231203 車線の仮説と渋滞率

道路の車線がｎ倍にナると
混雑は１/ｎ×√ｎ倍にナる
と感覚的に想っていて

例えば
２車線が４車線にナると
１/２×√２倍
2.8倍空いてくる

そんなイメージです

渋滞吸収の時が一番顕著で
車線が増えた途端に
ザァッと流れ出す
あの感じです(^―^)

僕の場合はスケジュールを
切る側のケースも有るから
混雑の少ない時間帯や
渋滞の起き難い曜日などを選んで
コソコソと移動して居ます

休みの日が
皆と同じって云うのは
やはり混雑とセットに
ナりかねないですね

僕みたいな逆張りは
皆が休む日に働いて
皆が働く日に休みます

友達は当然
同志や同士とナります
若しくは職場へ
遊びに行くケースも有りますね

神奈川県の東京寄りや
千葉県の東京寄りは
車線がギュッと減って
保土ヶ谷とか大多喜まで行くと
混んでるなぁって感じがシます

もっとも
混雑の質が違うのかも
知れませんね

保土ヶ谷は車線は有るけど
台数が多い
大多喜は台数の割に
車線が少ない

あ、あくまでも
方々に出掛けていた頃
20年くらい前の情報です

そして
その情報すら
信憑性が怪しかったりシます

231203 Lane hypothesis and congestion rate

If the number of lanes on the road is n times greater than the number of lanes on the road
congestion increases by a factor of 1/n x √n
and I have a feeling that

For example
If two lanes of a road become four lanes
1/2 x √2 times
2.8 times easier to flow

That's how I imagine it.

It is most noticeable when absorbing traffic jams.
As soon as the number of lanes is increased
as soon as the number of lanes increases
It's like that.

In my case, I have to be on the cutting side of the schedule.
I choose a less crowded time or a day of the week when traffic jams are less likely to occur.
I move quietly.

Having the same day off as everyone else's is a good thing.
I have to be careful not to make the same mistake as everyone else.

If you're a contrarian like me
I work when everyone else is off.
I work on the days when everyone else works.

Friends, of course.
I work with my comrades and colleagues.
Or I go to work.
In some cases, we go out for fun.

Kanagawa Prefecture near Tokyo
Chiba Prefecture near Tokyo
Lanes are reduced to a minimum
When you go to Hodogaya or Otaki
I feel like it's crowded.

But the quality of the congestion may be different.

Hodogaya has lanes, but there are many cars
Otaki has few lanes for the number of cars

Oh, I'm just saying...
When I used to go to many places
about 20 years ago.

And
Even that information
the credibility of the information is questionable.
