Description
Technical field
The assessment technology designed the present invention relates to campus maidenlinessization more particularly to a kind of open campus maidenlinessization design more
Objective appraisal method.
Background technology
Enclosing-wall culture in Chinese traditional culture occupies dominant position by gated community pattern in China.It is closed for reply
Formula region drawback alleviates urban transport problems, and central urban work meeting in 2016 proposes the opinion of " promoting block system ", bright
Really " Unit Yard will be opened gradually, realize internal passageway public, solve traffic network location problem, promote soil saving
Using " requirement.It is selectively that colleges and universities' part road is open to the society for closing campus, path resource can be improved
Utilization rate promotes regional traffic microcirculation, reduces vehicle delay, promotes school and extraneous cultural exchanges, enhance urban vitality.
But external vehicle can pass through inside campus and bring the negative effects such as security risk, noise pollution and environmental pollution.Open campus
Maidenliness highway layout lures that driver keeps low speed to pass through into from psychological levels, reduces the security risk that people's vehicle mixes row, avoids passing
The additional noise pollution that system maidenliness measure brings the physiological discomfort sense of driver and generates therewith, reduces vehicle pass-through and generates
Oil consumption and exhaust emissions amount, realize campus path resource and social sharing.
But demand of the road of different zones to maidenliness is different in campus, it is right respectively that the selection of measure is also required to
It waits for.It is best in order to make maidenliness measure achieve the effect that, it needs to carry out maidenlinessization design effect to the road for carrying out maidenliness design
Fruit is evaluated, to differentiate the quality of its maidenlinessization design.There is presently no the evaluations designed for open campus road maidenlinessization
Method, therefore there is an urgent need for a kind of targeted and effective evaluation methods to evaluate maidenliness effect.

Finally utilize aggreggate utility functional value formulaNot open, open and maidenliness is calculated to melt and put
The corresponding aggreggate utility functional value of these three evaluation objects.
The beneficial effect comprise that：
1) consider " traffic efficiency, environmental benefit, economic benefit ", multi-object evaluation model is established, to design scheme
Evaluation have comprehensive and validity, evaluation result have authority.
2) evaluation carried out to traffic status considers from intersection index, section index, zone index, utilizes
Traffic simulation software VISSIM emulates the traffic before and after open campus, by emulate data illustrate open campus with
After can improve region traffic jam issue, have intuitively illustrate effect.
3) every evaluation index in traffic efficiency, social environment benefit and economic benefit is normalized, profit
Weight coefficient is calculated with entropy assessment and then carries out overall merit, obtains aggreggate utility functional value, and analysis respectively calculates open campus
Front and back, maidenlinessization improves the aggreggate utility functional value before and after open campus, is brought with maidenliness measure to evaluate open campus
Comprehensive benefit.It can will visualize and the improvement situation of phenomenon is converted into digitized forms, it is more intuitive and more convincing
Compare the cost performance and various aspects effect of open route in ground.
