BASIS OF ARCHITECTURAL

DESIGN:

6 UNIQUE STATION TYPES BASED ON A SINGLE PROTOTYPE

System-wide Architecture

16

Goal: Create a system-wide architectural scheme for stations that symbolizes the premium BRT project that the CCT is by creating an image for the system while also establishing the stations as amenities for the communities they serve.

Goal: Create a system-wide architectural scheme for stations that symbolizes the premium BRT project that the CCT is by creating an image for the system while also establishing the stations as amenities for the communities they serve.

Operations Planning

26

Operations Planning

• Operations Planning

– Required buses per hour

– Bus fleet size

27

Operations Planning • Step 1 – Final Policy Guidelines

– Vehicle type • 60’ articulated vehicle with 60 seats • Diesel-Electric Hybrid

– Acceptable maximum passenger load • 60 seated/30 standing passengers per vehicle (industry standard)

– Services utilizing transitway • Only CCT branded vehicles

– Two route patterns – CCT Direct and CCT via USG

– No proposed changes to RideOn, WMATA, or local shuttle Networks • Ongoing coordination with agencies

– Elements impacting CCT operations • Fare collection approach • Transit Signal Priority • Vehicle configuration

2020 - Station-to-Station Link Passenger Load AM Peak Hour - Outbound

AM Peak NB Passenger Load by Link

Operations Planning (cont.)

• Step 2 – Calculate required # of buses per hour

– Ridership forecast - determine maximum passenger load location and hour

• AM Peak

• Mid-Day

– Maximum load will dictate the required number of buses per hour

33

Operations Planning (cont.)

• Step 2 – cont.

– Maximum Load – 893

• Northbound between East Gaither and West Gaither

– Required # of Bus Arrivals

• 893/90 passengers (allowable load) = 9.92 = 10 buses on CCT Direct required per hour to meet demand – Frequency = 60/10 = a bus every 6 minutes
