busesonly

Busesonly is a term used in urban transportation planning to describe infrastructure and policies that prioritize bus travel by designating road space or operating rules that favor buses over general traffic. It commonly refers to dedicated bus lanes, busways, and measures such as traffic-signal priority that streamline bus movement. In practice, "busesonly" may denote permanent or time‑restricted lanes that only buses (and sometimes authorized vehicles such as emergency vehicles) can use during certain hours.

Design and operation: Dedicated lanes are marked with signage and pavement markings, sometimes with physical separators. Access is restricted through signage, and enforcement may be carried out by cameras or patrols. Some systems allow bicycles or motorcycles in certain bus lanes, depending on local policy. Busways are fully separated rights-of-way that operate independent of general traffic and often link to bus rapid transit networks. Queue jumps and priority at intersections can further improve performance.

Impact and considerations: Benefits include faster, more reliable service, increased rider satisfaction, and higher bus mode share. Challenges include installation cost, right-of-way competition, potential spillover congestion for adjacent lanes, and the need for clear enforcement to maintain reliability. Equity concerns may arise if bus-priority measures divert space from other essential services or pedestrians. Successful implementation typically requires complementary land-use planning, fare integration, and transit-signal priority that is well-coordinated with traffic engineers.

In practice, many cities implement busesonly as part of broader bus rapid transit programs or general bus lanes.
