Processing method provided in this embodiment for netting the investment of grade highway maintenance, to control railway network planning phase annual maintenance
Expense and for the purpose of meeting road conditions target call, to dominate the road surface of maintenance costs, two large-engineering of bridge tunnel as point of penetration, according to two
The data such as the maintenance input over the years of large-engineering, the volume of traffic, road conditions index (PQI, BCI), establish MQI simplified mathematical models, expense
Prediction model and volume of traffic model of growth, and carry out three ladders of " MQI target controls, the intervention of subitem target, fund object filtering "
Degree target is preferred, and the final road conditions horizontal combination obtained while meeting road conditions and fund target, the guiding plan phase conserves fund
Orderly input, solving current traditional curing capitalized method cannot quickly judge to meet certain fund and the road under road conditions goal condition
Face, bridge tunel engineering conserve fund input problem.
The present embodiment further illustrates the above method by taking 5 highways that certain Speedway Control Broad is administered as an example
Carry out the processing procedure and handling result of maintenance investment.The highway route coding be respectively designated as G1, G2, G3, G4 and
G5, definition are road network A by the road network that 5 highways form.5 path lengths that road network A includes be respectively 20.5km,
25.3km, 28.7km, 26.4km and 32.1km.Method includes：
(1) it determines road network object, collects historical information
The maintenance of surface expense and maintenance of bridge and tunnel expense of road network A are collected respectively, as shown in table 1.The each of road network A is collected respectively
The route volume of traffic over the years and road condition data (the first index and the second index), as shown in table 2
