All suppliers are asked to include in their software additional data checks over and above those checked for in the NaPTAN schema. The latest checks are listed in version 1a.
Some systems move the DEL records to an archive or allow them to be hidden so that they are out of the way of current processing and cannot be used in error. On the NapTAN viewer DEL records are marked by an X symbol
In NaPTAN a bus stop can be put temporarily out of use between certain dates.
There is some discussion of creating a list, outside NaPTAN, of stops that have no services using them, so that they can be hidden on mapping or enquiry systems.
If a bus stop has been deleted it can be made active again by changing the Record Status from DEL to ACT.
A stop with Record Status PEN is one that has not been submitted by the local authority in more recent uploads and has been restored from previous records. All stops like this need to be attended to by the local authority and made part of their regular submission, probably with Record Status DEL.
A bus operator or local authority contracting department may request a new stop. It is best to provisionally agree as precise coordinates as possible and allocate an ATCO Number in the local authority's numbering scheme. NaPTAN2 has some facilities for putting a bus stop temporarily out of use and it may be possible to use this to ensure that the bus stop does not display on maps while the consultation process to locate the stop proceeds.
ATCO Numbers are composed of three parts:
The ITO naptan tool includes various tests to help improve naming.
Locality Name, formerly called NatGazLocality is a good place to start. There is a bit of an art to choosing the right locality. Usually you will choose the nearest one. However the road network and local geography may indicate that you choose the next nearest. However you should always avoid leap frogging a locality as this will cause confusion. You may need to set up a new locality Name. The ITO naptan tool includes various facilities to view the shape of localities and tests to help identify overlaps and inconsistencies.
The LocalityCentre flag (set to Y or N) can be used to denote whether the stop, perhaps with one or more others, should be regarded as the centre of the locality. In the ITO naptan tool these stops are marked with a dark purple band.
Short Common Name This is a new field in NaPTAN2 but is good for concentrates the mind. How short is a length that you determine locally dependant on your infrastructure. However some ticketing systems look for a name of no more than 15 characters. This can include abbreviations and it may be appropriate to include the locality name or part of it.
Common Name Having got the Short Common Name and Locality you can identify a Common Name which should still short but not as constrained as the Short Common Name. It should also be suitable to be presented as Locality+Common Name so should not normally include the Locality name. Very mundane names such as Cross Roads, or letter box may be ok because they can be associated with the Locality Name and within the locality are a known point.
The advice is to try and avoid street names, especially the names of long streets. (Here the advice comes into conflict with naming conventions that have deliberately chosen street names because they change less frequently than landmarks). If a street name is to be used it should preferably be that of a cross street or a short street that the bus stops are located on.
Indicator formerly called Identifier, is used to describe the stop more precisely in relation to the Common Name. It should be kept as short as possible. It can be used in some the following ways:
See further Guidance on Preferred Indicators.
The direction should be the orientation of the road at the bus stop itself whatever the general direction of the bus service. So if a bus is generally moving in a northerly direction it may, due to corners in the road network, use a stop with direction code S. The ITO naptan tool now includes a test of the bearing against the direction of the road on Navteq maps.
A Stop Type BCQ is suitable where the stand allocation may be variable. It may be particularly useful for coding bus arrivals. The exact location of this should probably be near the vehicle entrance to the bus station and possibly separate BCQ stops for each vehicle entrance. This way real time systems can detect that the bus has arrived in the bus station even if it has not gone to the allocated stand.
