The New Normal
It will be a while before, if ever, that public transport returns to the pre-virus normal, even in places like Sydney which were not nearly as severely hit as China, the US, and Europe.
There are several reasons public transport demand will remain low, and these changes are perhaps permanent:
- more people work from home at least a few days a week, especially CBD office workers who would otherwise be packed both onto trains and into hot-desked offices.
- people are instructed to avoid trains and buses to ensure distancing, which people who can will voluntarily do anyway.
- unemployment rates are higher than previously.
Substitutes like walking and biking are likely to pick up some of the slack for those who work in the CBD, though more needs to be done to facilitate safe bicycling in and around Sydney (and most other English speaking cities), in particular following the lead of other global cities in instituting a much larger network of separated and protected bike lanes.
- Cui, Mengying, and Levinson, D. (2020) Internal and External Costs of Motor Vehicle Pollution. Transportation Research Record. [doi]On-road emissions, a dominant source of urban air pollution, damage human health. Emissions increase air pollution intake (and damage health) of travelers (internal costs), and of non-travelers (external costs). This research constructs a framework modeling the microscopic production of emission cost from the vehicle and link level and applies it to a metropolitan road network. It uses project-level Motor Vehicle Emission Simulator (MOVES) simulations to model link-specific on-road emissions, and then employs the RLINE dispersion model to estimate on- and off-road concentrations of pollutants from vehicles. The internal and external emission costs are measured accordingly by counting the health damage costs of travelers and gen- eral population because of exposure. The framework is applied to the Minneapolis-St. Paul (Twin Cities) Metropolitan Area as a proof-of-concept. The estimates show that highways have higher emission concentrations because of higher traffic flow, but that the internal and external emission costs per vehicle kilometer traveled are lower. The emission costs that commuters impose on others greatly exceeds that which they bear. This modeling process is replicable for planners and practitioners assessing emission costs in other regions.
