About Me Hi,

My name is Rowley and I work for Staffordshire County Council, and have been using Accession for around a year and a half now (as I think Dan probably knows by now from my many e-mails in the past!), mostly for calculating national indicators such as access to certain hospitals in Staffs by bus, so I do a lot of exporting of contours to Shape File for analysis, as well as using it to assess options for new bus services. My work often includes creating new bus services within Accession, as well as modifying existing routes to test different scenarios. I use CIF files downloaded from Traveline when required as I have looked at the national download of CIF files for Staffordshire and it does contain a number of duplications and omissions so is not accurate enough for my needs.

I will be very interested to know of issues which other users have experienced with using Accession to see if they match the experiences I have had with it over the last 18 months.

Cheers,

Rowley

CIF Data I believe the REF file contains all the bus stop names used within the Bus file. I have used a Bus file but didn't intially use the REF file, until it was obvious that all the stops imported had no names. I re-imported the bus file and the REF file and all the stop names were included. If you use the overwrite function when importing the REF file it does overwrite any names of existing stops in your network.

Hope that helps,

Mastermap ITN Data Hello,

I have an issue with new Mastermap ITN Data, do you know how to import the new 'layer' format Mastermap data into Accession, as ITN now has 15 separate components. Previously, it was just a .gz file I believe but now it appears as multiple sections.

Thanks,

Rowley

Mastermap ITN Data Just realised the .gz file is still there so not actually a problem.

Mastermap ITN Data Haven't come across a GML file before, only seldom use the GZ files to be honest, but never had any issues with loading them in.
Thanks,

Traveline National Dataset (TNDS) Hello,

Have got a download of the data for the West Midlands as I am having a look at how this could be used in Accession, but get an error message when I try to select files for Download stating 'Error Creating the XML Validator, please make sure that you have installed .NET 2.0 runtime & the XSLellentValidator.dll is in the exe folder'. I appear to have a file on the C:/ drive with the name XSLellentValidator.dll already there and have .NET 2.0 framework on my computer but the TransXchange file will not open. Is .NET 2.0 runtime a different program? Any ideas?

Thanks,

Rowley

Traveline National Dataset (TNDS) I have tried typing that command in the C:\Program Files\Accession directory but just get an error message (says the file is not recognised as an internal or external command, operable program or batch file). It appears I have all the relevant files, there is a v2.0.50727 directory on my C Drive in the Microsoft.NET\Framework folder.

Traveline National Dataset (TNDS) I don't, which might explain the problem.

Traveline National Dataset (TNDS) Hello,

I have had a further look at this now, turns out I don't need admin rights as I had missed out something from text in the command prompt. I have now been able to choose the TXC files I wish to import which I couldn't do before, but am now getting a new error when I try to import them. The error in the log is coming back as saying 'some xml files are invalid according to the schema'. When opening up one of the .csv validation files the error stated is 'The http://www.w3.org/XML/1998/namespace:lang' attribute is not declared. Seems like there is something missing perhaps from the xml files, or that there is something missing from the schema?

Thanks,

Traveline National Dataset (TNDS) Our IT guys have amended a setting on my computer regarding authentification via a Proxy server (turned it off I think) and I can now import the TNDS .xml files, not entirely sure what they have done and it kind of breaks our usual internet protocol from what he was saying but can now import the files. Or IT guys have asked is it possible to tell Accession in any way not to use the computer's proxy settings?

NPTDR 2012 Hi all,

I have given up trying to use the TNDS file, after much fiddling by our IT guys to open up all the relevant firewalls on my computer so I could actually load in TXC files, the process is so labourious with having to upload Naptan data first (and for our county, we have to load in all adjacent authority data as well, and one of these is Centro so that takes forever), after 10 sets of Naptan data have been loaded I have kind of given up. If I only load in Naptan stops for our authoritiy it seems to miss out stops near the boundaries. I still haven't been able to replicate what I have been able to do using CIF files. I used to be able to download out of Traveline up to date CIF data for any service in the West Midlands, but from June 1st the new version of Traveline came on line and we have not been able to do this. So, if I am doing any Accession calculations for a specific area I am having to use a June 2012 network and update all the relevant timetables in that area it if any network changes have taken place, so we now have a number of route networks flaoting around, some with Stafford changes for 2013, some with Tamworth changes from Oct 2012 etc.

I have never used the NPTDR file as it will only be up to date for a very short space of time, and if you are doing a calculation relevant to a new development then it really needs to be up to date, but at least it was CIF format. The rail file was very useful, although national, but could have been a bit easier to navigate through, unless you know rail headcodes for each journey of a service it could take forever to isolate a journey or service that needed amending.

NPTDR 2012 Hi all,

I have a few issues with TNDS data, which I have now finally managed to get into Accession, but some of the information is missing which is causing problems with trying to run a calculation. Within the timetables for each service imported, for certain services the Vehicle Type, start/end date and operating days are missing, and each journey in the timetable is suspended. This has occurred for all services coded by Staffordshire on Traveline (and Stoke-on-Trent and other West Mids authorities except Centro) but those coded by Centro do include a Vehicle type and Days of Operation (but not start/end date) and each journey is not suspended.

What is also clear in the TNDS data is that some journeys in the timetable have incorrect running times, the journeys exist and the start time is correct but the intermediate times are too quick. I have one peak hour journey on an interurban route into Stafford that in the TNDS data appears to arrive 11 minutes earlier than actually timetabled. This particular journey is 8 mins too early at the previous timing point, then 5 mins too early at the one before that. The correct times appear on Traveline however. I have looked at a couple of Stoke-on-Trent services which also appear to be 10-15 mins too fast compared to the timetabled journey time.

Any suggestions?

Thanks,

Rowley

NPTDR 2012 Hello,

The TNDS data set I was using for Staffordshire was from 15th January 2013, so not totally up to date but that was the most recent set we had already downloaded. All timetables beginning with the prefix twm_ have journeys suspended in the timetables when imported. Timetables with a twm_ prefix are those coded into Traveline by the West Mids shire authorities such as Staffs, Worcs, Warks and Stoke-on-Trent. Those timetables with a cen_ prefix are coded into Traveline by Centro and these import in with a vehicle type and days of operation.

I have just looked at 2 services so far in Accession in terms of journey times compared to timetabled journeys times, service 825 (Staffs service) and service 101 (Stoke service). Will be having a look at a Centro coded service (110) to see whether the journey time problem is affecting these services as well.

Thanks,

Rowley

Accurate Results?! Hi all,

The interchange penalty is an interesting debate, and I have not fully got my head round how this is affecting output. One thing I have noticed which I need to fully understand is how TRACC is taking account of services where there is a big loop at one end of the route. For example, in Stafford we have a number of town services that do a large loop of an estate at one end of the route - in reality passengers can board or alight on any part of the loop to go into the town centre. But I have noticed one part of the loop has access within 30 minutes and the other part of the loop has access within 60 minutes. In reality it is the same bus and the whole loop should be within 30 minutes. But, the CIF file is split out in 2 parts (an inbound and an outbound journey - how it is coded on Traveline), with the terminal point being part way round the loop. I haven't checked this but will get round to it but I suspect that because the interchange penalty has been set at 5 minutes TRACC thinks that the passenger alights from bus at the end of the journey and then waits 30 minutes for the next service as it thinks its a new service. If the CIF file has been coded as a whole loop then I suspect this issue won't occur, but that is down to whoever codes the service into Traveline which we have no control over.

I will try the same calculation again with a 0 min interchange penalty and see if this solves the problem. This could however create a number of other problems elsewhere.

Regards,

Rowley

Accurate Results?! Hi Ian,

That would be the ideal situation, although how easy that is to create I have no idea. Just doing a test now actually, recoded the two parts of the service as one continual loop to see if I get a better result. Luckily this service only has around 20 stops all told and a simple 30 min frequency, anything more than this would just not be possible! It was somthing that just immediately jumped out at me in the contour, don't remember having this issue with this particular estate previously.

Rowley

Accurate Results?! When I run the calculaton with the service recoded into one continuous loop it does gives me access for the whole estate for 21-30 minutes, still with a 5 minute interchange penalty.

As suspected, if I run the calculation with the interchange penalty set at 0 mins and the original timetable with the service split into two parts included then the whole of the estate comes out with access between 21-30 minutes as well.

Global Edit of road links Hello,

I have just tried to amend a couple of roads speeds using the Global Edit function but if I reopen the file it just shows the old values, it doesn't save the amendments made.

Rowley

Global Edit of road links Hello,

In the Global Editing box - if I open that up and change a road speed. If I open the box up again the road speed hasn't changed, just shows what it was before. I just want to amend all A and B road speeds for a road network. Doesn't seem to be any way of saving changes that have been made.

Regards,

Rowley

Global Edit of road links Hi,

The road speed has updated when I open up an A road separately.

Rowley
4/24/2014 3:56:51 PM
Global Edit of road links I think that might be a good idea - I hadn't thought about checking an individual link, I just assumed it hadn't worked as the figure in the box didn't change.
