Faulty Stoplights

[adventure]

mga sir naisipan ko lang pong ilagay ito kasi marami akong nakikita na stoplights na sobrang tagal mag GO at sobrang bilis mag stop.Sino po ba ang dapat nag aayos ngstoplight kasi po ang pgkakaalam ko is dapat 30sec ang STOP and 30sec ang GO like the stoplight in araneta going to s.m centerpoint sobrang tagal ng go at sobrang bilis ng stop ciguro makaka 3 stop and go kami bago maka right turn para maka punta ka sa quezon ave going to sto domingo church.tapos kapag galing ka naman ng banawe going to toyota or nissan q.ave ang bilis ng stop at ang haba ng GO kaya yung mga nasa aranete naiipon yung mga kotse tapos my kasabay ka pa ng 6 wheeler na truck kaya nagkakaroon ng volume yun sana po maging ok itong thread sana mas marami pa mag post ng mga stoplight na not functioning well or the stop light that is on even if not anymore needed

traffic management is a science. computed po yan depending on the intersection kung gano katagal ang green at red. ang may standard ay yung transition from green to yellow to red.

sa ibang bansa they use heat sensors para malaman kung dapat nang i switch ang traffic light from one lane to the next. dati nag-experiment sila nyan dito pero di gumana, kase lahat ng intersection traffic. nalilito lang yung computer.

Actually, almost all traffic lights of Metro Manila ay naka START system na (don't know what that means). Basta it is also the traffic light system used in most of Australia. Meron silang kinabit na mga sensors under the road to monitor which lane have more traffic volume, yung ang i-priority. Ang problema, yung mga jeep, kahit GO na, naka STOP pa rin sila waiting for passengers. Kaya nalilito yung computer.

Also, hindi naman standard yung 30sec na GO, then 30sec na STOP. It depends sa traffic history nung intersection kung aling lanes ang mas kelangan ng longer period of green light or red light. Also, almost always, major or wider roads will tend to have a longer green light than minor roads.

ang masama kasi pag nakialam na yung mga enforcer... hindi sila coordinated... then hindi rin nila ma prioritize yung mga nasa main road...

sa tingin ko, kaya naman i automate ang traffic system natin... basta mag-isip lang na mabuti hindi banat ng banat lang... Siguro i set ng mga taga taas yung path na gustong maachieve.. then i set stage by stage, tapos coordinated lahat ng city... hirap din eh.. bawat mayor gusto sila mag papatupad ng traffic sa city nila.
kelan kaya magkakaisa ang mga Pilipino.?????????????
kaya naman natin....ayaw lang...

sa tingin ko most, if not all, stop lights in metro manila already have sensors. There was this one time in araneta na hindi tama yung pagpwesto ko sa mga guhit, halos nasa intersection na ako nun, atleast 5 mins na ako nakastandby hindi talaga nag gregreen yung ilaw. Ako lang nakapila non. Tapos naisip ko na baka may sensor na nga yung ilaw, inatras ko yung kotse ko at pinuwesto ng maayos, ayun biglang nag green

Hindi po ako makapaniwala na may sensors na ang stop lights ng metro manila iyong bang ala DMV ng US? Kasi ako ang lagi kong biyahe ay Pque at Makati CBD lang.. Sa Makati kasi may segundo iyong traffic lights at laging ganun ang behavior nya.

It's not always sensors. Some stoplights are actually on a "schedule". The one at Festival Mall does standard time in the morning, then, in the evening (at about 9pm), it's switched to "night mode".

Meaning, if you're exiting the mall, you have exactly five seconds to respond to the stoplight after it turns green. When you've got a dozen cars piled behind one guy who doesn't know this (and who gets stuck as the light before the poor idiot can put the car in gear....), you have a lot of horn-blowing and cursing happening. :lol:

I've seen other lights that enter "night mode", too, making the window for the crossing road shorter, automatically, regardless of volume.

Kinakalikot din naman kasi ng mga traffic enforcers yung mga stoplights.

I've seen enforcers fiddle with the timing of the lights, disable them, make them faster and turn them off. At major "kotong" points, this becomes a good modus operandi. A few years ago, they'd programmed the Ortigas-C5 stoplight to flash yellow very briefly (about three to five seconds) before going red. Now this is an intersection crossing six to eight lanes of road... with five enforcers waiting at the other side.

No siree... not suspicious at all. :hysterical:
