Variable message signs for cyclists in Copenhagen

The City of Copenhagen is constantly developing its cycling infrastructure. Having already an extensive network of cycle lanes- separated from motorized traffic, the time is right to test and implement a layer of digital technologies on top of the physical infrastructure. This digital layer includes technologies for bicycle traffic information services such as variable message signs.2017年春季，为骑自行车者专门安装了五个可变消息标志。标志可以显示有关前方自行车道路上拥塞的信息，以及旅行时间，活动，道路工作等等。大部分的这些信息is gathered through sensor equipment and other connected data sources. The signs are to be evaluated based on their capacity to induce behavioural change – like alternative route choice by cyclists – based on the information shown.

History and purpose

Copenhagen’s extensive network of dedicated bike lanes and complementary infrastructure (separate signal heads at intersections, destination and distance signposts, etc.), is the result of 30 years of prioritizing cycling as the transportation mode of the future.

The city of Copenhagen has been successful in achieving a modal shift away from motorized transport towards cycling. The number of trips by bicycle in the inner city exceed those by car, while 63% of the population in Copenhagen prefers the bicycle for commuting to work and education. Furthermore, 30% of all trips with start and/or stop in Copenhagen are made by bicycle. Occasionally, this results in congestion on the bike lanes, while road works or events on central bike corridors can become a nuisance for tens of thousands of people per day.

For this reason,2014年，通过公私创新合作，哥本哈根市与一群企业家和公司一起构思了开发骑自行车者的可变信息标志的想法。交通信息目的的可变消息标志通常用于几十年来高速公路上的机动流量。现在是时候看看这些标志对电动车辆的行为改变效应是时候了，可以转移到骑自行车的人的交通。

The primary issue to be solved is congestion. Even though segregated bike tracks are already 3 meters wide some places, with 50 or more cyclists per minute, we still see congestion on the bike tracks. Furthermore, by offering relevant and real time traffic information and route suggestions specifically to cyclists,the idea is to inspire cyclists to use less used tracks whereby the overall cycling capacity of the city infrastructure could be more effectively used.

In an infrastructural and behavioural perspective there is potentially a lot to gain from the signs. The bicycle is a very flexible mode of transportation and usually in Copenhagen one has more route choices on the bike than in motorized vehicles. On the other hand people usually exhibit fixed, routine based behaviour. Sometimes, the cyclists use routes that are less efficient because of habit and lack of knowledge of alternative routes.基础设施改变，交通信号协调，创造“绿色波浪”，建造了新的自行车道，现有的自行车道被加宽，制作其他路线，这是常用的，对骑自行车的人更有效。随着行为心理学家展示，由于习惯，这些变化并不常见，大多数骑自行车者始终继续相同的路线。

The variable message signs also have the purpose of supporting Copenhagen’s growing cyclists’ community awareness of the impact of biking on the city infrastructure and environment.Besides the practical information regarding congestion, road works and events, this is achieved by showing information on air quality and comparative travel times between cars and bikes, showing that the bicycle is the fastest mode of transportation in peak hours in Copenhagen. In this way, cycling is a more attractive mode of transportation in the City of Copenhagen – not just individually - but also showing how cycling is part of the solution to the challenges of the city as a whole, with regards to for instance traffic safety, lowering pollution and fighting climate change. The variable message signs contribute to cyclists becoming aware of and spreading consciousness of the benefits of cycling in the city.

最后但并非最不重要的是，骑自行车者的可变消息符号充当城市交通管理人员在实现城市为流量设置的服务目标方面的工具。哥本哈根市为所有运输方式设定了某些特定的服务目标，但特别是骑自行车。到2018年，哥本哈根市将减少特定走廊上骑车人的​​旅行时间10％，并减少停止量，尤其是骑自行车者的滋扰，达到10％。这将使骑自行车更具吸引力，并将邀请大部分人口使用自行车而不是汽车。

The experience When cycling in Copenhagen as part of your daily commute, you usually know where you are going and how long it takes to get there. For this reason regular commuters seldom use mobile apps or other route planning information services for their daily trips. While cycling along a corridor – the same corridor that you always take to or from work – you see a congestion warning on the newly installed variable message sign as well as an alternative route suggestion. The route is vaguely familiar to you, but not one you would take on your daily commute. You choose the alternative route and you find out that certain changes in the infrastructure – maybe the bike track has been widened, maybe there is a new synchronization of the traffic signals creating a green wave – which were not there when you originally chose your route to work months or even years ago. These changes might make this route more attractive for everyday use or only when there is congestion on your preferred route. In any case you are aware of more choices now and your everyday habits and behaviour is influenced by the variable message sign. On the way home from work, you pass another signs informing you of a large event the next day – a marathon in the inner city maybe – cutting off access to the quickest routes to or from work which means that you have to take a detour which will make your trip 15 minutes longer. Knowing this you plan ahead, leave earlier from home the next day and get to work on time anyway.

数据和骑自行车者交通管理

The variable message signs are the first truly variable signs for cyclists in the world. They are not built to solely serve one purpose and can therefore display any relevant information as long as the data is present. For this purpose, as well as for cyclist traffic management,the City of Copenhagen is installing an extensive sensor network for cyclists。

传感器网络此时确实计数骑自行车者并在交叉点处测量队列长度，然后，此数据驱动屏幕上显示的拥塞指示。流量数据被送入City流量管理平台Mobimaestro，根据哥本哈根市设定的场景自动运行变量消息标志。在不远的将来有可能向骑自行车的人通知某些路线的空气污染，并提出空气污染较少的替代路线。

结论

The amounts of cyclists and the political will to advance cycling even further still drives innovation in Copenhagen towards an improved cycling infrastructure. To accommodate the large amount of cyclists in the existing infrastructure Copenhagen has installed variable message signs exclusively for the use in cyclists’ traffic. These signs will be piloted in 2017 and it will be investigated whether the behavioural effects of variable message signs on motorists can be observed in cyclist traffic. If effective, the variable message signs will throughinformation about congestion and other incidents disperse cyclist traffic, thereby using the city’s cyclist infrastructure more efficiently。
