Actually, inadequate lanes do contribute to congestion. The traffic will always be pretty much standard… the time of transit however is slowed so it may seem like there are less cars… but no, it is less road. Also, the curvature of the roads – especially on on ramps can affect visibility of oncoming traffic and not providing for a properly lengthed merge lane is also a big problem. Some things that can help slow down (prevent speeding at merging areas/onramps) so it is easier to merge is having islands between the right and left lanes with greenery, more lights/slowdowns and providing a fast lane for carshares and buses. Building in service roads and bypasses also decreases the congestion.
