Traffic volume & mix

Traffic volume

Heavy vehicles (%)

EV share of light vehicles (%)

Default EV share is 2.5 % of the light fleet. Typical current range is 1–5 % on most corridors, up to 10 % or more in some urban pockets.

Length interpretation

Why this matters

If you choose Path length, time difference compares travelling the detour section at the detour speed with the same length at the original speed. If you choose Extra distance, time difference is the time to drive only the extra kilometres at the detour speed. Selecting the appropriate interpretation is important for accurate results.
