In route planner, compute driven distance and ferry distance

[mraross]

There are a couple of ways to support this:

Add drivenDistance and ferryDistance to route results in addition to route distance (which is sum of both driven and ferry distances). OnRoute counts inland ferry travel as driven distance so maybe we need inlandFerryDistance and coastalFerryDistance instead of just ferryDistance?

This enhancement is related to determining a person's daily commute to work. The driven distance between their home and the work site will grant them some benefits. The intent is to reimburse an employee for travelled distance and when the vehicle is sitting on the ferry, it is not using fuel or incurring wear and tear. This information needs to be known for planning and budgeting purposes prior to hiring.

Driven distance is also useful in logistics planning to compute fuel consumption and wear and tear.

This enhancement was requested by MoTi but, clearly, it will benefit Ministry of Finance and all financial admin areas across government. It will also benefit logistics planners such as Wildfire and BC Mail Plus.
