Description
Technical field
The present invention relates to a kind of electronic chart road name display packing, especially relate to the several display packing of a kind of electronic chart one tunnel.
Background technology
Along with Global Positioning System (GPS) (Global Position System; GPS) technology is perfect day by day; Portable terminal in conjunction with accurate digital navigation map; Can realize that (Current Car Position, (Point of Interest, inquiry POI) reaches carries out route planning and voice dynamic guiding to the result who searches out to accurate location, address information and point of interest CCP) to current parking stall.The convenience of real-time navigation in driving procedure; The fast development and the application of navigation consumer electronics series products have been caused; Like Portable Automatic navigational system (Portable Navigation Devices; PND), mobile phone navigation, vehicle mounted guidance etc., also greatly improved the network electronic map inquiry simultaneously and used, promoted everybody understanding to electronic map application.
Electronic map application is broadly divided into online network inquiry of PC version and off-line type portable terminal navigation application two big classes, and the former is applied as the master with office with the house; The latter is with PND, and move modes such as mobile phone navigation and vehicle mounted guidance are main.
Electronic chart progressively becomes the part of people in modern life, wherein the demonstration of road name and to be applied in the electronic map application be basis and aspect the most intuitively.Especially in the vehicle mounted guidance field, " demonstration " of road name reaches " application " two functions and has influence on directly that the user experiences satisfaction and information is obtained abundance, and in actual life, a road possibly have a plurality of link name simultaneously.Especially road net title in the city scope at first has a town road name (generally appearing with the guideboard form); This town road may exist with national road net form in Ministry of Communications's railway network planning simultaneously; Be defined as national highway; Provincial highway; County, township's accommodation road, road, village and other highways (this type of road name representes that with numerical coding generally imprinting embodies on stone tablet, also can on guideboard, embody in some city).
National highway is meant that public backbones is called for short, and generally is to represent like " G308 " (or " three bit digital+national highway " are like " 207 national highway ") with " G+ three bit digital ".
Provincial highway is meant in Ben Sheng (autonomous region, municipality directly under the Central Government) politics, economic field existence and is significant; Connect key city inside the province with main economic zone but do not belong to the important highway of national highway, generally represent like " S357 " (or " three bit digital+provincial highway " are like " 254 provincial highway ") with " S+ three bit digital ".
Counties and townships' accommodation road, road, village and other highways are generally represented with X/Y/Z/Q/C/001 to X/Y/Z/Q/C/999.
Have bridge again if these have in the highway section of two link name, bridge place road has a bridge name again, and then can there be three link name simultaneously in this section road.
In simple terms, in real road, may there be town road name (guideboard demonstration) simultaneously in a road, digital link name (demonstration of road upright stone tablet) and bridge name.
The electronic map road name receives size restrictions when navascreen shows, the displaying scheme of link name directly has influence on obtaining of client's use experience and information, especially has two or when above when the name of one section road.The link name displaying scheme that navigates on the market has nothing in common with each other, but some incomplete aspects are always arranged, and comparison information is following in detail.
Scheme (1): town road name and digital link name Alternation Display (be usually used in the inquiry of PC version network map and use, the displaying scheme that partly navigates is also selected for use)
Presentation mode: town road name and digital link name are intersected and are shown
Shortcoming: just can see the road name clearly when map displaying ratio chi must be adjusted to greatly, navascreen displayed map scope is less under this engineer's scale, usually only can see in current screen that digital link name shows on road.When having only digital link name to show, let the user that current C CP position is produced easily and query.Because the town road name shows on guideboard that all the user exchanges custom usually and adopts the town road name, digital link name seldom is used or not knows.Let the user produce suddenly the illusion of taking a wrong way when only showing this section road easily and have influence on driving with digital road famous-brand clock.This situation is particularly strong to the customer responsiveness that sails strange urban road into, because on guideboard, usually only can see the town road name.
Scheme (2): town road name and digital link name show simultaneously
Presentation mode: both occur synchronously
Shortcoming: this mode can make and show that link name is long, produces the demonstration collision with interface display POI title and hides side's information, causes interface display information to reduce.
Scheme (3): town road name and digital link name show under the different proportion chi
Presentation mode: display digit link name during large scale shows town road name (perhaps displaying contents is exchanged) during small scale
Shortcoming: when engineer's scale is regulated, target road name generation conversion, the user is difficult to confirm target road.
Scheme (4): only show the town road name, but " digital link name " can't be participated in the road search
Presentation mode: the road of two names of exist actually (town road name and digital link name), link name only shows the town road name on electronic chart
Shortcoming: can't also can't carry out " digital link name " destination or intersection road and select and route planning through navigation road list query " digital link name ".
Scheme (5): in above-mentioned four schemes, the bridge name does not show at map interface
Presentation mode: the bridge name map interface do not show or with the last period road name show at map interface as this section bridge title
Shortcoming: bridge is as landmark in the actual life, and the information interchange of Chang Zuowei appointed position is used, and this title does not show in electronic map interface, can bring the not convenient property of some uses to the user.Some navigation engine scheme can't can not directly be directed to this position as the destination programme path simultaneously through search index to the bridge name.
The existing 5 kinds of schemes in above-mentioned market are not all handled one tunnel several demonstration problem well, and market is anxious expects a kind of a road outstanding several display techniques.
