Shared Space is a relatively new way of approaching the design of public outdoor spaces, where the strict separation of traffic flows is abandoned. Busy areas with many external visitors, such as regional shopping areas, major public transport hubs, or main traffic routes, are not suitable for Shared Space.
Every traffic planning solution, including Shared Space, involves risks. Special attention is required for vulnerable groups and quiet vehicles. Because mixing traffic flows can create a relatively chaotic traffic scene, this is especially important for people with visual and/or cognitive disabilities, children, and the elderly.
Guiding principles are as follows:
• Shared Space should only be applied in areas where the required sense of community can also be expected. Often, these will be small-scale projects where the user feels like a co-owner.
• Equality can only be achieved when speed differences within and around the Shared Space area are minimal. Shared Space should only be applied in areas with a maximum speed of 30 km/h. Through auto and bicycle traffic must be provided with an appropriate alternative.
• Shared Space is primarily a pedestrian domain. Vehicles (cars, (motor)bikes, etc.) are guests and should also feel like guests.
• The design of a Shared Space area should provide sufficient structure for vulnerable people. This includes using clear guide lines, obstacle-free routes, clear sight lines, sufficient safe crossing points, and creating clearly recognizable safe zones, known as Safe Spaces, where pedestrians encounter no other traffic.
• Before designing the traffic area, it is necessary to consult accessibility experts and conduct user research (through them). After implementation, experiences should be evaluated, and any issues should be resolved proactively.
Safe implementation of Shared Space requires a recognizable layout for all target groups, along with clear and sustained communication. If the aforementioned principles cannot be met, it is advised not to use Shared Space as a design choice.
