The traffic system of Germany’s capital with around 3,5 million inhabitants in the metropolitan region is very complex. The core system consist of a 5.360 km street network, 1.030 km of bike lanes, 15 rapid transit lines, 10 subway lines, 24 tram lines and 149 bus lines. Recently 2 bike sharing and 8 car sharing schemes were added to the system.

Compared to other European capitals the share of non-motorized transportation is already on a quite high level. Only 31% of all trips in Berlin are made by car (London 37%, Rome 68%, Barcelona 26%). With 324 cars per 1.000 inhabitants Berlin has a remarkably low rate of motorization compared to other large cities. More journeys are made in the city centre with public transport, on foot or by bicycle than by car and the city aims to reduce the CO2 emissions of motorized traffic by 10% until 2020.


The main focus for the Berlin pilot is on the reduction of CO2 emissions by changing the modal split towards "greener" modes, i.e. by increasing the share of cyclists and public transport users, ideally also by turning car drivers into users of bikes. Special attention will be paid to the increase of safety for cyclists. With the large scale field trial, this all is integrated in the Berlin STREETLIFE game "BikeRider".

Current Experiment

Multimodal trip information using real-time information from different sources is the basis for the activities of the large scale field trial. This field trial was performed from March to May 2016. Information is made available to the people via the Berlin STREETLIFE mobile App. It integrates inter-modal routing for public transport, walk, bike, and bike sharing. As a unique selling point of the Berlin STREETLIFE App, cycle routes try to avoid known accident hotspots and dangerous segments of the Berlin street network. In the game “Bike Rider” users are able to collect "CO2-reduction points" which encourage them to choose green transport modes. 

As a main research question of the Berlin pilot the impact of gamification and of an integrated “safe” routing for cyclists on users’ mode choices for daily mobility routines is to be investigated. Data collected with the large scale field trial will be further analysed in order to quantify carbon emission savings and improvements of the overall transport system performance. Therefore, advanced impact simulations will be applied.

First data analyses show that there is a positive impact of informing transport users about options and alternatives – and about the impacts personal decision may have on the environment. Also the integration of trip planning into a competitive game already revealed promising results and findings.   

Actual information about the field trial, technical descriptions, scores and the App download link are given on the Berlin Pilot News page.
