Every road user relies on signs, so keeping them tip-top is in everyone’s interest. Now Transport Focus have launched their Sort My Sign campaign, asking road users to help them do just that.

They’d like everyone to report any signs they spot that are dangerous, dirty, broken, or obscured.

To support this programme digitally, Transport Focus came to mySociety, asking if we could help create a simple and intuitive mapping interface where these issues could be reported.

Keep your eyes on the road

Specifically, the scheme covers signs on roads managed by Highways England, which means motorways and some A roads.

FixMyStreet was the obvious starting point — we already have a data layer for these roads, which means that your everyday FixMyStreet reports can be routed to Highways England rather than the council if they are the responsible body.

Plus, as we’ve detailed many times before, the FixMyStreet platform can be repurposed for any project dealing with location-based reports, and has in the past been put to all sorts of uses, from reporting empty homes to helping fight corruption.

Nonetheless, we perceived one potential challenge when it came to setting up sign reporting.

Don’t report and drive!

FixMyStreet is generally well-suited for people making reports on the go — in fact, thanks to the ‘use my location’ functionality, it is ideal for reporting issues like potholes or broken pavements on your mobile while out on a walk. But obviously, road signs are a slightly different matter. If you are driving, you certainly mustn’t be fiddling with your mobile phone, so ‘use current location’ is only helpful if you have an amenable passenger to make the report.

That’s fine — you can always make the report later of course: but that means you’ll need to know roughly where you were when you saw the sign, something that’s a bit trickier on a long drive than it might be on a stroll around your neighbourhood. FixMyStreet allows you to find any UK location with the input of a postcode or street name, but these are details you’re unlikely to have to hand if you have simply driven through.

After some thought we realised that, on a motorway, the location identifier most people will find easiest to recall will probably be the junction number.

So that set us a challenge: how could we best enable ‘search by junction number’?

Sign here…and here

Ideally, we wanted a user to be able to visit the Sort My Sign site and enter the name of a junction, just as they’d enter a postcode or street on the FixMyStreet homepage — and then to be taken to a map centred on that point.

But sourcing a mapping between motorway/junction number and co-ordinates proved surprisingly tricky. mySociety developer Matthew takes over the story.

“I first looked at OpenStreetMap data — its geocoder, Nominatim, worked really well for some junction numbers, but didn’t work at all for others. If a junction has been assigned a name (like J23 on the M6, which is known as ‘Haydock’) it can only be looked up by that name, not by number. But we wanted users to be able to look up junctions by number.

“I could also export all the junction data from OpenStreetMap, but the junction nodes alone aren’t linked to the motorway, so that looked like it would prove tricky to match up.”

FOI to the rescue

“But by a stroke of luck, I then discovered that someone had used another of mySociety’s services, our Freedom of Information site WhatDoTheyKnow, to make a request to Highways England asking for the positions of all the driver location signs (the repeaters every 100m or 500m along the motorways giving the name and distance from start).

“In response, Highways England had provided that information, so I knew I could use that to at least provide a mapping between location sign and geographic co-ordinates.

“Each sign also had information about what junction it was nearest or between, so by constructing an average of all the location sign co-ordinates associated with a particular junction, I came up with a pretty good estimate for the location of the junction itself.

“I added all the sign and junction data into a small SQLite database (which means it’s portable and doesn’t need to be associated with the main database) and wrote a little bit of code to spot when someone entered a junction name in any of a variety of different formats, then look up the matching location in this database”.

Signed, sealed, delivered

To test this out, Matthew had all his colleagues name their favourite junction… perhaps not to be recommended as a party game, but it did at least prove that his code had cracked the problem.

Something much appreciated by Head of Strategy at Transport Focus, Guy Dangerfield, who says, “mySociety has been excellent in understanding what we needed and finding ways to achieve our objectives.”

You can give the new system a go here — and perhaps bookmark the site so that you know where to report a sign next time you see one that needs fixing.

Once you’re safely off the road, that is.

We’re back at the big highways maintenance expo of the year, Highways UK on 6-7 November, in Birmingham’s NEC.

If you’re attending and you’d like to know more about FixMyStreet Pro, come and seek us out at stand I23, where we’ll have brochures for you to take away.

Stay for a chat with David and the rest of the team, who will be delighted to discuss everything from CMS integration to the display of assets, to how we’ve made life easier for your staff behind the scenes. Best of all, ask them about the savings you can make when you install FixMyStreet Pro as your main reports interface.

But don’t just take it from us. Anna Fitzgerald from Oxfordshire County Council will be joining us all day on the 6th, while Rob Gillespie from Ringway, who are responsible for the Isle of Wight’s Island Roads and Hounslow’s highways, will be available for a chat from 2-3pm on the 7th.

Here’s where to find the FixMyStreet stand: we’re looking forward to seeing you there.

It’s something we’ve been wanting for a long time, and it’ll very soon be a reality: FixMyStreet reports will, where appropriate, be channeled to Highways England. Look out for this functionality in the coming week.

My way or the highway

Previously, if you reported a problem on one of the country’s motorways or major A roads, we had no way of identifying whether it was the responsibility of the government department rather than the council. We had to rely on whichever council the report fell within, and hope that they would forward it on.

But now, we can send reports off to just the right authority. What’s changed to make this improvement possible?

Well, FixMyStreet uses our MapIt software, which matches points (in this case, the pin you put in the map when you make a report) with the boundaries they fall within (mainly, until now, council boundaries). That’s how it knows which council to send your issue to, even if you have no idea yourself when you make the report.

Motorways and A roads have boundaries too, of course, but that data wasn’t previously available under an open licence that would allow us to use it on the site. That all changed with GOV.UK’s release of the Highways England Pavement Management System Network Layer — just what we needed!

So now, if you make a report that falls within a small distance from one of the relevant roads, FixMyStreet will use MapIt in combination with this data layer. You’ll see a message asking for confirmation that your report actually does pertain to the highway: where roads cross a motorway, for example, a pin could relate to the road on a bridge, or the motorway below.

Confirm either way and boom: off it goes to either Highways England or to the council, as appropriate.

So that’s a big thumbs up for open data: thanks, GOV.UK! It’s also a good example of how our commercial work, providing FixMyStreet Pro to councils as their default street reporting system, has a knock-on benefit across the open source FixMyStreet codebase that runs not only FixMyStreet.com, but sites run by other folk around the world.

As you may remember, we recently added red routes to Bromley for FixMyStreet Pro, and it was this bit of coding that paved the way for the highways work. We can only prioritise not-for-profit development if we have the funding for it; but being able to improve FixMyStreet for everyone on the back of work done for commercial clients is a win for everyone.

Or, as our developer Struan says, in a metaphor perhaps better suited to shipping routes than highways, “a rising tide raises all boats”.
