Simply put, streetcars should not be mixed with other traffic on high volume arterials. Any introduction of streetcar routes need to be totally user paid and placed on the less traveled parallel streets where the surroundings can be geared more towards pedestrian activity. High volume arterials need to be primarily maintained for motorist stakeholders that currently pay the lion’s share of transportation infrastructure costs. Streetcars (and transit busses) stopping to board passengers in motor vehicle travel lanes do cause congestion.
