Specific embodiment
Below with reference to accompanying drawings the embodiment of the outer suspicious figure's identifying system of intelligent car of the present invention is carried out in detail
Explanation.
Monolayer light bus: generally refer to size at 10 meters or less, the bus of handling capacity of passengers about 30 to 40 people.In
State medium-sized city is commonplace.In China's Mainland, people are usually used the abbreviation of mini-bus to call light bus；But Hong Kong is not
Medium-sized and coach are distinguished by, and the abbreviation of mini-bus is also generally used to call the China once doing big bus service in Xiang Gangying
Bus.Britain, the light bus of Japan are to refer generally to be about 10 meters, wealthy 2.3 meters, the monolayer bus of handling capacity of passengers about 30 to 50 people.
As Dan Nishi dartlike weapon bus, rich and powerful people's b6le bus and Hino rainbow etc..
Minibus: referred to as " minibus ".The common bus of volume ratio of general minibus is little, handling capacity of passengers typically 8 to
Between 20 people.Their majorities walk in that volume of passenger traffic is relatively low or route that need to service remote, curved many, road narrowly area.Some routes are also
Frequent order of classes or grades at school can be provided using little Palestine and Israel.In operation, the minibus of most area is not distinguished with common bus, example
As Macao, because the narrow car in Macao road is many, the curved position of wrong path is many and narrow simultaneously, and therefore to account for one in Macao's bus development history important for minibus
Seat.On the contrary in some cities such as Hong Kong, the operation system of public minibus is independently of outside common bus.In order to " minibus "
Difference, general bus also has and is referred to as " big bus ".
Fast public traffic system (bus rapid transit, abbreviation brt) is a kind of between rail rapid transit (rapid
Rail transit, abbreviation rrt) new public passenger transport Yu regular public traffic (normal bus transit, abbreviation nbt) between
System, is a kind of large conveying quantity mode of transportation, is generally also referred to as " subway system on ground " by people.It is using modernization public transport
Technology cooperation intelligent transportation and operation management, open up busway and build novel bus station, realize track traffic fortune
Battalion's service, reaches a kind of unique urban transit system of light rail excellent service standard.
