Question: How should transport operators arrange locations to optimally control crowds and reduce contact between people?

Answer passage (source: UK):
page_title: Guidance Coronavirus (COVID-19): safer transport guidance for operators
section_headers: Ventilation
section_content: Organisations should consider how to increase ventilation and air flow. Where
possible, transport operators and businesses should ensure that a fresh air
supply is consistently flowing through vehicles, carriages, transport hubs and
office buildings.
To achieve this, organisations could consider:

Air conditioning. Most air conditioning systems do not need adjustment, however where systems serve multiple buildings or you are unsure, advice could be sought from HVAC engineers.
Fresh ventilation systems can operate as normal, but recirculating air systems may require adjustments to increase fresh air flow.
High-Efficiency Particulate Air (HEPA) filtration.
Opening doors and windows where possible and safe to do so.

[HVAC]: Heating, Ventilation and Air Conditioning
  [HEPA]: High-Efficiency Particulate Air

Reviewer feedback on this answer:
Although the beginning of the response briefly mentions transport operators, the answer deals with air flow, not crowd control and reducing contact between people.
Context of answer is HVAC maintenance.

section_headers: Queues and protecting passenger flows
Crowd management
section_content: 
Consider whether queues can be moved to locations with more space for safe queues. Liaise as appropriate with other bodies (such as other transport operators, landlords and local authorities) to safely manage queues and any impact on public spaces. Consider how to provide passengers and services users with information on the service.
If services, concourses or interchanges become too crowded, or queues become too long, operators should consider the full range of operational responses available, recognising the knock-on effects on other transport modes in making these decisions.
Use social media, apps and other digital methods to alert passengers before they leave home, and to help passengers stay away or disperse until there is sufficient capacity available.


Reviewer feedback on this answer:
The answer has a context of policy for operational needs not related to COVID.
This answer also provides concrete solutions, although not as many. The ideal answer would contain the text from both this answer and candidate #2, as they contain completely separate but equally useful suggestions.

Social distancing in vehicles and at service areas, stations, stops, ports and airports
section_content: 
Rearranging, limiting or removing seating to try and ensure social distancing is observed and that it can be cleaned regularly using a rota or some other tracker. This may include: 
Blocking off seats that are in close proximity to a driver or other workers and passengers.
Removing face-to-face seating.
Maximising separation for example by sitting in back left hand seat of a car.


Using floor tape, signs or paint in passenger areas to help people keep 2 metres apart, where appropriate. Using screens to create a physical barrier between people where appropriate, such as in ticket offices.
Introducing more one-way flow through areas and vehicles.
Revising maximum occupancy for lifts and ways of operating lifts.
Making arrangements for monitoring compliance to assist with further planning (for example appointment of a social distancing marshal).
Keeping in mind particular needs of workers and passengers who have protected characteristics, for example disabled people, the elderly and pregnant women.
