本发明为了克服以上三种交通组织缺陷问题,本发明提供一种左转进口道迁移 及其两种行驶方法,解决及改善了以上三种交通组织中的其一灯控交通组织其直左 车流同时对向通行时所产生交叉冲突点及路口处待车时间成倍增加。 路口经常拥 堵，尾气排放量增多；其二无控交通组织车辆混流及交织冲突现象；其三绿波交通 组织的道路路段单向通行，路口处禁止左转带来的绕道行驶。本发明在同一种左转 专用车道设置实施两种交通行驶方法，各路口处实施二相位控制路口处车流分流， 在十字形路口不另设左转信号相位， 不存在直左对向同时通行时的交叉冲突点,尾 气排量减少；其二不实施无控交通组织，或是尽量少实施无控交通组织；其三直左 右三向车流按原设定的车速驶至路口可以不停车驶过路口，其左转车流可在左转待 越道的越道口停车待绿放或直接不停车经越道口斜越道区 ,并驶进左转进口道进路 口， 各路段不实施单向通行， 在路口处不禁止左转。 除非道路双向车道各为一条。
本发明为了解决以上技术问题所采用的技术方案是:包括两条双向车道平交道 路及丁字形路口的横向及垂直道路，在两条双向车道平交道路及一条横向和垂直道 路远离路口进口驶向车行道最左侧车道设置左转待越道，在该道往路口段道路中央 分隔处设置越道口，该越道口面向出口道,在越道口右侧灯柱上空设置道口信号灯， 在出口道车行道横断面设置道区，道区面向出口道右侧，在道区左侧灯柱上空设置 道区信号灯， 在越道口斜对面设置斜置信号灯， 在出口道最右侧设置左转进口道， 在左转进口道及出口道分隔处设置护栏或施划黄色标线将其隔开。
在以上两条双向车道平交道路中不同的路段可设置一种一控交通组织道路即 单一灯控交通道路， 还可以设置是另一种三控交通组织道路， 即灯控、速控、程控 的三控交通道路，也可以在同一路段分时段设置以上两种交通组织道路。在一控 通组织道路中进口道路口处设置施划实线止车线,在三控交通组织道路直行进口道 路口处设置施划虚线止车线。 三控交通组织道路路段设置有快速车道， 慢速车道， 及非机动车道或公非混流车道。在快速车道路面施划时速标码，在以上慢速车道与 非机动车道分隔处加 ¾半封闭护栏， 在该护栏中设有进出口。
本发明有益效果是：红绿灯周期时间短，车辆等待绿放时间短，直左车流可同 在同一信号相位时间内对向通行，消灭了路口处的交叉冲突点，各路段不实施单向 通行， 在路口不禁止左转。路口处不容易出现拥堵及混乱现象， 具有省时，直达安 全， 节能减排的优点。

具体实施方式
图一例所示是本发明左转进口道迁移第一具体实施例方式,包括两条双向车道 平交道路及一条横向道路和一条垂直道路，在两条平交道路十字形路口道路及丁字 形路口垂直道路远离路口以一控交通组织道路通行时一百米至三百米之内，在路口 处左转车流量不大时可设在一百米之内，以三控交通组织道路通行时应在一行程的 各一半行程段中间进口驶向车行道最左侧车道设置左转待越道（1)，在该左转待越 道（1)往路口段道路中央分隔线处， 设置越道口 （2)，越道口 （2)面向出口道， 在道路中央分隔线处设置护栏或隔离带（15)该护栏或隔离带（15)设置距离是两 路口全间距段， 可在越道口 （2)处保留三十至八十米不等间隔距离不用以上护栏 或隔离带分隔,在以上护栏或隔离带（15)还要开一车辆掉头缺口。 在越道口 （2) 右侧灯柱上空设置道口信号灯（3)，在出口道横断面设置道区（4)，在新建或新改 建的各道区（4)区域内暂时要配置警力指挥经过道区（4)的直左车辆行驶。在道 区驶向的左侧灯柱上空设置道区信号灯（5)，在越道口 （2)斜对面出口道右侧设 置斜置信号灯（6)，在出口道最右侧设置左转进口道（7)，在该左转进口道（7)及 出口道分隔处设置护栏或施划黄色标线（8)，在左转进口道（7)路口处设置警告 禁入标志（9)。 在左转进口道（7)其驶向左侧还可以设置公交及非机动车混流车 道（16)。在各十字形路口处进口道灯柱上空设置左转信号灯（14)。在各路口设置 施划左转导向线（10)。 还可以当丁字形路口及路段设置成以三控交通组织道路行驶时,在其横向道路 远离路口进口驶向车行道最左侧车道及其出口道横断面设置包括以上十字形路口 其路段双向车道中所设置的左转待越道（1)，越道口 （2)，道口信号灯（3)，道区 (4)道区信号灯（5)，斜置信号灯（6)及左转进口道（7)。 在垂直道路路段可以 不设以上被迁移之后的左转专用车道及其设施,垂直道路口左转车辆从原始左转进 口道进出口。左转进口道（7)及出口道分隔处设护栏或标线（8)将其隔开。在以 上丁字形路口中心靠近垂直道路人行横道设置施划左转及过街共用行人及非机动 车共用等候区 （21)。 在以上丁字形路口处横向道路进出口道前方不设直至垂直道 路方向人行或非机动车横道。 只在垂直道路路口处施划人行横道。
第一种行驶方法其一： 当图 1例所示的道路十字形路口及其道路路口处是以一 控交通组织通行时， 横向道路直右二向车辆驶至路口时遇红灯可停车等待绿放，其 左转车辆要在左转待越道（1)的越道口（2)多辆斜列式等待绿灯放行， 当道口信 号灯（3)及斜置信号灯（6)亮绿灯放行时， 多辆车一排斜列式等待在越道口（2) 处的左转车辆开始同时斜越道区 （4)，并驶入左转进口道（7) 时， 正遇路口处左 转信号灯（14)亮绿灯并进入路口。其同向直行信号灯正当绿灯放行， 当直行车辆 进路口之后将驶至路口通远方道区 （4)止车线（11)之前时， 将经历近半相位时 间左右， 道口信号灯（3)及斜置信号灯（6)此时绿灯变红灯禁止左转车辆斜越道 区 （4)，此时道区信号灯（5)亮绿灯放行， 让将驶至道区 （4)止车线（11) 的 直行车辆顺利通过道区（4)。在以上十字形路口的竖向平交道路的直右车流驶至路 口遇绿灯放行时， 其左转车流在左转待越道（1)及越道口（2)处早已在路口处直 行信号灯亮绿灯放行之前半相位之时就已经开始斜越道区 （4)并驶进左转进口道 (7)此时不停车正与同向中对向直行车流在同一时间进路口并行其道。 当以上左 转前头车流从斜越道区（4)并驶进左转进口道（7)路口处时， 横向平交道路原先 比其同向直行迟半相位时间进路口的左转车辆驶向出口道,现正驶至以上竖向道路 道区（4)止车线（11)使竖向道路斜越道区（4)的左转车流末端正受道口信号灯
(3)及斜置信号灯（6)绿灯变亮红灯控制禁止斜越道区（4)。此时道区信号灯（5) 亮绿灯让横向转过来将驶至道区（4)止车线的左转车流顺利通过该道区 （4)。
当图 4例所示的道路丁字形路口及其路段是以一控交通组织通行时， 横向道路 两对向的直行车流将驶至路口正遇绿灯时,两对向直行车流可在同一相位时间内可 停车等待绿放过路口通行,其右转车流绿放之后可以同以上的直行车流同时进路口 并右转要驶入公非混流车道驶离路口。当路口非机动车及行人拥挤时要等待大部分 非机动车过路口之后随之进路口右转。
一控交通组织通行道路的左转车辆每次斜越道区 （4) 时间限制在十至二十五 秒钟不等。其道区（4)距离路口越远， 斜越道区（4)的时间一般就越长。左转车 辆斜越道区（4)断流时间每次要在直行或左转车流前头车辆驶至道区（4)止车线 (11)之前 3至 5秒钟。其后正是道区信号灯（5)亮绿灯， 让将驶至道区（4)止车 线（11)的直行车流顺利过道区（4)。道区（4)止车线一般是不准停车等待绿放。 只供在路口处小数闯红灯驶至的车辆停待， 以免发生交通事故。
停车等待在左转待越道（1)越道口（2)处的车辆都可斜列式， 当绿放时可几 乎同时斜越过道区（4)。 当驶至左转进口道（7)入口处时要减速按前后顺序驶入 左转进口道（7)进路口。
第二种行驶方法其一，当图 1例所示的道路十字路口是以三控交通组织通行时， 竖向平交道路的直左右三向车流按原先设定的车速驶至其道路的越道口 （2) 同排 时，直右车流直接减速驶向路口，其左转车流前半相位时间不停车等侍绿放直接从 越道口（2)斜越道区（4), 其后一半相位时间的左转车流需停车等待下一次绿放, 其前半相位左转车流不停车斜越道区（4)是与前一相位红灯时在此等待的后半相 位的车辆一起斜越道区（4)。 以上同向直右二向车流将驶至路口处时，其左转车流 斜越道区（4)之后并驶进了左转进口道（7)路口处。所以此时直左右三向车流同 时驶至路口，横向平交道路左右转弯车流末端此时驶过路口并将驶至竖向平交道路 的道区（4)止车线（11)之前， 该道区 （4)正在斜越道区 （4) 的左转车流受此 时的道口及斜置两信号灯亮红灯禁止通行。 道区信号灯（5) 同时亮绿灯让将驶至 道区 （4) 的横向平交道路转过来的左右转弯车流顺利驶过道区 （4)。 横向直左右 车流按原先设定的车速将驶至各越道口 （2)处同排时， 横向道路直右二向车流可 直接驶向路口，以上横竖向道路之分是按图例序号在图下面时所视的横竖，但其左 转车流要在越道口（2)多辆斜列式等待绿放， 即等待道口信号灯（3)及斜 S信号 灯（6)跟路口处直右信号灯同时亮绿灯时方可起动一排式斜越道区 （4), 并驶进 左转进口道（7)，当左转车流驶进左转进口道（7)路口处时， 直行车流己进路口 半绿灯信号相位时间将驶至其前方的道区（4)。但各右转车流要等待直行车流过路 口半个相位时间之后方可跟对向刚驶至路口的左转车流同进路口。
以上十字形路口驶进路口的左转车流， 在两条平交道路中每次斜越道区 （4) 时间只有半相位少 3至 5秒钟。总是有一条平交道路的左转车流先在前半相位时间不 停车直接斜越道区（4), 后半相位时间停车在越道口 （2)等待下一次绿灯放行。 在后半相位时间内停车等待绿放，当绿灯放行时总是与其同向后来一相位前半相位 时间内的刚驶至越道口 （2) 的左转车流一起斜越道区（4)。 本相位前半相位时间 内先斜越道区（4)总是跟其同向车道的前一相位后半相位在等待绿放的左转车流 一起斜越道区（4), 总的来说每次左转车流以三控交通组织通行时斜越道区 （4) 只有半相位时间限制，但其所斜越道区（4)的左转车辆数是一相位的全部车流量。 当另一平交道路的左转车流在以上一相位时间过后的另一相位的前半相位,是在越 道口 （2)等待本相位后半相位时间内正在行驶中的车流一起斜越道区 （4)， 并驶 进左转进口道处（7)路口处， 跟对向等待后半相位时间的右转车辆一起进路口。 以上右转车辆在停待绿放之前本相位前半相位时间的车流还可以跟其同向直行车 流一起同时进路口驶向、公非混流车道（16)驶离路口。再由进口（17)驶入直行车 道。一行程路段距离等于一相位时间之内车流前头车辆以每小时二十五至八十公里 到达的不等路程段。 一绿灯相位时可设定从 25秒钟至 80秒钟不等。
以上道路的路口处可设置非机动车及行人过街横道,但其过街全绿灯绿放时间 只有半个相位时间,应在横道中央设置施划行人安全岛及非机动车左转等候区 (13). 在等候区（13)方格或四角处设置固定式保护措施。在等候区（13)当中地面标有 出入字样， 中央方格为行人安全岛。 其左方格为左转非机动车进口等候区（13)其 右方格为出口等候区 （13)。 在双向车道数共 4个之内还可以不设置等候区 （13)。
丁字形路口横向道路无平交道路的一侧非机动车道（12)的非机动车及行人跟 左转车流同时间从路口中心横道（22)进入出路口或路口等 ½区（21)等待。非机 动车道（14)有时也可指是公交车及非机动车混流车道（16)。 垂直道路 (20) 的 左右转弯车流禁止通行时，驶向非机动车道（12)及人行道。于此同时原先己在行 人等候区（21)等候左转或过街的非机动车及行人也同时由中心横道（22)行驶或 步行过路口。当垂直道路的左转车流红灯禁止通行时，在垂直道路两侧的非机动车 及行人往路口中心横道（22)去的， 可在此时进入行人等候区（21)等候， 当横向 道路的直行车流红灯禁止通行时， 同垂直道路 (20)及横向道路的左转车流同时起 步往横向道路经过中心横道（22)驶行过路口。
下相位同垂直道路的左转车流在同一相位时间进路口并驶进公交车专用车道 、 或另加设车道。横向道路其左转车流需停车在原始左转进口道止车线之内等待下一 次绿灯放行时与垂直道路 (17) 己驶至左转进口道（7)路口处的左转车流在同一 相位时间内进路口并各自左转。 图 2例所示是本发明左转进口道迁移图 1例所示的十字形路口一控及三控交通 组织行驶方法第一绿灯信号相位平面示意图,其直左右三向车流同时驶至路口同时 间过路口并各行其道驶离路口。其左转车流因为早己在前一相位后半俾号相位之时 道口信号灯（3)及斜置信号灯（6)亮绿灯时段就从越道口 （2)斜越过道区（4) 并驶进左转进口道（7) ,此时所以同时驶至路口。
图 3例所示是本发明左转进口道迁移图 1例十字形路口一控及三控交通行驶方 法第二绿灯信号相位平面示意图，当横向平交道路其两对向直右二向车流在路口绿 灯放行时驶进路口时， 其左转车流同时在直右绿放时， 道口信号灯（3)及斜置信 号灯（6)也同时间亮绿灯， 在越道口（2)斜列式等待过半相位时间之后， 这时开 始斜越道区（4)。以上其两对向右转车流若不驶向公非混流车道驶离路口，就要在 右转进口道等待半相位时间跟其对向的左转车流驶至路口处时一同在同一信号后 半相位时间之内进路口并转弯。
第一行驶方法其二： 图 4例所示是本发明左转进口道迁移第二具体实施例方式 丁字形路口平面示意图。当一控交通组织通行的直左右三向车流驶至丁字形路口是 路段时，横向道路的直右二向车流可在直行进口道等待绿放进路口，其右转车流还 可以因非机动车及行人拥挤时,为让路而暂停车在其右转进口道止车线内等待大部 分非机动车进路口之后，随其后再进入路口并右转。还可以驶向公交车专用车道或 经公非混流车道（16)驶离路口。再由道区（4)过后的进口 （17)驶入直行车道。 从直行车道的车辆驶向非机动车道可由出口（18)驶出。横向道路其左转车流要在 原始左转进口道等待下一次绿灯相位跟垂直道路（20) 己驶至左转进口道（7)路 口处的左转车流在同一相位时间内进路口并各行其道驶离路口。
第二种行驶方法其二： 图 4例所示的丁字形路口及其路段是以三控交通组织通 行时， 横向道路两对向的直左右三向车流按原先设定的车速驶至各自左转待越道 (1)越道口（2)同一排列时，其直右二向车流可直接往路口方向驶去。其左转车 流可直接经越道口（2)斜越道区（4)并驶进左转进口道（7)，此时以上直左右三 向车流同时在同一相位时间之内进路口并各行其道。在下一相位时间之内是垂直道 路左右转弯车流按原先设定的车速驶至路口并减速进路口各自左右转弯。
横向道路的左转车流量不大时,左转车流还可以同直右车流同时驶至原始左转 进口道止车线之内停车等待绿放。其直右车流按原先设定的车速驶至路口正遇绿灯 可不停车进路口，在下一相位时间之内横向道路左转车辆跟垂直道路的左转车流按 原先设定的车速正驶至左转进口道（7)路口处可同在一相位时间进路口并转弯。
以上行驶方法是在横向道路路段不设置左转专用车道的情况下实施的三控交 通组织通行中的左转车流与一控交通组织车辆进丁字形路口同一方法。
以上方法有利于不会因垂直道路路段不设左转专用车道。其左转车流从原始进 口道进路口使中心等待区（21)面积縮小，另外还有利于在垂直人行过横道可设置 安排全相位的间段。
从垂直道路的非机动车及行人要往横向道路非机动车道及人行道去， 或反之， 都要等待道路车辆禁止通行时， 往路口中心行人等候区（21)等候过路口或左转， 当过街绿灯放行时各行其向经过路口中心横道（22)而进出路口。
图 5例所示是本发明左转进口道迁移图 4例所示的丁字形路口一控交通组织行 驶方法第二绿灯信号相位平面示意图。两对向直行处其一向左转车辆在同一相位进 路口。
图 6例所示是本发明左转进口道迁移图 4例所示的丁字形路口一控交通组织行 驶方法第二绿灯信号相位。横向道路左转车辆在原始左转进口道与垂直道路刚驶至 左转进口道（7)路口处的左转车流及其右转车辆一同在同一信号相位时间之内进 路口各自左右转。 图 7例所示是本发明左转进口道迁移似图 4例所示丁字形路口三控交通组织行 驶方法第一绿灯信号相位平面示意图。横向道路直右二向车流按原先设定的车速驶 至路口在同一相位同时进入路口，其左转车流在上一相位后半相位时间内就已经越 道口 （2)斜越道区 （4)并驶入左转进口道（7)路口处， 所以以上直左右三向车 流因而在同一时间驶入路口。
图 8例所示是本发明左转进口道迁移似图 4例所示丁字形路口三控交通组织行 驶方法等二绿灯信号相位平面示意图。垂直道路左右转弯车流按原先设定的车速驶 至原始左转进口道路口处同时在同一相位时间同时内进路口并各自左右转弯。
以上似图 4例所示是指丁字形路口垂直道路不设置左转专用车道。 可在横向道 路双向车道设以上左转专用车道其包括： 左转待越道 (1)越道口（2)道口信号灯 (3)道区 （4)道区信号灯（5)斜置信号灯（6)及左转进口道（7)。
图 9例所示是本发明左转进口道迁移第三具体实施例方式， 图 9例所示除图 1例 所示的路口及路段所有设置以处。还可以在两条道路平交中心设置施划十字道 (19), 在十字道（19)两边缘施划由一条黄色虚线及一条白色虚线组成， 十字道（19)内 两侧白色虚线相距是 3至 4米宽不等，外两侧黄色虚线相距是 4至 6米不等宽度，外线 两侧施划黄色虚线是警告同向驾驶人不可占道行驶，内两侧白虚线警告非机动车驾 驶人不可超越。 其黄白虚线车辆可横越。 在十字道（19)平交中心方格四角设置由 水泥或钢铁构成的护栏式墩柱 (24), 该墩柱 (24)从 1米至 5. 5米不等高度， 该墩 柱直径 0. 3米至 0. 5米不等。 该立柱 3. 5米以上高度可作行入十字形或工字形天桥中 心柱 o
可以在一部分十字形路口十字道（19)白虚线及黄虚线两侧间隙之间设置每隔 相距一条车道宽度一样的固定式限速护栏墩（25), 还可以在固定式护栏墩（25) 中间设置自动调节式护栏墩（26), 虽然每条道路各车道车种有所不同， 不但可限 制直行车辆高速过路口，但还可以保护与车流同向直行的非机动车骑驶人及横道上 的行人安全，护栏墩其间距设置宽度是以需限制直行车辆的车速而定。还可以在该 直行车辆闯红灯过路口。调节初时间设在另一平交道路直行信号灯亮绿灯之后 3至 5 秒钟之内， 自动可调式护栏墩（26)由地平面下电动或地平面上自动推板开关驱动 使之慢速伸出地平面。其自动可调式护栏墩可设置不倒式或可顺车辆驶向可倒式两 种护栏墩（26)。 可顺倒是预防在启动过程时有闯红灯进路口车辆驶过。 自动调节 式护栏墩 (26)在另一道路绿灯未之后縮回地平面。
左转非机动车可以跟直行非机动车直行到另一端的等待区域等待绿放,再次直 行过街完成左转， 还可以由以上的十字道（19)经过完成左转， 其行驶方法步骤， 左转的非机动车驶进路口时遇红灯在进口道等待绿放。当直行绿 时跟直行非机动 车一同驶进路口并在道路中央等候区（13)入字方格区域内等同向直行的另一相位 绿灯亮时，沿十字道（ 19)经过十字道（ 19)平交中心四角墩柱间隙直至十字道（ 19) 另一端出字方格区域内，再次等待向右转方向绿放相位，再驶向右侧非机动车道完 成左转。
左转非机动车除两次直行完成左转以外及经过十字道（19) 以 形驶径 成 过左转，还可以 1形驶径完成左转，可以在非机动车进口道施划非机动车左转进口 小道， 其行驶方法步骤： 当同向直行亮红灯时， 另一道路直衧绿灯时，左转非机动 车可以从左转进口小道进路口处,往左侧人行横道其左侧进等候区（13),等候同向 直行绿灯时经十字道（19)进路口直至另一端等候区（13)，等候另一向直行红灯 行人过横道绿灯时，向其左侧驶离路口。左转非机动车进路口前见前左右那方向绿 灯就往那方向等候区（13)等候经十字道（19)进路口完成左转。非机动车左转流 量大的路口时， 可选择部分或全部由十字道 (19)过路口完成左转。
