行(xing)人(ren)(ren)過街按(an)鈕的(de)(de)(de)手(shou)(shou)動控(kong)(kong)制就(jiu)是用手(shou)(shou)動的(de)(de)(de)形(xing)式來控(kong)(kong)制紅(hong)綠(lv)(lv)燈的(de)(de)(de)變(bian)化，沒(mei)人(ren)(ren)過馬(ma)(ma)路時(shi)，紅(hong)綠(lv)(lv)燈一直維持車(che)通行(xing)的(de)(de)(de)狀態，行(xing)人(ren)(ren)要(yao)過馬(ma)(ma)路時(shi)，只要(yao)按(an)下按(an)鈕，機(ji)(ji)動車(che)信(xin)號(hao)燈就(jiu)會變(bian)黃燈，提醒汽車(che)司機(ji)(ji)的(de)(de)(de)注意(yi)(yi)，黃燈經過大約6秒（具體(ti)時(shi)間根據人(ren)(ren)流(liu)情況(kuang)(kuang)調控(kong)(kong)），機(ji)(ji)動信(xin)號(hao)燈轉(zhuan)為紅(hong)燈亮，而人(ren)(ren)行(xing)紅(hong)綠(lv)(lv)燈轉(zhuan)為綠(lv)(lv)燈亮，持續大約20秒（具體(ti)時(shi)間根據人(ren)(ren)流(liu)情況(kuang)(kuang)調控(kong)(kong)），然后(hou)就(jiu)會恢復到車(che)通行(xing)的(de)(de)(de)狀態，為了(le)避免惡意(yi)(yi)操作，系統設計了(le)2次按(an)鍵的(de)(de)(de)有效時(shi)間差(cha)為大約2分鐘(zhong)（具體(ti)時(shi)間根據人(ren)(ren)流(liu)情況(kuang)(kuang)調控(kong)(kong)），也就(jiu)是說在這(zhe)段(duan)時(shi)間內(nei)如果繼續按(an)鍵系統是沒(mei)有反應(ying)的(de)(de)(de)，必須等到冷(leng)卻時(shi)間過后(hou)才會響應(ying)。
行人在不同時刻(ke)觸發過街請(qing)求按(an)鈕，切(qie)換到行人過街綠燈的(de)時間間隔從6秒(miao)到40秒(miao)不等，分(fen)下列4種情形(xing)：
情形(xing)一：當機動車(che)綠(lv)燈通(tong)行大于40秒(miao)時(shi)，行人(ren)按(an)觸摸按(an)鈕，6秒(miao)過渡(du)信號后即切(qie)換到行人(ren)綠(lv)燈。
情形(xing)二：當機動(dong)車(che)綠(lv)燈(deng)(deng)通行(xing)(xing)(xing)小于(yu)40秒(miao)(miao)時(shi)，行(xing)(xing)(xing)人按(an)觸(chu)摸按(an)鈕，行(xing)(xing)(xing)人燈(deng)(deng)不會(hui)(hui)馬上現綠(lv)燈(deng)(deng)，但機器已接收到觸(chu)發信(xin)號，等機動(dong)車(che)40秒(miao)(miao)綠(lv)燈(deng)(deng)時(shi)間通行(xing)(xing)(xing)完(wan)后(hou)(hou)就會(hui)(hui)自動(dong)切換(huan)到行(xing)(xing)(xing)人綠(lv)燈(deng)(deng)。比如(ru)，行(xing)(xing)(xing)人在機動(dong)車(che)綠(lv)燈(deng)(deng)通行(xing)(xing)(xing)了(le)20秒(miao)(miao)時(shi)按(an)了(le)觸(chu)摸按(an)鈕，信(xin)號燈(deng)(deng)會(hui)(hui)在20秒(miao)(miao)后(hou)(hou)切換(huan)到行(xing)(xing)(xing)人過(guo)街綠(lv)燈(deng)(deng)通行(xing)(xing)(xing)。
情形三(san)：行(xing)人綠燈(deng)(deng)期間，再觸(chu)發按鈕，行(xing)人綠燈(deng)(deng)時間不會延(yan)長，20秒行(xing)人綠燈(deng)(deng)結束(shu)后，信號燈(deng)(deng)將先切換回(hui)機動(dong)車(che)綠燈(deng)(deng)通(tong)行(xing)，40秒后便會再切換回(hui)行(xing)人綠燈(deng)(deng)過街。
情形四：如果(guo)沒有行人觸發按(an)鈕，機動車信號(hao)將一直綠燈，行人信號(hao)持續紅燈。
行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)控(kong)制系統的組成，一般包(bao)(bao)括：行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)信號(hao)控(kong)制機、行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)請(qing)求(qiu)按鈕、行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)信號(hao)燈(deng)(deng)(deng)(deng)、機動車信號(hao)燈(deng)(deng)(deng)(deng)、控(kong)制軟件等部(bu)分。可擴展(zhan)部(bu)分包(bao)(bao)括：語(yu)音(yin)提示(shi)音(yin)柱(zhu)、LED信息顯示(shi)屏、行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)闖紅(hong)(hong)燈(deng)(deng)(deng)(deng)紅(hong)(hong)外報警設(she)備。此種(zhong)信號(hao)燈(deng)(deng)(deng)(deng)主要安裝在行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)需(xu)(xu)求(qiu)不(bu)均(jun)衡且車流量較(jiao)大的路(lu)(lu)段或丁字(zi)路(lu)(lu)口上，根據(ju)(ju)不(bu)同路(lu)(lu)段、路(lu)(lu)口行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)實(shi)(shi)際(ji)需(xu)(xu)求(qiu)等具(ju)體交(jiao)通(tong)情(qing)況，它(ta)們(men)分為全(quan)天(tian)有(you)(you)效或行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)通(tong)行(xing)(xing)(xing)(xing)(xing)(xing)高峰時段有(you)(you)效兩種(zhong)工(gong)作情(qing)況。也就是(shi)說，沒(mei)有(you)(you)行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)的時候，信號(hao)燈(deng)(deng)(deng)(deng)會(hui)自動延時讓(rang)機動車順(shun)暢(chang)通(tong)過(guo)。有(you)(you)行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)要通(tong)過(guo)路(lu)(lu)口時，按下按鈕，控(kong)制系統根據(ju)(ju)實(shi)(shi)時車流量、行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)過(guo)街(jie)(jie)需(xu)(xu)求(qiu)調整(zheng)紅(hong)(hong)綠燈(deng)(deng)(deng)(deng)配時放行(xing)(xing)(xing)(xing)(xing)(xing)行(xing)(xing)(xing)(xing)(xing)(xing)人(ren)(ren)(ren)，而與(yu)其相交(jiao)兩側的車輛則(ze)會(hui)被紅(hong)(hong)燈(deng)(deng)(deng)(deng)指示(shi)停車等待(dai)。
