Mischverkehr

Mischverkehr, literally “mixed traffic,” is a concept in road traffic planning used to describe situations where different road users share the same roadway without dedicated lanes for each mode. In this context the main participants are motorized vehicles, bicycles, pedestrians and, in some settings, public transport such as trams or buses. The term emphasizes the coexistence of varied speeds, masses and maneuverability.

Mixed traffic is common in urban centers with narrow streets, town centers, and residential areas where space is limited. It contrasts with segregated or separated traffic, where bicycle lanes or pedestrian zones are physically distinct from motor vehicle lanes. Safety depends on mutual awareness, appropriate speed levels, clear visibility, and well-designed intersections.

Design approaches aim to manage conflicts rather than eliminate them. Measures include traffic calming to reduce speeds, decreased lane widths, shared lanes marked with road symbols, raised crosswalks, and improved signage. Some jurisdictions implement 30 km/h or 20 mph zones to enhance safety for vulnerable users in mixed traffic environments.

Policy implications include adopting “complete streets” principles that prioritize safety and accessibility for all users, rather than maximizing vehicle throughput. In practice, planners combine regulatory rules with street design to balance efficiency, mobility and safety. Where feasible, emerging concepts of shared space seek to reduce barriers between user groups, while maintaining order at conflict points.
