MISC | Data and Information on Circle/Ring Lines within Metro Systems

Hi I am a college student doing some research on metro and subway networks. Within my work I will discuss the connectivity benefits that come with circular lines or ring lines (some examples of such a line include the U3 line within the Hamburg U-Bahn or the Koltsevaya Line in Moscow). However, I am having a hard time finding any research papers or data that discuss circular/ring lines. With that being said, can anyone recommend some information. I appreciate the help!

Good suggestion, Falubaz. Micro puts in a lot of work to his site and I think he does an excellent job.

I have actually come across this site. It was a great starting point and it allowed me to see several examples of the phenomenon. However, I'm trying to find some data or research that has examined the effects such lines have on a network. For example, have circle lines proven to be successful in the long run. All in all, I appreciate the assistance. Thanks!

You can compare the ridership on the circle lines, then count the interchanges and how much more transfers they offer to the riders or how much time one can safe when avoiding the city center transfers. I think you wont find all data you are looking for. More like you'll find pieces of needed infos and have to put them together and make some conclusions.

Arguably, the worlds busiest railway line is a circular line - take a look at the Yamanote line in Tokyo.

Also, take a look at the impact of the new Beijing circular lines - both 2 and 10.

An indirect proof of their success is that a lot of new circle lines are still being planned and built. The transport operators wouldn't do that if they wouldn't expect the circle lines to be successful. And they probably wouldn't expect that if older circle lines in other cities hadn't proven to be successful.

Of course, one circle line makes usually much more transfers than a single regular line. It creates shortcuts and removes bottlenecks in the metro system.
