. [0003] Comprehensive evaluation is produced and developed a...
