NPTDR 2012 Hi MJ,




Ok the first check is to make sure the XSLellentValidator.dll is in the program files/accession folder. If not you can get this file from the following thread: -




http://forum.basemap.co.uk/topic118-xslellentvalidatordll-missing.aspx




If you have the file, then you might need to register the DLL, For XML validator registration, since it is .NET dll, it requires .NET 2.0 runtime installed. To manually register the dll, using the following steps:

1.Navigate to C:\WINDOWS\Microsoft.NET\Framework, there should be a directory with a name such as “v2.0.X”, where X is some minor version number (such as 50727) , if this directory does not exist, you need to install .NET 2.0 runtime (download it from Microsoft website)

2.Start command prompt, if you are running Vista, you need to run it as Administrator

3.Navigate to Accession install directory (C:\Program Files\Accession), where you should find XSLellentValidator.dll, type the following command:




C:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm XSLellentValidator.dll ; remember 50727 is the minor version number, depending on the version of .NET 2.0 runtime installed, this number may be different on different machines.




This should then solve this issue.




Finally to address the last point, the data is only available in Traveline regions. The traveline site gives an indication of where these are. (http://traveline.info)

NPTDR 2012 Peter,



Would you say the NPTDR is important for the work you do? We spoke with the DfT and they were interested in talking to public sector bodies who might still have use for the NPTDR...

NPTDR 2012 The ATOC Rail data is a funny one, the pseudo CIF file that's produced can not be read in Accession. It will require someone manually converting each line into a valid CIF file format - we will look to potentially write a converter/importer in the future. The main issue is that this file is national, therefore will have a detrimental affect on the performance speed. Also the TNDS is only avaialble by TL region, so you either have to do a windows search in the files like MJ explained earlier, or import the lot.

NPTDR 2012 Hi Rowley,



That is concerning, what date of data are you using? What is the service number that's showing the issue highlighted?




Cheers,

NPTDR 2012 Hi Pete,
We can understand your frustration; we're currently working on a solution to the NPTDR. Unfortunately this would be a paid for service, however we're looking at taking the TNDS data and splitting it into smaller regions like the NPTDR, along with bringing across the ATOC rail data. We hope to release this dataset either twice a year or quarterly on the same date range each year - this should then allow people to do comparative studies using the data. The cost will be small; we're looking at either a £50 + VAT one off download cost, or a £250 + VAT annual subscription to the datasets. The data would be provided as a CIF file only.

I would have to stress, only limited checks would be done on the data - though having looked at the NPTDR - it seems there were little checks done on this dataset.

What are people’s thoughts on this?

NPTDR 2012 Hi,



The prices quoted are for the full GB dataset, we are working with Northern Ireland about making their data available to.




You will be able to load the full TNDS TXC datasets into any new software, however this will be for a Traveline Region, so all of Scotland for example. We aim to offer broken down chunks of CIF data per country, and release a dataset every quarter to allow easy comparisons of data.

Road Type - Definition We often get asked what defines a different road type, well the answer is below: -

Motorway
A multi-carriageway public road connecting important cities, always numbered and with no addresses.
A Road
A public road, classified as an A road by the DfT, connecting areas of regional importance, always numbered, sometimes named, often with addresses.
B Road
A public road, classified as a B road by the DfT, connecting places of local significance, always numbered, sometimes named, often with addresses.
Minor Road
A public road without a DfT classification of motorway, A or B that connects the roads defined below to B and higher classification roads*.
In urban areas usually named, often with addresses. In rural areas sometimes named and sometimes with addresses.
Local Street
A public road that provides access to land and/or houses, usually named with addresses. Generally not intended for through traffic*.
Alley
A road without access restrictions that provides alternate/secondary vehicular access to land or houses. They may be named but are usually without addresses. They are usually not intended for through traffic, though they may be accessible from more than one location.
Typical examples are those that run behind rows of houses.
Currently, coverage is limited to roads formerly described as ‘Private’ in previous Ordnance Survey road products but reclassified following ground visits.
Private road – publicly accessible
A privately-maintained road or a road within a property boundary where publicly access by the public is considered usual for at least some part of the day. For example, a road within a hospital, sports centre or school.
They may extend through a site if more than one entrance exists. If only one entrance exists they are normally created to extend to the principal building within a single site or the boundary of the last property served for features accessing more than one addressed or otherwise identifiable property*.
They may be captured outside this definition if required to provide restricted connectivity to a track or path.
Private road – restricted access
A privately maintained road or a road within a property boundary where access by the public is restricted by physical (for example, gate) or administrative (for example, sign) means or is not considered usual. For example, roads within a military base, an oil refinery, within a private residential garden or leading to two private properties*.
Such roads are captured only where they exceed 100 m in length or serve more than one addressed or otherwise identifiably separate property.
Roads are normally created to extend to the principal building within a single site or the boundary of the last property served for roads serving multiple properties. Two exceptions to this exist:
where a track or path exists that the road is connected to, the road must be extended to that pointwhere roads within a private residential garden extend for more than 100 m from the property boundary
Pedestrianised street
Roads that have been altered for use principally by pedestrians but may street provide some access for certain types of vehicle*.
Details of specific routing access restrictions will be within the RRI theme.

New NPTDR Dataset I trust you’re all keeping well, we’ve just released a dataset that we think will be of interest to the group. We have decided to replicate a basic version of previous years NPTDR data, the NPTDR database historically contained a snapshot of every public transport journey in Great Britain for a selected week in October each year. After October 2011, it was decided to no longer renew this dataset as it has been replaced by the Traveline National Data Set (TNDS). This is transport data available for each Traveline Region and made available as TransXchange XML files. Our clients have had issues loading these large datasets into Accession, due to the stops (NAPTAN) data only being available nationally and each region covering a large area - sometimes requiring thousands of files to be checked against the online schema.

From client feedback, Basemap have reproduced a limited version of the NPTDR. This will be a copy of the raw TNDS data relying on the checks done by each Traveline region, this contains mainly bus information, but in some areas there are additional datasets - such as London where Tube, Ferry, Cable Car and Tram are included.

The rail data will be sourced directly from the association of train operating companies (ATOC); this will then be converted into a CIF file. No checks will be made against the data; it will be assumed the timetables are correct.

Basemap will then split both datasets into smaller areas, with the data being provided as one CIF file per travel mode per area - this will also contain the relevant NAPTAN stops in the file footer enabling only one file to be imported per area, per mode.

We will provide a feed of the National Coach data, this however will not currently be split up into smaller areas, but will be available as a complete CIF file (with stops included).

Access to this data will be provided through an FTP subscription service, with updates given every 3 months from launch July 2013, these will be done to reflect a weeks’ worth of data on the following dates: -

• 2nd Week of January
• 2nd Week of April
• 2nd Week of July
• 2nd Week of October (Original NPTDR date)

The annual subscription cost per company/FTP access account will be: -

• £250 + VAT for access to all data.
• £200 + VAT for access to the bus data only.
• £100 + VAT for access to the rail data only.

If you think this dataset would be of interest to you, please feel free to get in contact.

Review of the national accessibility statistics The DfT are currently reviewing the importance of national accessibility statistics. Don't miss your chance to suggests what statistics you might need in the future, along with the opportunity to request other new datasets..



The survey is at https://www.surveymonkey.com/s/PVTDCXN

Speeds for Local Authority Managed A-Roads We quite often get asked about what speeds should be used in accessibility software, after a recent exchange of e-mails with the Department for Transport they pointed us to the following link. We thought it useful to share this information.

Running out of memory Hi Ian,



Eeek, that's no good. Seems like you might require the 64 bit version of TRACC. Please may I ask what version of Office you have installed?

Running out of memory Hi Ian,



Ahh that's a pickle, to run the 64 bit version of TRACC you would require a 64bit OS as well as a 64 bit version of Office. The reason you got the out of memory exception is due to the RAM limitation being met on a 32bit machine. Are you able to load less ITN and UP tiles in the short term to test?




Regards,

Loss of functionality Hi Ian,



Just to clarify, if you selected a 400m cut off - this will always be the actual distance, this relates to governmental guidelines that used to be released - the walk factor is then only added afterwards to generate the journey time - but will never affect the distance.

Running out of memory Hi Ian,



I just wanted to clarify on your response, we are looking into the use of multi-threading - this will provide an significant increase in the calculation time.




We are not going to look to do a different algorithm though, the main reason for this is that we have always tried to sell TRACC as a more accurate way of calculating travel times, but lessening the detail of the algorithm - in our opinion make the results less useful. We are going to focus on improving the existing algorithm by using different methodologies to manage the underlying data, which will then allow the current algorithm to run faster. I trust this makes sense?

Accurate Results?! Hi All, I have been watching this thread with interest - so what do you think we should do with regard to Interchange Penalties?

Cycle routing wrong way on one-way links Hi Ian,



It was decided to only utilise the turn restrictions and one way links for the car drivetime accessibility calculator, though I think perhaps giving this as an option to the user is a good idea for the future...

Unable to load postcode data - no OSCodepoint? Hi Andy,



Ahh yes, you will need to load/install the Geo-Coder manually, this can be done via

TRACC Geo-Coder and Help File If you want to utilise the Geo-Coder, you will need to install this from the following link. This will be updated every year to represent the changes made in CodePoint data, if you utilise this you'll need to add the appropriate copyright from Ordnance Survey - these can be found on the top of the page here.


Secondly, if you want to download the free help file for TRACC, please feel free to do this from the following PDF link.
