Going to revive a dead thread.
Translink has just issued an RFP for conceptual design - Phase 2 of Commercial Broadway, interesting tidbits, like the longterm planning of the B-Line and no mention of the UBC line. I agree with parts of it, but feel some of it is a little over the top. Anyways I took the time to cut out the juicier tidbits and I've provided links to the whole thing for the info junkies.
Quote:
1.2 Approximately 150,000 people use Commercial-Broadway Station on a typical weekday, making it the busiest station in the entire Metro Vancouver transit network. Connections between the Expo Line, the Millennium Line, the 99 B-Line express bus to UBC and other local bus routes all happen at this location. The station‟s evolution, however, has occurred incrementally, on constrained sites, and with key functional elements designed in isolation of each other. This has resulted in severe congestion during the morning
peak, with long queues at key station “choke points” on an almost daily basis.
1.3 Expo Line ridership is growing at over 4% per year and at a greater rate than population growth due to:
(a) The increasing shift away from private automobile use;
(b) Improved connecting bus services, including higher frequencies on existing routes and new routes being added;
(c) Increased system ridership capacity provided by additional SkyTrain cars; and
(d) Development and densification around the Expo Line stations.
1.4 As ridership grows and places increased demand on the system, particularly its major transfer points, the crowding at Commercial-Broadway Station in its current configuration will worsen. This may dissuade new riders from using transit and could potentially result in current transit users choosing to return to private automobiles for their daily commute. TransLink and Provincial plans both call for an increase in transit mode share in Metro Vancouver, and in order to achieve this, additional capacity must be added to the system.
1.5 Increasing the number of SkyTrain vehicles will help address the overall system crowding, but the benefit of investment in new trains will not be fully realized without upgrades to the most heavily used Expo Line stations.
1.9 Despite the success of the Phase 1 improvements, a number of passenger flow and capacity issues within Commercial-Broadway Station still need to be addressed. Transfers between the Millennium Line (Commercial Station) and Expo Line (Broadway Station) are heavy during peak periods, and the current vertical circulation configuration generates significant queuing following the arrival of a train. It is anticipated that the situation will become further exacerbated over time, as passenger demand continues to increase. The primary circulation issues are:
(a) The vertical access points between the North Concourse (Commercial Station) and the Broadway passerelle;
(b) Platform crowding at Broadway Station, although improved, is anticipated to become severe again within the short- to medium-term, as ridership continues to increase and new rapid transit lines are added to the system; and
(c) Congestion due to conflicts between various passenger flow directions, particularly at the bottom of the escalators in the North Concourse.
2.3 The following issues were identified at Commercial-Broadway Station in the Expo Line Station Review (TransLink, 2007) and the Commercial-Broadway Station Capacity Analysis (VIA Architecture, 2007):
(a) Expo Line Platform Congestion
1. Despite the recent increase in train capacity, with the addition of new vehicles, the Expo Line platform regularly experiences crowding during peak hours, although not to the same degree as before Phase 1 was completed. Passenger pass-ups still occur, which is a main contributor to platform crowding during peak hours. It is estimated that the platform capacity needs to be approximately doubled to alleviate congestion and provide an adequate level of service for waiting passengers.
2. Recent studies have indicated that an outboard platform to the east of Platform 3 may be the only viable solution. While desirable from a passenger capacity and flow perspective, this configuration creates several challenges, due to existing buildings abutting the east side of the station.
(b) Broadway Passerelle & Vertical Circulation Congestion
1. Approximately 65 to 70 percent of the passengers boarding and alighting at the Broadway Station platform travel to/from the North Concourse via the Broadway passerelle, which provides a connection to the Millennium Line and the #99 B-Line heading westbound to UBC. The throughput capacity of the Broadway passerelle and the vertical circulation elements which connect it to the North Concourse are therefore considered to be the most critical elements facilitating passenger flows. It is estimated that the vertical circulation capacity at this location must be doubled to relieve current congestion and provide long-term capacity to meet demand.
(c) #99 B-Line Queuing
1. The 99 B-Line carries 52,000 passengers on an average weekday during the school year and 1,950 passengers in the AM peak hour. The current bus stop waiting area was not designed to handle the current passenger volumes that the B-Line generates.
2. The queues for the #99 B-Line express bus route, which are significant during peak periods, currently have only partial weather protection and obstruct the sidewalk on the northeast corner of the street intersection of Commercial Drive and Broadway. The queues frequently spill into the North Concourse area, which already contains many other functions and activities including: large volume of passenger transfers from Commercial Station to Broadway Station, transfers from #99 B-Line to SkyTrain, retail shops and designated space for kiosk vendors. The eventual introduction of fare gates will create additional congestion and circulation challenges for the North Concourse and will likely require the B-Line queue to be re-routed.
Concept Design Confirmation Phase
1. Core functional elements of the station upgrade have been identified in the
preliminary concept studies done to date. In addition, TransLink has initiated a fare gates project which will see fare gates implemented system wide by January 2013. TransLink has retained a separate consultant team for the detailed design of the fare gates project and will be advising the Commercial-Broadway Station consultant team on the spatial and circulation requirements associated with fare gates. Likewise, TransLink has retained a separate Code Consultant, who is specialised in transit station-related code issues, and will be advising the Commercial-Broadway Station consultant team throughout the design process (in both project phases of this contract) through intermittent code reviews.
2. These core elements, together with the fare gates initiative, will be the basis for further evaluation in this stage of the project with the objective of yielding a confirmed, comprehensive conceptual strategy that addresses the needs identified for Commercial-Broadway Station. Alternate or optional considerations should be studied and documented if aspects of the core elements identified in the preliminary concept studies are deemed to compromise an effective fare gate location or configuration strategy or if they are deemed to compromise a more beneficial, comprehensive upgrade strategy. The core functional elements identified in the preliminary conceptual studies which require evaluation and confirmation include:
a. A new east outboard platform and associated vertical circulation as a well-integrated element of the Station.
b. Associated modifications related to the addition of a new east outboard platform including:
i. Modifications to the existing hoop trusses that currently terminate at the neighbouring party wall (west wall of Safeway). The existing trusses will likely need to be extended and affixed to the station structure differently than the existing configuration.
ii. Temporary provisions to support the existing hoop trusses during construction, once the party wall is removed, will need to be studied, evaluated and proposed.
iii. New roof over new east outboard platform for weather protection.
iv. New enclosure adjacent to the new east outboard platform for wind / weather protection and guardrail provisions.
3. Vertical circulation elements throughout the station including any opportunities and constraints related to the introduction of new vertical circulation to the existing station houses.
4. Integration of the future fare gates, specifically their associated location and configuration requirements with the comprehensive station upgrade strategy. This portion of the work will be done in close consultation with TransLink and the fare gates consultant team.
5. Provisions for #99 B-Line queuing – spatial allowance for line-ups, appropriate weather protection and integration with overall phase 2 upgrade strategy and existing, surrounding station
