Over 2,000 road crashes outside schools spark calls for 20mph speed limit

This Detail Data map contains details on the number of road traffic collisions leading to injuries that occurred within a 100m area around each school in Northern Ireland, occurring on weekdays 2005-2014. Zoom in on the map to view individual school sites. The crash data was obtained from the PSNI and the geographic data was obtained from the Department of Education. Where a collision occurred within 100m of more than one school they are mapped to each but are only counted once in the overall figures. The circles represent the 100m radius surrounding each school in Northern Ireland. The colour of the circles relates to the number of road traffic collisions that occurred close to each school. The data relating to school location is based on the addresses recorded by the department for the 2014/15 school year.

ELEVEN people - including one child - have been killed and over 2,600 people have been injured as a result of road traffic collisions close to schools in Northern Ireland over the last decade.

Of the non-fatal casualties, over 200 had injuries considered ‘serious’. The remaining were recorded as ‘slight injuries’.

Using PSNI statistics, Detail Data has mapped every road traffic collision (RTC) resulting in an injury close to a school over ten years. We only examined collisions which occurred on weekdays within one hundred metres of a school, between 2005 and 2014. There were 1,766 collisions in total.

Our findings have led to calls for part-time 20mph speed limits outside schools across Northern Ireland, similar to those in operation across Scotland where they have been installed at almost all schools.

Detail Data’s investigation has shown that almost one fifth (18%) of those injured close to schools were aged 16 or under, a higher rate for this age group when compared to collisions regardless of location (11.9%).

The Department of Infrastructure was unable to confirm how many schools across Northern Ireland are located next to 60mph roads. However, our analysis found 78 schools where collisions had occurred nearby on 60mph roads.

A Stormont study from 2014 found that while there were a number of engineering measures which could be introduced to create safer roads around schools, part-time 20mph speed limits were the most effective system.

Including pre-school, primary, post-primary and special schools there are over 1,500 schools in Northern Ireland. However only three schools currently have part-time temporary 20mph speed limits and a further three schools are earmarked to have these measures put in place.

Electronic flashing signs at the beginning and end of the school day are used to highlight the change of speed to 20mph and legislation is required for police to enforce the speed limit.

The Department of Infrastructure said while it prioritised sites most in need by looking at traffic volume and vehicle speeds, it estimated that the cost of implementing these measures ranged from £40,000 to £50,000 per site. This includes the power supply connection and cost of engineering works.

We have spoken to two principals whose primary schools are both situated on 60mph roads. Despite the fact that they are located in the same county, only one of the schools is currently in the process of getting part-time 20mph speed reduction measures put in place.

In a statement to Detail Data the Department of Infrastructure said the safety of children on their journey to and from school is of the highest priority to its Minister Chris Hazzard.

A spokeswoman said that a number of other measures could be put in place to make roads outside schools safer such as enhanced road markings and lay-bys.

Commenting on the use of part time 20mph speed limits she added: “It is worth noting that in other countries where default 20 mph or 30 kph speed limits outside schools have been adopted, research reports note that, unless it is aggressively backed up with police enforcement, these reduced speed limits quickly fall into disrepute by drivers.

“Especially when they see no activity outside schools and traffic speeds revert to what drivers consider as a safe speed. The key success of part time limits is that they cover a short distance and drivers can clearly see that there are children present.”

Responding to Detail Data’s findings, PSNI Road Policing Inspector Rosemary Leech said: “We are happy to participate in the process that attempts to prioritise applications and sites that have been identified as being suitable for such a scheme. The widespread roll-out of such schemes places a significant enforcement burden upon police.

“If this were to happen, each site would either need to be prioritised for police enforcement or designed to have a remote camera detection capability. The necessity for a 20mph speed limit at any given location needs to be obvious to the motorist, with the result that drivers will generally respond in a positive manner.”

Inspector Leech added that police take a number of steps to ensure greater road safety at schools: “We respond to requests for enforcement of speed which involve school crossings and school keep clear zones.

“The NI Road Safety Partnership also delivers an enforcement capability in response to community concerns. The PSNI will also visit the site of all fatal or serious collisions in conjunction with Transport NI to determine if an engineering solution is a viable option at the location. PSNI also participate in the assessment process for suitability of school part-time 20mph limits or other engineering measures.”


Our interactive map was created using PSNI road traffic collision statistics collected between 2005-2014 and Department of Education co-ordinates for every school in Northern Ireland, from pre-school through to post-primary. The data relating to school location is based on the addresses recorded by the department for the 2014/15 school year.

Detail Data created a catchment area on the map for each school to capture and analyse road traffic collisions that occurred within a 100m radius of each school site.

The data relates specifically to collisions that occurred Monday to Friday at any time of the day. This will include incidents outside of normal school hours as well as during holiday time, but excludes those that occurred on Saturday and Sunday.

The police data does not cover collisions which resulted in no injury. It is not possible to tell whether or not those injured in a collision have any connection to the nearby school.

We analysed 1,580 schools across Northern Ireland. 596 had at least one RTC which caused an injury within 100m of the school site during a weekday in the ten year period.

The number of RTCs may be higher for some schools located close to major junctions or main thoroughfares.

For example St Mary’s Primary School on Divis Street in Belfast is located near to the Westlink. Approximately 13 of the 36 RTCs within the 100m radius of this school appear to have occurred on the dual carriageway or on the slip road leaving the dual carriageway.

The data shows that during this period there were 1,766 weekday collisions resulting in 2,660 casualties. Of those injured 479 (18%) were aged 16 and under.

Of the eleven deaths recorded one person was aged 10-16.

The most common time for RTCs near schools was between 3pm-4pm (10%) followed by 8am-9am (8.9%).

Between 2003 and 2006, the Scottish Government provided funding and specific authorisations to local authorities to introduce part-time 20 mph speed limits around schools. The initiative saw the vast majority of local authorities put these in place around all their schools.

However Rod King from the UK-wide campaign group 20’s Plenty believes temporary speed limits outside schools only partially addressed the issue of speeding on roads.

He said: “Whilst there may be a case for making some 20mph limits temporary outside schools which are on main roads, this does not solve the problem of vehicle speeds being too high across the community.

“We need to change the whole mentality from driving at 30mph and just slowing down in a few places to one where we accept that 20 is plenty where people live, work, play and learn and only go faster where safe and appropriate facilities exist for vulnerable road users wishing to walk and cycle."

In Northern Ireland only Kilmoyle Primary School in Ballymoney, Hexlett Primary School in Derry and Templepatrick Primary School in Antrim have had specific legislation to enforce temporary 20mph speed limits.

The Department of Infrastructure said implementation can only take place with the support of the PSNI, the successful completion of the necessary legislation to allow enforcement and the availability of resources including finance to allow delivery.

There are three schools in Newry, Armagh and Craigavon where the legislative process for part-time 20mph speed limits has begun. These schools are located next to 60mph roads.

Construction is already underway on the signage for the temporary 20mph speed limits outside St Peter’s Primary School in Collegeland Co. Armagh. Its principal Jim McAlinden says the school has campaigned for the measures for over four years.

He said: “It really is a situation where parents and community groups raised awareness and lobbied to have the speed limit changed. We are a rural school with a 60mph stretch of road right outside our gates. Understandably parents were concerned about the risk to their children particularly at the start and end of the day.

“Thankfully we’re now in a situation where we’re awaiting legislation to enforce the new limit that has been granted but work has already got underway in installing the signs. This means there will be flashing signs indicating that it is a temporary 20mph speed limit during school hours and school term time.”

Lorraine Quinn has two children who attend the school and has had personal experience of how dangerous a 60mph road can be beside a school.

She said: “We had an incident with one of our children outside the school where had he stepped out another foot it could have been fatal. On that particular day our eldest, for a split second, made the wrong choice and got into the car on the road side. As St Peter’s is situated on a blind summit a bus that was travelling at the legal speed of 60mph missed him by inches. It was horrendous.”

The new speed limit arrangements are expected to be functioning outside St Peter’s in time for the new school year in September.

However just 30 miles away, Killean Primary School near Jonesborough is also situated on a 60mph road, but there are no plans at present to introduce temporary speed limits at the site.

The school’s principal Louise Campbell said: “We are situated in beautiful area in rural south Armagh, as such there are quite narrow roads. If you can imagine cars and heavy goods vehicles driving down the road at 40, 50 and even 60mph.

“It’s extremely dangerous especially because we have to cross the road to get to our playing fields. It would make everybody more comfortable if we had the 20mph speed limit. We realise this costs money but you have to put it in terms of the potential injury or loss of life to children and investment in that area is worth any amount of money.”

A study was carried out by the Department for Regional Development in June 2014 to examine the most effective traffic calming measures for outside schools across Northern Ireland. It found that there were a number of engineering measures which can be introduced to create safer roads around schools such as coloured markings, central reserves and lay-bys.

However the study concluded that the most effective system was the introduction of enforceable part-time 20 mph speed limits.

Sandra Leo is from the Risk Awareness and Danger Avoidance Responsibility Centre (RADAR). She believes that vehicle speeds remain too high outside schools in Northern Ireland.

RADAR has a state of the art educational facility in Belfast's harbour estate that includes a life-size model village. Its aim is to teach children and young people about road and transport safety as well as criminal justice.

Ms Leo believes more schools in Northern Ireland should have part-time 20mph speed limits.

She said: "When you consider that we have more than a thousand schools across Northern Ireland and only a small number currently have those protections it is surprising.

“Especially when you consider that many of our schools are beside main roads, with some at 60mph. We know the outcome can be much different depending on the speed of a car when a collision occurs.

"A child hit by a car at more than 40mph are significantly more at risk than those who are hit at 30 or under. It further amplifies the risk and potentially doesn’t need to, so I think it’s something that should be looked at.”

A spokesperson for sustainable transport chairty Sustrans said: "Detail Data has produced a really useful map showing collisions around schools and we are very supportive of 20mph but not just at school gates. We want safer journeys to schools for all children and therefore want a default 20mph in residential areas.

"Government also needs to look at safer infrastructure to encourage more active travel i.e. children to walk and cycle to school. What we have at the moment is a vicious circle of parents afraid to let their children get to school on their own steam and as a result massive congestion around the school gates.

"We deliver the Active School Travel programme on behalf of the Dept for Infrastructure and Public Health Agency which reaches 200 schools. We have just been funded to continue delivering this programme for 5 more years and hope to expand its remit."
