MIXED TRAFFIC

The BRT would travel with general traffic. It would not have lanes dedicated for its use.

TWO MEDIAN BRT LANES

Two lanes located in the center of the roadway would be dedicated for use by the BRT, and may be physically separated from traffic by a raised curb or median. Median BRT lanes would minimize conflicts with general traffic and allow the BRT to operate faster and more reliably. However, the BRT lanes would interact with other traffic at intersecting cross streets. To avoid conflicts, general traffic could only make left turns at signalized intersections.

ONE MEDIAN BRT LANE (BI-DIRECTIONAL)

BRT vehicles traveling in both directions would share a single dedicated lane in the center of the roadway. Since the BRT travels within this one lane in both directions, passing zones would be created so BRT vehicles moving in opposite directions would not conflict with each other.

ONE MEDIAN BRT LANE (FIXED OR REVERSIBLE)

Two types of BRT operations are being considered in these locations: fixed- and reversible-direction operations. In fixed-direction operations, a single median BRT lane would be used solely by the southbound BRT. The northbound BRT would travel in mixed traffic. In reversible-direction operations, the direction of the BRT in the one median lane would vary depending on the time of day. BRT vehicles traveling in the peak direction would use the median BRT lane and BRT vehicles traveling in the non-peak direction would be in mixed traffic.

ONE CURB BRT LANE (FIXED SOUTHBOUND)

The lane adjacent to the curb along southbound MD 355 would be used exclusively by the BRT, local buses and right-turning vehicles. BRT vehicles heading northbound on MD 355 would travel with general traffic.

ONE CURB BRT LANE (PEAK DIRECTION ONLY)

A curb BRT lane would be created by re-purposing the peak direction curb lane to accommodate BRT buses, local buses, and right-turning vehicles. The two center general traffic lanes would have a reversible operation with different AM/PM lane configurations. BRT vehicles heading in the off-peak direction would travel with general traffic.

TWO CURB BRT LANES

The two lanes adjacent to the curb (one on each side of the roadway) would be used exclusively by the BRT, local buses and right-turning vehicles.

TRANSIT SIGNAL PRIORITY

Transit Signal Priority (TSP) would give priority to BRT vehicles when certain conditions are met by either extending a green light or shortening a red light to allow an approaching BRT to pass through the intersection. TSP was implemented on the MD 355 corridor between the Lakeforest Transit Center and Medical Center as part of the new Ride On Extra service in October 2017.

QUEUE JUMP

A queue jump is a short section of roadway widening on an approach to an intersection designated for exclusive use of the BRT. A queue jump allows BRT vehicles to bypass congestion or delays at intersections. In most applications, queue jumps are used in conjunction with TSP to allow vehicles to enter an intersection with a special signal ahead of other vehicles.

RELIABLE Frequent service, dedicated lanes, and green light priority signaling keep BRT vehicles moving.

EFFICIENT One BRT vehicle can take up to 90 cars off the road, making our transportation network more efficient and your commute easier.

CLEAN BRT reduces harmful greenhouse gas emissions, making our air cleaner.

COMFORTABLE New BRT stations will feature real-time travel info and provide a place for you to wait comfortably and pay your fare before boarding.

COST-EFFECTIVE You can save money by riding BRT instead of driving a car.
