According to different criteria for classifications, travelling route can be divided into a variety of different types：
（1）By the distance of travelling route, short distance travelling route, intermediate range travelling route, long haul travel line can be divided into；
（2）Whole by travelling route calculates travel time, can be divided into tourism trip line on the one, tourism trip line on the two, travel within 3rd
Swim line and Duo tourism trip lines；
（3）By the property of travelling route, common sightseeing tour line and special-topic tourism line can be divided into；
（4）By travelling route to the size of tourist's attractived region, international tourism can be divided into and swim line.Trip in national travelling route and area
Swim line；
（5）By the space layout form of travelling route, reciprocation type travelling route, single-channels can be divided at 2（Single line is through）Trip
Swim line, ring channel-type（Annular pass-through formula）Travelling route, single hinge type（Single-point axis-spoke）Travelling route, more hinge types（Multiple spot axis spoke
Formula）Travelling route and network distribution type travelling route.
Existing various tourism paths planning methods are mainly manifested in following aspect there are some drawbacks：
1. free walker tourist's actual practice
Compare clearly route in order to still have in other places, generally requires a large amount of information collection work.It is past after collection
Toward actually travel during, it is possible to the case where detouring.It can not be well to time cost, path length cost
Control enumerates all situations and unrealistic, more tour pal's choosings because the case where seeming the route planning at multiple sight spots by manpower
It selects the experience with reference to forefathers, look into the ways such as strategy.Or be only determined before setting out go to which sight spot and sight spot it
Between do not determine sequentially, do not formulate the route of control time cost, and probably either detoured by tape error road.
2. the current way of travel agency and the route planning of free walker tourist and the specific practice of adjustment.
The path design of the actually present design for complete tourism route, more sight spots is often conducted a sightseeing tour and travel agency
Experience and interest relations carry out corresponding stroke design.It is full for whole time cost, path length cost, past tourist
The factors such as meaning degree, the consideration for the progress entirety that is not considered into directly, in other words, the considerations of for route more
It is to set out for the empirical angle of people.This process needs a large amount of experiences before travel agency's either traveller's planning and travelling
The collection and judgement of person oneself.The time cost for making route is very high, the calculating that each key factor could not be quantified.More
When, being in the push for road conditions can plan route according to driver, can not rule out erroneous judgement of the driver to road conditions.And
And tour guide can be according to current stroke or be that a friendly situation does some dynamic adjustment and cancels or increase some sight spots
The way of the so-called route planning of some app on the market.
3. planning of the existing software to path
Existing software actually manually secures sight spot and visit sequence to a path planning at scenic spot in market, is not to lead to
It crosses algorithm and carries out dynamic Route Generation, this method does not support passenger to change the dynamic in the selection of sight spot.Only true
Navigation between two sight spots is provided in the case of alignment road, fixed sight spot.There is no account for it to all paths
Afterwards preferentially.It is practical and not smart enough.And passenger is not experienced to the process for taking into account coordinates measurement in Path selection specifically
In the middle of.

In the present embodiment, the i-th row jth arranges in the multiple-factor composite cost table, represents i-th of sight spot to j-th of scape
The multiple-factor composite cost value of point, the element on diagonal line are 0.
The method that a specific embodiment illustrates the present invention is given below, mainly includes the following steps：
1st step, the optional sight spot manually determined are：The magnificent squares Shi Zhengmen, China Shi Kongzi are as sculpture, hall of the libraries Hua Shi, China
Teacher's Cultural Square.Some sight spots that the above sight spot can manually be planned when being using Hua Shi as scenic spot.（If by wide
State is and not quite alike directly as scenic spot, and the optional sight spot that may manually determine can be again：Guangzhou Zoo, Beijing
Road shopping mall, martyrs' park, The Chen Clan Temple etc..）
2nd step, tourist select according to time of oneself interest before visit first few minutes are either gone sight-seeing, may teacher to China
Cultural Square is less interested, then just only have selected magnificent Shi Kongzi as sculpture, hall of the libraries Hua Shi, the China squares Shi Zhengmen this
Three sight spots, do not include into all sight spots.3rd step system background is called the inspection of Baidu's public transport path
Rope all calls the masstransitSearch functions in Baidu map API between any two sight spot, uses
OnGetMassTransitRouteResult obtains the route search result of readjustment.In this example, since previous step is swum
Visitor has selected 3 sight spots（Magnificent Shi Kongzi is as sculpture, hall of the libraries Hua Shi, the China squares Shi Zhengmen）, also just there are 6 routes to examine
Rope（Magnificent Shi Kongzi is as sculpture --- hall of the libraries Hua Shi（It is two-way）, China Shi Kongzi is as sculpture --- the magnificent squares Shi Zhengmen（It is double
To）, hall of the libraries Hua Shi --- the magnificent squares Shi Zhengmen（It is two-way））Obtain the value of 6 time span costs（Unit is km）.
4th step, system background call synchronization call syncGetUserScore (int mapIndex, int
StartIndex, int endIndex), by incoming parameter mapIndex determinations be currently with which scenic spot,
StartIndex and endIndex corresponds to the index value of starting point and target point, and the user of request to system background comments in this way
Valence average mark, wherein user itself seem that initial value is 1 (for maximum value) in software platform to the evaluation points in path, are used
Family can carry out individually a section path when terminating to navigate the evaluation of 5 stars, the evaluation of 5 stars correspond to 1,0.8,0.6,
0.4,0.2,0 score value, and its average value is calculated, using average value as user's evaluation.
Then, user's evaluation be multiplied by 0.1 add before length value at cost, obtain 6 multiple-factor composite cost values, insert
In multiple-factor composite cost table.（Table the i-th row jth arranges, and first, ij is that sight spot is suitable in the sight spot that tourist selectes respectively
Sequence, example China Shi Kongzi are 1 as sculpture is hall of the libraries 0, Hua Shi, and the magnificent squares Shi Zhengmen are 2.Secondly, the i-th row jth row,
I-th of sight spot is represented to the multiple-factor composite cost value at j-th of sight spot, the element on diagonal line is 0）
The calculating section of 5th step, intelligent path planning.When 4 step we have been able to obtain a composite factor at
This table.Then, all subset Si of sight spot collection are generated, are exactly in this example（{},{0},{1},{2},{0,1},{0,2},{1,2},
{ 0,1,2 }, we are directly indicated with positional value of each sight spot in tourist selectes sight spot to simplify, behind be also such）.From a left side
To the right side, since small subset Si, big subset Si is traversed, is calculated as follows：
It is overlapped operation not in the element ej of subset Si to all, finds out minimum value after superposition, and after recording the superposition
Minimum value.(and which sub- result of calculation is the minimum value for recording the value simultaneously be as obtained from, we term it lastMap
Table)
The result that history can be used when the sweeping subset in face after computation be exactly the superposition of the scale is smaller of front most
Small value result.This process, that is, Dynamic Programming.And wherein can indicate subset with a kind of representation method being called compressive state,
It can accelerate the speed of service calculated in code level.
Then it show that sequence is gone sight-seeing at complete sight spot by lastMap tables, by the sequence, generates tourist's energy in app
The real visit sequence seen（Magnificent Shi Kongzi is as sculpture --- hall of the libraries Hua Shi --- magnificent squares Shi Zhengmen）, tourist this
Storing path can be pressed when a, app can be locally stored in using json as the data of format, and file name is
localPath.json.Have recorded mapIndex（Scenic spot indexes）:int , view（Sight spot）:{viewIndex（Sight spot sequence
Number）:Int, viewName (sight spot name):Int }, sequence（Sight spot sequence number sequence）:[int,int,…int]}.From
In the case of line, as long as the offline map that tourist has also carried out internal system in advance is downloaded, then can be carried out offline
Route planning navigation.Even if beneath no network the case where, as long as having downloaded arrangement path in advance.
In conclusion the tourism intelligence paths planning method of the present invention, which is more bonded user, actually uses scene, obtain
Circuit is more humane：
1. in the factor generates settlement process, evaluation points of the user to path itself are added.It is not only in route selection
The factors such as length of time, and system is also added in the user's evaluation factor.
