Safe Routes to School Program in Barcelona
The "Camí escolar, espai amic" (“Safe Route to School, friendly space”) program began with the aim of increasing children´s and adolescents personal autonomy, responsibility and quality of life on their way to school or while walking around the neighborhood.

The program promotes road safety education in schools through an educational program conducted within the school and the community, and changes in the environment around the school. It is led by the Municipal Institute of Education of Barcelona (IMEB) and carried out in collaboration with the Department of Safety & Mobility of Barcelona. In each education center it includes four phases: Phase 0: We start to walk, for the definition of the project; Phase I: We explore the path, to carry out the diagnosis. Phase II. We go out into the neighborhood, to create the network of friendly spaces and celebrate the work done. Phase III: We keep the path alive, to evaluate and guarantee the sustainability of the project in the school and the educational community.

In Barcelona, police data on traffic injuries is geocoded and allows time series analyses since 2002. There are around 9,000 injuries due to road traffic crashes each year, with 11,000 persons injured, around 300 severely injured, and 15-25 fatalities in the most recent years. Pedestrians represent around 13% of all casualties, with the highest incidence occurring among young and old people.

This study aimed to evaluate the effectiveness of the Safe Routes to School (SRTS) program “Camins Escolars” conducted in Barcelona from 2006 to 2016 in reducing the number of road traffic collisions and injuries in the school environment.

The study used a pre-post quasi-experimental evaluation design, with a matched comparison group, including 64 intervention schools and 63 comparison schools. Outcomes included collisions and people injured within a radius of about 200 meters around schools during school hours, using geocoded data (2002-2019) from the local police register, and contextual variables. For each outcome measure, we fitted generalized linear mixed model with Poisson distribution.

Our main product - a mobile app called OKO - makes every pedestrian light accessible to blind and low vision pedestrians. Cities all over the world struggle with making their pedestrian lights accessible by installing an audible signal. Physical audible signals have multiple challenges: they cost up to €50.000/intersection, they produce a lot of noise pollution and hence neighbours complain, they often brake, it's cumbersome to maintain them, they are not 24/7 operational due to noise pollution, etc.

OKO provides blind and low vision pedestrians with a handheld audible signal through their smartphone. OKO uses the back camera and AI to identify the pedestrian signal status. Differentiable audio, haptic and visual feedback is being used to convey that status. OKO doesn't rely on additional infrastructure to be installed and doesn't rely on a WiFi nor cellular connection. We provide blind and low vision pedestrians to safely cross the street with more ease and confidence. Our technology is game changing the market in many ways.

The IDB closes several very important gaps, left open by other road accident data which are mostly provide by police units called to the scene of an accident.

1) The IDB provides data for single party accidents, where no police might be involved. Most notably bike accidents.
2) Some accidents are not classified as traffic accidents but are closely related. These peripheral accidents are shown in the IDB. For instance, accidents in public transportation are not consider traffic accidents unless a transport vehicle is directly involved. Accidents occurring on the entrance to a subway station, or the escalator are still problematic though and can be shown with our data.
3) The IDB is set up in a way that we can look at comparatively small portions of traffic accidents in detail. This allows us to react to emerging phenomena such as E-scooter accidents.

Die Unfallstatistik der letzten Jahre zeigt, dass die Verkehrsunfälle mit E-Bikes immer häufiger werden. Das E-Bike wird immer beliebter und immer mehr Menschen sind mit einem elektrisch betriebenen Fahrrad unterwegs. Viele unterschätzen jedoch, dass es ein richtiges Handling benötigt, damit das E-Biken auch sicher ist. Die sehr wirksamen Bremsen überraschen beispielsweise neue E-Biker sehr häufig und es kommt zu Unfällen. Mit unseren E-Bike Sicherheitskursen ist es möglich, wichtige Tipps zu bekommen um sicher und unfallfrei alle Vorzüge eines E-Bikes zu genießen.

Problematic Speed for road safety.
Specifically: Excessive speed, that is to say driving at a speed higher than the maximum permitted speed as well as Inappropriate speed, which is defined as driving at excessively high speeds given the traffic situation, infrastructure, weather conditions and/or other special circumstances. Speed is one of the most important causes of road accidents: 10-15% of all road traffic collisions and 30% of fatal injury collisions are the direct result of excessive or inappropriate speed.

An increase in speed by 10 km/h leads to a risk of a fatality of 220% of the initial event, i.e. the risk has more than doubled.

The implementation of infrastructure projects and the identification and rehabilitation of dangerous points on the road network is one of the strategic axes of the RSI.

In a E-77 road axis part, in particular in an area of 4 km of the Chalkida-Psahna road, there has been a high rate of fatal road traffic collisions over the last 20 years due to problematic speed.

The aim of this project was the design of interventions related to infrastructure in order to improve road safety by enabling drivers to control their behaviour.
