Now, link represents on road between node distance.In figure 3, section between node 311 and node 312 is called as link B, section between node 313 and node 312 is called as link G, and the section between node 313 and node 312 is called as link C, and the section between node 314 and node 312 is called as link E.
In addition, link-speeds represents when by a speed during link.Craspedodrome link-speeds represents the speed after by link B before link C, and left-hand bend link-speeds represents from the speed before link B to link E, and the speed of turning right represents from the speed before link B to link G.
Secondly, the method calculating the travel speed of each turn direction of crossing comprises: use the actual vehicle speed information in each section instead of weight to calculate the speed in each turning section.
[table 2]
Here, travel speed represents the speed in the section that adjacent two links are connected.As shown in table 2, left-hand bend travel speed represents the speed from link B to the section of link E, and craspedodrome travel speed represents the speed from link B to the section of link C, and travel speed of turning right represents the speed from link B to the section of link G.
Vehicle information center 200, based on the information of vehicles collected and the velocity ratio with reference section, calculates the position of each vehicle and the speed in each motion section.Such as, if (from link B to link E) travel speed is 60Km/s and is set to reference link assuming that turn left, then craspedodrome section (from link B to link C), become about 0.916 (55 (Km/s)/60 (Km/s)) with the velocity ratio of reference link, and right-hand bend section (from link B to link G), become about 0.966 with the velocity ratio of reference link.
Now, turn direction comprises multiple directions (left-hand bend such as occurred in three-way intersection, simple intersection or five tunnel crossings and right-hand bend).In addition, minimum speed by the vehicle of the respective stretch of crossing and maximal rate are measured to each travel speed, and calculates average velocity based on measured minimum speed and maximal rate.
3rd, each method calculating link-speeds of turning of crossing is comprised: the speed calculating a link.That is, described method comprises and carries out classification to the anticipated orientation passed through and carry out computing velocity.
[table 3]
As shown in table 3 and fig. 4, as the link-speeds of each turning, the speed of a link and the link-speeds of each turn direction are calculated.
Such as, the mean value of the minimum speed when turning left in link B and the measured and measured minimum speed of maximal rate and maximal rate is calculated, thus calculates the average velocity when turning left in link B.When the link-speeds of each turn direction uses such method to calculate, the average velocity turned left in link B is such as 62Km/s, and the average velocity of keeping straight in link B is such as 55Km/s and the average velocity of turning right in link B is such as 52Km/s.
When calculating the link-speeds of the overall link speed of crossing, the travel speed of each turn direction and each turn direction, control module 210 provides velocity information to road bootstrap module 240 and transport information bootstrap module 230 (S105), thus allows the velocity information calculated to be reflected in the transport information and route searching information being supplied to each vehicle.
Vehicle information center 200 is sending to each vehicle (S106) with reflecting as mentioned above the transport information of the turning information of crossing and route searching information wireless thereon.
Although illustrate the example of simple intersection in figures 3 and 4, the present invention also can be applied to the transport information at various crossing (such as three-way intersection or simple intersection) place.In addition, except the transport information of crossing, the present invention can also be applied to the access ramp (accessramp) of highway or the transport information at exit lane (outerroad) place.
As mentioned above, the present invention can provide the travel speed of each turn direction or link-speeds to provide the more accurate transport information wherein reflecting traffic turning information.In addition, the present invention can provide the travel speed of overall link speed together with each turn direction or link-speeds to provide the transport information of various crossing.Information of vehicles that the present invention can use each bar to collect calculates transport information and makes error range be minimized to generate and have high-quality traffic information data.
