First off, the Carousel is officially closed...

OK, while who knows what the city council will be like in January, 2017. Let's look back in history.
Orange County in general has always cared about transportation and roads, look at the difference between Orange County and Los Angeles County in amounts spend on better freeways and roads.
Since Orange County was widening and improving the I-5 at about the same time as Disneyland being converted to a resort, the access was well designed, such as the Carpool lane exit from southbound 5 to Disneyland Drive and the flyover over Ball Road.
But almost every request that Disney has made to city, the city responds with "What about traffic and parking?", and as we can see, not just Disney, but any project in Anaheim (Such as the special Carpool lane exit for Gene Autry Way and Angel Stadium.).
As mentioned earlier, the special facility that Anaheim built to deal with "live" traffic control in the area was money well spent.
And the focus continues today. As this thread has discussed in length, the "City" wants better traffic flow, and that includes Harbor Blvd and reducing the amount of vehicles and pedestrians to other areas as best they can. Will that impact some of the guests staying current on Harbor between Manchester and Katella, yes, it will, but it is a minor issue in the eyes of the city, as they are looking at the overall situation.
And so is the county (Harbor Blvd is a main thoroughfare thought the area), OCTA, etc.
The last item at last night's council meeting was a Taxi cab issue. Amazing that the city requires a green fleet, and a certain percentage of vehicles to be ADA accessible. So it is amazing that these companies that have to follow all these regulations, verify their drivers with security checks and special licensing, and many other things that systems like Uber/Lyft are bypassing. No wonder they are cheaper, but as they say, you pay for what you get. A week doesn't go by without multiple news stories about Uber/Lyft drivers and the problems they cause.
So yes, TDA has majorly dropped the ball, and the city has forced them to make short-term fixes, but they can't make them do the long tern investments, except when projects like this one come up for city review.
Buena Park and Anaheim are looking at improving the traffic issues on Beach Boulevard currently, which is a good thing.
But you keep adding things like new areas at the Disneyland Resort, additional space for the Convention Center, now the LT Platinum project, and the possible redoing of Angel Stadium. (And one of the main goals by the Angels owner is to get more rights to develop the current parking lot, basically building parking structures and then use the remaining land to buy more shops/restaurants and housing, which of course, requires more parking overall.)
Looks like we will be playing Super Jumbo Jenga in the area for awhile.
