Topic:
TRACC issue adding road network edited in ArcGIS

Hello,


Do you know if there are issues that can arise loading in a road network– Meridian based – after editing in ArcGIS? When I load the original set in toTRACC, all seems well – all features are loaded. However, after loading in toArcGIS and extending to include some extra cyclepath links, I cannot get theshapefile to load successfully. It reads fine and loads on to the road ribbonarea as an empty set of features with no error message.


In terms of my edit process, all I did was create a new shapefile anddigitise cyclepath links which snapped to the road network. Where thesecoincided with edges of the Meridian features, I split the feature to ensurejunctions coincided with end points of features only. To ensure the RoadLinkIDattribute remained unique, I suffixed ones resulting from split with ‘_X’ todifferentiate them from the original. I then merged the new cycle paths on tothe Meridian data and updated columns to match what looked correct. These toohad unique RoadLinkID assigned.


Is this a typical procedure, or should I only edit within TRACC itself?


I am planning now (time is against me) of doing within TRACC, but needto know if it is okay to plot a path which goes from edge to edge – i.e. notnecessarily to an edge point on the road network. It looks in thedocvumentation as if this is the case, with a screenshot showing such anexample and nothing to contradict this. It surprises me, but hopefully this isthe case as will be easier, I just want to make sure the underlying processingwill pick up the edge (road) to end (cyclepath) data.


Regards,
Graeme

We are pleased to announce our next public training course at Transport for Greater Manchester on the 13th October (1pm start) and 14th October (all day). This is a comprehensive course covering all the features and settings of TRACC. Basemap will provide one laptop per delegate and appropriate training materials. The course follows the agenda below: -

Session 1

Loading of road datasets and creating and exporting travel time contours

Session 2

Loading of public transport data and creating public transport contours and reports.

Looking at local accessibility access – showing distance away from PT stops and their frequency

Day Two – 9:30 arrival for 10am start (pastries coffee etc provided)

Session 1

Re-cap of Day1

Loading in Census Data and utilising the reporting power of demographics to show percentages of accessibility and which destination is the most accessible.

Session 2

Continue looking at demographic data along with other reporting options

Look at producing a public transport frequency map

Lunch (Provided)

Session 3

Look at the editing of the public transport network, using census data to look at the viability of a new TRAM route.

Session 4

Look at road editing, both the creation of new road links (footpaths etc) and look at the adjustment of speeds.

Re-cap and time for questions.

Finish about 4pm

To book please e-mail traccsupport @ Basemap.co.uk - the cost to attend is £550 + VAT for the 1.5 days.

Hi Michael,



The MCA file is the one that most resembles a CIF file, though be aware, there are many train positioning services included in their data - so be sure to remove these or the ghost trains will be included. Basemap offer this as a paid for dataset - http://www.basemap.co.uk/map-data/public-transport-data/




Kind Regards, Admin

Hi all



Has anyone managed to make use of the Timetable data provided by ATOC?


I'm trying to use it to produce rail accessibility plots in TRACC. Do I need to convert the .mca file to CIF before the timetable data can be read by TRACC?




Thanks

Michael

In order to Open the downloaded Meridian 2 or Census data (Shape Files) in MapInfo you need to use the Universal Translator to convert these to MapInfo Tab file first. You will not be able to use the File>Open option.

Just bringing this to your attention:-

What do you think about this new dataset? Great news it's going to be part of the PSMA and also a new OpenDataset to replace Merdiain2.

Somerset Stroke Service Review

In the spring of 2014, Somerset CCG set out to discover how a proposed centralised stroke service, based at Taunton Hospital, would affect the population of Somerset as a whole – a large county measuring 1,330 square miles and 70 miles across. Previously, the service review had assumed that a redesign involving the planned cessation of stroke services at Yeovil Hospital would offer the county’s patients clinical benefits, but a sophisticated analytical tool was needed to confirm this. Therefore the SWCS Geographical Information System (GIS) team was tasked with a systematic analysis of how the proposed changes would impact them.

Hi Alex



I see someone is dealing with this via our TRACC support email, so will let them support you.

I have managed to convert the data to OS1936 co-ord system . When importing into Visography it is coming up with the following error (something I imagine is an issue from the software I used to convert the data):


System.IO.FileNotFoundException: "The file specified does not exist."

Is that an issue with the convertor or Visography?

Thanks

I thought it would most likely be the co-ord system. I believe the data is currently in WGS84.

I do not have access to ArcGIS but may be able to change co-ordinate system with Spatial Manager a software which converts .osm to .shp files.

Any other suggestions?

Thanks
Alex
