How Los Angeles works better than you think

One of the keys to maintaining one's sanity when living in LA is to know how and when to avoid freeways.  When the 110 runs clear, it takes about 15 minutes to drive from my house to USC; when it is clogged, it can take an hour.  But that is OK, because I have a (largely) non-freeway route home that takes at most 35 minutes.

One of the reasons surface streets (outside of the West Side) in most of Los Angeles run pretty well, even at rush hour, is that 90 percent of the traffic lights in LA are synced.  By the end of the year, all lights will be synced.  As a conseqeunce, despite its traffic, in most parts of LA, one needs to wait for only one light cycle to get through an intersection.  Again, this is usually even true on downtown streets during rush hour.

The cost of syncing all the lights in Los Angeles will come to $350,000,000.  Let's do a back-of-the-envelope here.  If syncing saves the average Angelino (there are 4 million) even one minute per day, and time is worth $15 per hour, syncing basically pays for itself within a year.  That is government spending everyone should be happy supporting.

I'm someone who commutes through San Francisco on bicycle, and I can tell you that "synced" traffic lights aren't necessarily something that works well: they have to make an assumption about the average speed of traffic, and if your speed is different, you're screwed.

And similarly, if you're someone on foot, or perhaps worse, someone who lives on the route, the endless stream of high speed traffic is not exactly conducive to your quality of life.

This reminds me of what the UK did last year by looking at the economic benefits of raising the speed limit last year.

Downtown LA is a screaming example of were infrastructure investment via stimulus spending should be spent on. A 10 year treasury is below 2% and you have alot of construction workers out of the job that could fill all the pot holes and build new car pool lanes around USC and downtown LA that could help with our daily commutes in general.

It can be described more roughly by the number of rooms. A studio apartment has a single bedroom with no living room (possibly a separate kitchen istanbul real estate).
A one-bedroom apartment has a living or dining room istanbul property separate from the bedroom. Two bedroom, three bedroom, and larger units are common.
(A bedroom is defined istanbul properties as a room with a closet for clothes storage.)


The size of an apartment or house can be istanbul property described in square feet or meters. In the United States, this istanbul real estate includes the area of "living space",

effective real estate laws can be a significant istanbul properties barrier to investment in
many developing countries. In most societies, rich and poor, a significant fraction of the total wealth is in the form of istanbul property land and buildings.
