Formula correctness

 * Regarding the formulas in "Examples", I wrote since I doubted the correctness of the formula. If there is a brick wall it corresponds to immediate deceleration, no zero deceleration. This is my theory. So $$ \frac{1}{a_l}$$ should not be $$ \frac{1}{0}$$, but instead $$ \frac{1}\infty$$, that is $${0}$$. Any comment? --BIL (talk) 13:14, 21 September 2009 (UTC)


 * You're absolutely right. The correct "number" is infinity, not zero. But how do you put that into the MathML? Maury Markowitz (talk) 01:08, 22 September 2009 (UTC)


 * Like I just did it. For information about the math languagae, see TeX, and read the external references, like the first one . It is not MathML, that is something different. --BIL (talk) 08:46, 22 September 2009 (UTC)

For RPT: You used:
 * $$T_{tot} = \frac{3}{8} + 0.01 + \frac{1.1 \times 8}{2} \left(\frac{1}{2.5} - \frac{1}{1} \right)$$
 * $$n_{pas} = {3}\times \frac{3600}{0.2}$$
 * $$T_{tot}$$ = 3 seconds ; $$n_{pas}$$ = 54,000 passengers per hour

However: It can notbe lower then $$T_{tot} = \frac{3}{8} + 0.01 = 0.385s $$
 * which occure when the cars are pretty close

Then the capasity becomes 28000 passengers per hour

Blacklisted Links Found on the Main Page
Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessarily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true. Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

Below is a list of links that were found on the main page:

 * Triggered by  on the local blacklist

✅ This issue has been resolved, and I have therefore removed the tag, if not already done. No further action is necessary.— cyberbot II NotifyOnline 20:58, 9 April 2014 (UTC)
