Rethinking Malahat Solutions

How much could bus improvements and TDM
incentives reduce crashes? Shifts from
automobile to transit tend to provide
proportionately larger crash reductions, so each
1% vehicle travel reduction reduces crashes
more than 1% (Litman 2019; Small 2018;
Stimpson, et al. 2014). Two factors contribute to
this effect. First, higher risk drivers are
particularly likely to shift mode. For example; a
senior who finds high-speed highway driving
difficult, a lower-income motorist with an old
unreliable car, and a celebrant returning from
drinking, is particularly likely to shift from
driving to public transit. Second, since about
70% of casualty crashes involve multiple
vehicles, vehicle travel reductions reduce risks
to both the motorists who drive less and to
other road users. According to one study, a 10%
reduction in vehicle mileage reduces total
crashes by 14% or more (Edlin and Karaca-
Mandic 2006).
This suggests that, if public transit reduces Malahat traffic by 20%, crashes on the entire corridor
should decline by more than 20%. This provides much larger total crash reductions than safety
strategies that only apply on the Malahat (Figure 9). For example, point-to-point speed cameras
might reduce Malahat crashes 10-20% (assuming speed-related crashes decline by half, which
represent 25-30% of all casualty crashes). Similarly, grade-separation might reduce Malahat
Highway crashes by 30-50%, but by inducing additional vehicle traffic is likely to increase
downstream crash risk, including risks to pedestrians and bicyclists.
What about rail transit? Rail is considered more comfortable and prestigious than bus travel, so
some people argue it would attract more passengers, but bus transit has other advantages:
• Proposed bus service is far more frequent than rail, providing 43 daily departures in each
direction, compared with one to two daily train departures proposed in the South Island
Transportation Strategy, and two to four daily departures proposed by the Island Corridor
Foundation (ICF 2022).
• Buses would be faster than rail for most trips. Buses can operate at 80-100 kilometers per
hour (kph) on the Malahat, and bus lanes allow buses to avoid congestion between Victoria
and the West Shore. Trains would operate at 38-55 kph between Victoria and Shawnigan
Lake, and 50-90 kph from Shawnigan Lake to Courtenay (WSP 2020, p. 49).
• Buses can serve more destinations and routes, for example, providing direct service from
downtown Victoria, UVic and Langford to Shawnigan Lake, Duncan and Nanaimo. A train
would stop at four stations north of the Malahat, and five south, and terminate in Vic-West,
requiring passengers to transfer to buses to most destinations (MoTH 2020c, pp. 23, 28).
• Bus fares are much cheaper than rail. Interregional bus fares would be no more than $5
between Victoria and Nanaimo, compared with $20-30 one-way fares proposed for rail.
