Real-time road judge the crossing to be evaluated in the first electronic map and in the second electronic map each entrance seat
The whether all slow or congestions of the road conditions of punctuate, if then prompting the signal period at the crossing to be evaluated small.If otherwise into
Enter step S10.
S10: judge that the first electronic map neutralizes the coordinate points shown in the second electronic map as slow or congestion entrance
Whether direction is consistent, prompts the split that coordinate points are slow or congestion Way in small if consistent, otherwise return step
S3。
That is, when each outlet at crossing to be evaluated is unimpeded, if each Way in slowly or
Person's congestion then illustrates that the signal lamp cycle at the crossing to be evaluated is small.When each outlet at crossing to be evaluated is unimpeded, if
Way in be it is smooth, Way in be slow perhaps congestion then illustrate slowly or congestion direction it is green
The lamp time is short, i.e., split is small.Using the above scheme of the present embodiment, can be obtained according to the real-time road at crossing to be evaluated
The control effect of the semaphore at crossing to be evaluated is good or poor.Correspondingly, the semaphore at crossing to be evaluated controls effect
When fruit difference, additionally it is possible to obtain the reason of control effect difference according to real-time road, and be prompted to traffic administration responsible person.

Second judgment unit, when the judging result of the first judging unit is to be, according to coordinate points each in the second electronic map
Real-time road judge crossing to be evaluated described in the second electronic map each exit coordinate points road conditions it is whether complete
Portion is unimpeded；
Third judging unit, when the judging result of second judgment unit is to be, according to coordinate points each in the first electronic map
Real-time road judge crossing to be evaluated described in the first electronic map each inlet coordinate points road conditions it is whether complete
Portion is unimpeded；Road to be evaluated described in the second electronic map is judged according to the real-time road of coordinate points each in the second electronic map
Whether the road conditions of the coordinate points of each inlet of mouth are all unimpeded；
First processing units further judge the first electronic map and the second electronics according to the judging result of third judging unit
In map, whether the road conditions of the coordinate points of each inlet at crossing to be evaluated described in any electronic map are all smooth
It is logical, if so, determining that the Signalized control at the crossing to be evaluated works well, and well it regard control effect as evaluation result
Initial time corresponding with the evaluation result, end time save after being associated with；
The second processing unit further judges the first electronic map and second when the judging result of first processing units is no
It is whether consistent to the display state of the road conditions of the coordinate points of each inlet at the crossing to be evaluated in electronic map, if one
Cause then determines that the Signalized control effect at the crossing to be evaluated is poor, and using control effect difference as evaluation result and the evaluation knot
It is saved after the corresponding initial time of fruit, end time association；
First prompt unit, according to each in the real-time road and the second electronic map of coordinate points each in the first electronic map
The real-time road of coordinate points judges that each of described crossing to be evaluated in the first electronic map and in the second electronic map enters
The whether all slow or congestions of the road conditions of the coordinate points of mouth, if then prompting the signal period at the crossing to be evaluated small.
5. the system according to claim 4 for realizing precisely evaluation semaphore control effect using internet, feature exist
In, further includes:
Second prompt unit, if the judging result of the first prompt unit be it is no, further judge the first electronic map neutralization the
The coordinate points shown in two electronic maps are slowly or whether the Way in of congestion is consistent, and it is slow that coordinate points are prompted if consistent
The split of slow or congestion Way in is small.
6. the system according to claim 4 or 5 for realizing precisely evaluation semaphore control effect using internet, feature
It is, the coordinate points indicate unimpeded when being green, indicate when the coordinate points are yellow slowly, when the coordinate points are red
Indicate congestion.
