The idea of car share lanes baffles me. Unless this new lane has been added, it is just reducing road capacity. She points out it'll save time for commuters... but also says a large number of cars have one occupant. Perhaps this is because they are a majority commuters - who don't take friends to work with them
This lane is actually a new piece of road, not a reallocation of existing road space.
However, given that the general trend is for the average number of employees at a workplace to reduce, and the average commuting distance to increase, the odds against having a colleague with whom you can share a car are increasing all the time. Add to this the increase in flexible working and unpredictable hours – how many workers nowadays really do work fixed, predictable hours?
Take a four-lane road where one lane is converted to HOV. If the proportion of multi-occupant vehicles is under 25%, then the HOV lane will be under-utilised and the overall efficiency of the road will be reduced. If it is over 25%, then they will derive no benefit from it.
The scheme is only really going to be effective if it actually leads to a large increase in car sharing, which given the points raised above is unlikely. Otherwise it is simply an exercise in politically correct gesture politics that leads to a less efficient utilisation of roadspace.
In the US, finding that many HOV lanes were under-utilised, they have converted a lot to HOT (high occupany/toll) lanes which can be used by single-occupant vehicles on payment of a toll.
