My daily commute to work is approximately 12.5 miles each direction. As I attempt to make this trip as quickly as possible (at least going to work) in order to arrive on time, I have become something of a student of the art of traffic, and I would like to share some of my findings. Please note that a few of the conditions of my trip are a bit unique and need to be taken into consideration: particularly, of the 12.5 miles, approximately 8 miles of this trip is straight on one road with two lanes going in each direction. There are 27 traffic lights to be contended with in this distance. The road is not particularly congested, but there are a good number of daily commuters with whom I share the road. Here are my insights for you to make the trip as quickly (and, potentially, as safely) as possible for you as well as your fellow commuters:
1.) Take as many reasonable measures as possible in order to ensure that you make it through the green light.
When you get stuck at a light, you not only lose the time that you must sit, but you also potentially lose time due to the inefficient driving techniques of the people that you are effectively letting get in front of you. If time is important, go through the intersection on the yellow light to make sure that you get in front of the slow pokes. It should go without saying, of course, that if you must take some chances when going though on a yellow light (such as accelerating or going through close to the red light), be very alert--particularly for drivers facing you attempting to make a left turn and for police officers.
2.) Remain in the right lane as much as possible--unless most of the left-hand turns on your route offer turn lanes.
Many people advocate always staying in the right lane since getting stuck behind a car making a left turn destroys efficiency, but I argue that when approaching intersections with a left turn lane, make sure to stay in the left lane since this will often be faster. Most people take their right turns too slowly and will force you to brake (and possibly miss the light--see #1). If there is no turn lane, you will have to use your judgement regarding the odds of the cars ahead of you making a left turn. (If you drive the same route every day at the same time, you may be able to learn where other drivers are going as well--at least on your little stretch of road.) Generally speaking, it is usually faster to be in the right lane in such a case. Note that the people who take these left turns have probably not planned their route effectively, and they are doing both themselves and you a disservice. Learn from the company that runs the tightest ship in the shipping business, UPS: "In fact, the parcel carrier has technology in its systems that help map this out routes that minimize the number of left turns the driver has to make."
3.) Focus on driving--and nothing else, especially talking on a cell phone.
A recent study concludes that drivers talking on their cell phones are adding to the time of your daily commute--up to 5%-10%. Plus, they are less safe drivers and are as dangerous as drivers who may be legally drunk.
Keep these tips in mind to arrive at your destination quickly and safely.
