two-way left-turn lanesraised mediansmedian designmedian openingsRaised medians and two-way left-turn lanes (TWLTLs) are the two most common types of median treatments on arterial streets. The Florida Department of Transportation (FDOT) has had a policy to convert TWLTLs to raised medians ...
Two-way left-turn lane (TWLTL) medians are commonly used to solve the safety and operational problems on four-lane undivided roadways caused by conflicts between through and left-turn traffic. Although the potential safety and operational effects of TWLTL medians are well recognized, there are ...
A feasible solution is to use the two-way left-turn lane (TWLTL) in the center of local streets for the purpose of BRT during peak hours. However, a TWLTL can be used in two ways for this purpose: directly as a median BRT lane and as a reversible general traffic lane (so that ...
You should also wait to enter a center turn lane. If you enter a two-way left turn too soon, you may obstruct vehicles from the other direction. Many states have laws that specify how far you can travel in this lane to prepare for a left turn. Unless state laws say otherwise, driving...
The presented theoretical concept can be extended to include the consequences of a short left-turn pocket on major streets and the corresponding capacities of the major streets with shared short lanes. Equations are derived for calculating the influence of the length of the left-turn pocket on ...

A "road diet" entails converting a four-lane undivided roadway to a two-lane roadway plus a two-way left turn lane by removing a travel lane in each direct... JA Rosales,KK Knapp 被引量: 13发表: 2005年 A study on passing - overtaking characteristics and level of service of heterogeneou...
Throughout the overtaking behavior, it is assumed that the leading vehicle and the oncoming vehicle are traveling at their respective speeds in their respective lanes, independent of the position, speed, and acceleration of the passing vehicle. While this may be considered a bit too conservative, ...
(g) a first traveled way left turn ramp forming a distinct section, being disposed at a predetermined first point along the right side of said first traveled way, crossing under said third and fourth traveled ways, crossing over said first and second traveled ways, and joining the right side...
The center lines of the east–west and north–south lanes at the intersection are labeled as 𝐿𝐶1LC1 and 𝐿𝐶2LC2, respectively; 𝐿𝑆1LS1 through 𝐿𝑆4LS4 represent the stop line at the intersection; and (𝑥′,𝑦′)(x′,y′) is the confluence point of the two ...
