My Bike Is My Car


Car Commute Time Versus Bicycle Commute Time

For years my bicycle commute was 30 minutes door-to-door each way. By car it was also just under 30 minutes door-to-door on average. This is because where I worked the parking lot for non-VIPs like myself was a good 10 minutes by foot from my office. With the bike I could park just outside the office. Imagine that! Now that my commute is longer (45 minutes each way), I’m not so sure that the car commute time would be so close to the bike commute time. Still, for both of my work sites the parking lot is far enough to add an extra 5 minutes at least to the door-to-door time. Worth considering.

In general I find that bike commute times compare very favorably with car commute times. For a brief, 3 to 5 minute car trip to the grocery store I hardly notice any difference with bike time to the same destination. Even longer trips can end up pretty even with bike time if you take traffic congestion and parking into consideration. For instance, if I were to compare two trips from my home in Sunnyvale to, say, Crissy Field in the Marina district of San Francisco, here’s what I’d probably get. Driving + parking time: between 50 and 70 minutes. Bike + Caltrain: 85 minutes. Not bad at all.

On the Study Tour in May we had a presentation given by a cycle co-ordinator from Groningen. Among the pieces of information was a measurement of car vs. bike speed in the city.

In Groningen, the average distance covered by a car in 10 minutes is just 1.6 km. By bike the average distance is 2.4 km.

Neither are very quick, but that’s the nature of rush hours, and of bikes ridden on crowded streets by people who are not necessarily very interested in going quickly.

It is by policy that the infrastructure allows higher speed by bike than by car, and it’s a very popular policy. In Groningen 60% of all journeys are by bike. The 180000 residents of the city own 70000 cars and 300000 bikes.
