Traffic Safety in 2025 – Studies in 2019:
Representativeness of road accident registers
Road safety statistics may provide a slightly different picture of the road safety situation and its changes over time depending on the statistics under review. This study describes the data col-lection and documentation process of the main road accident databases sustained by different stakeholders and compares their data content. The aim is to produce an up-to-date description on the number and type of road accidents with their severities documented in each road acci-dent database.
Safety investigation of Finnish main roads according to new legislation
The classification of Finnish main roads and their service levels was confirmed by legislation in November 2018. This study investigates the safety situation of road sections included in the highest service-level roads (levels one and two) and compares the safety of these road sec-tions with that of other class I main roads (valtatie) and class II main roads (kantatie) by focus-ing especially on accidents with fatalities and serious injuries.
Prevalence of different friction tyre types in Finland
The results of a project realised in 2018 indicated that the relative share of high-speed range friction tyres was higher than in a study conducted in 2011. However, some contradictory re-sults have also been published. The aim of this study is to estimate the extent of high-speed range friction tyre (designed for the central European market) use on passenger cars in win-tertime in Finland. The prevalence of different friction tyre types on currently used passenger cars will be estimated based on field observations.
Safety effects of the 30 km/h speed limit
Several cities (e.g. Helsinki, Espoo and Tampere) have lowered the speed limits in their resi-dential areas from 40 km/h to 30 km/h. This study aims to investigate the safety effects of the 30 km/h speed limit. It includes a literature review (experiences and study results from other countries) combined with a survey sent to city representatives (covering the extent of use of the 30 km/h speed limit and related experiences). If possible, use will also be made of the speed measurement data collected by the cities.
Accidents and dangerous situations between pedestrians and cyclists
The objective of this study is to collect information on accidents and dangerous situations be-tween pedestrians and cyclists. This will be done via an online survey directed to pedestrians and cyclists in some of the biggest cities in Finland. The survey aims to explore the experi-enced feeling of safety by pedestrians and cyclists and to collect information on accidents and dangerous situations that the respondents have experienced.
Development of modelling of level crossing accidents
Information on Finnish railway level crossings has been collected extensively in the 21st centu-ry, and the information has been somewhat updated every year. The aim of this study is to develop level crossing accident modelling by taking into account these latest updates and test-ing new variables to predict future accident numbers at level crossings.
From driver support systems toward automated driving
The prevalence of driver support systems currently on the market is known, but no information is available on their usage. This study aims to investigate the usage of these driver support systems (such as adaptive cruise control and lane-keeping assist system) via online survey directed to car drivers. Special attention will be paid to situations and environments in which the driver support systems are used, the reasons for their usage and/or non-usage, and the expected (or realised) benefits of these systems.
Collection of before-data on camera surveillance of speeding and red-light violations on the street network
Camera surveillance in urban areas has become more popular. This study collects before-data on driving speeds in urban areas, to be used in a possible future study assessing the effects of camera surveillance on driving speeds. This study could also include a collection of before-data to identify any changes in the road environment that are expected to occur following the introduction of the new road traffic law.
