if la lacks freeway 'capacity', that what about san francisco?

what a city lacks in the freeway dept, it can make up with public transportation, at least to a degree. la would have a hard time tearing down homes and businesses to build more freeways, but it could certainly improve its rail transit system.

You are crazy, Miami has a terrible freeway system, along with just about every Florida city.

According to Wiki, the Miami metro(or South Florida as people call it) has only 16 freeways within the area of 15,896 km and 5 million+ people.

Miami's problem is that's it's very long north south. On I-95, you'll hit suburbs for over 90 miles in a row.

Around here in southwest Virginia, many of the roads aren't quite in that bad shape but they aren't as good as they used to be - and not nearly as bad as they are in SoCal. Interstate 81 in western Virginia is dangerously overcrowded, with 6+ lane traffic on a 4-lane road (5 lanes where there's an extra lane for slower trucks to go up a mountain). Inerstate 581 happens to have a series of cloverleafs along its length, which are notorious for major weaving problems - they really need to be rebuilt...

The U.S. also has some unnecessary standards as well. Interstates are supposed to have a 20 ft median, which is unreasonable. It's technically for drainage and safety, but there are more efficient ways to do that as well.

Agreed imagine how much land is being used inefficiently. Terrible for the environment, as extra concrete destroys a lot of land and does relatively nothing.

I-81 is an alternate route to the heavily traveled I-95 for truckers and is growing in popularity. Of course, the state doesn't have the money to upgrade the road but it shouldn't anyways. Virginia has and should continue to support moving that trucking freight to railroads (there are a couple that parallel I-81).

The problem is that it lacks capacity (The LA metro freeway system is very minimal when compared to population), and the pavement quality is low, or even unacceptable to European standards.
LA has plenty of freeways. It needs expanded commuter rail (no more sharing of track by passenger and freight trains, which means laying more track) and more mass transit- which it is building.

Put HSR in the medians of freeways.

Actually, it has one of the least developed ones in the U.S. for the size of it's population.

And who's gonna buy all those right-of-ways for commuter rail? Every square buildable inch in LA is build.

Freeway lane-miles per capita (US urbanised areas) 1999:
http://www.publicpurpose.com/hwy-tti99ratio.htm

Does anyone know of a more recent listing of freeway lane-miles per capita for US metro areas (MSAs, not CSAs)? That would be more meaningful imo.

yeah, we need a newer one for sure. This one's 10 years old now. Although I think we can conclude that in metropolitan areas like Los Angeles the figures are even worse because they gained a lot of people but didn't expand their freeway systems.

http://mobility.tamu.edu/ums/congestion_data/

click on a city, and you'll get a PDF file with lane miles

I can calculate a list with lane miles/capita, but that's gonna need some time.

Thanks for the link.

For instance Los Angeles:

1999: 0.419
2005: 0.468

Unclear if RIV/SB is included in the first figure though.

I think those 85 are averages. You need them per city.

I want to make a similar calculation of the Dutch metropolitan area of Randstad, problem is Randstad doesn't have a defined boundary.

I'll have a look through it and do the calculations when I get some time.
