A. Problem Statement Transit serving the downtown core is reaching the limits of its practical capacity today, and, with the GTAH continuing to grow and develop, the need for improvements to existing transit service is clear. Both Metrolinx (in the Regional Transportation Plan) the City of Toronto and the Toronto Transit Commission (TTC) have identified a number of potential infrastructure, operational and policy improvements to provide additional transit capacity into, and within Downtown Toronto. However, recent studies have identified the need to look at additional opportunities to enhance rapid transit, particularly into the downtown area. Within the downtown core, the existing population of 71,000 is projected to increase by 83% to 130,000 by 2031. During the same period, employment is expected to grow from the current 315,000 to 404,000 (28% increase) by 2031. In addition, the City’s plans call for significant growth in areas immediately adjacent to the downtown core, notably in the Waterfront and the “shoulder” areas east and west of the downtown. Significant growth is also forecast in the remainder of the City and in the Greater Toronto Area. This is expected to further increase demand coming into and out of the Downtown Core. In total, future transit demand into the downtown core is expected to increase by 55% from 155,000 to 236,000 morning peak period trips. To illustrate existing and future 2031 transit capacity deficiencies, forecasts of hourly ridership have been compared to estimated hourly passenger capacity for all transit lines inbound to the downtown core. Table A-1 summarizes existing demand, capacity and deficiencies for rapid transit lines inbound to the downtown core. The Volume/Capacity ratio (V/C) is a ratio of transit demand to transit capacity. A V/C ratio around 1.00 indicates that the transit facility is at capacity. A V/C ratio less than 1.00 indicates demand is less than capacity, while a V/C ratio higher than 1.00 represents a situation where transit demand exceeds capacity.

Streetcar routes (not shown above) east and west of the downtown are similarly constrained. To address these deficiencies, and to manage growth, the TTC is implementing a range of capacity improvements to the existing rapid transit network over the next several years and this expanded capacity is a critical element in ensuring the continued health and vitality of the downtown area. In addition, there are also significant planned improvements to GO Rail services consistent with Metrolinx’s Regional Transportation Plan. The project team and Metrolinx staff jointly developed a “2031 Reference Network” reflecting the committed and planned rapid transit improvements expected to be implemented by 2031. Even with the currently-planned GO and TTC improvements, the Yonge Subway line and much of the GO Rail network will be at, or over, capacity for trips into the Downtown Toronto area during the peak periods in 2031. The most serious capacity issues are related to long- and medium-distance trips from the east and north, as illustrated in Table A-2.

The Yonge Subway will be approaching capacity – Assuming a significant increase in the Yonge Subway capacity with the implementation of Toronto Rocket Cars and Automatic Train Control (ATC) signalling systems, the Yonge Subway Line will still be approaching capacity. Capacity will continue to be constrained south of Bloor-Yonge Station. There will be little spare capacity on the Yonge Subway to accommodate further increases in transit ridership beyond the projections shown in Table A-2. In addition, if transit passengers are unable to ride the Barrie-Bradford and Stouffville GO lines because of inadequate future capacity, some of these riders will want to divert to the Yonge-University Subway line, adding further demand to the line and exacerbating its potential capacity problems. There is an EA approved extension of the Yonge Subway from Finch Avenue to Highway 7 currently in the Metrolinx Move Ontario 2020 plan. Even with the planned improvements, projected demands on the Yonge subway associated with the Yonge Extension scenario will result in ridership exceeding the capacity of the Yonge Subway line. Some GO lines will have insufficient capacity – Many of the GO Rail lines to the downtown will be at capacity, even with improvements currently planned by Metrolinx. September 2012 iii From the north, passenger demand is forecast to exceed the capacities of the Barrie-Bradford and Stouffville GO lines. Ridership on the Lakeshore East GO line is estimated to significantly exceed the future capacity of the line. Although the analysis indicates the Georgetown and Milton GO lines will be over capacity, some of their ridership can be accommodated by the Lakeshore West GO line which will have spare capacity. Bloor-Yonge Station has limited capacity for passenger transfers – Bloor-Yonge station is currently a key transfer point in the subway network. Today, virtually all demand from the east and significant demand from the west on the Bloor-Danforth line destined to the Downtown Core transfers at Bloor-Yonge station, resulting in very large transfer volumes at this station. The situation is exacerbated by full trains on the Yonge Subway resulting in increased dwell times on the station platforms. With the currently-planned rapid transit network and services, by 2031 the critical passenger transfers movements at Bloor-Yonge Station are expected to increase by 45% and will require substantial improvements to be made at Bloor-Yonge Station to increase passenger capacity. TTC Union Station and other downtown subway stations – Although the TTC is implementing improvements to Union (subway) Station, the significant growth in passenger flows at this and other downtown subway stations (such as King Station) may near or exceed station capacities in the future during peak periods. Deteriorating quality of surface transit services – Surface services can provide adequate capacity to accommodate the forecast demand from the “shoulder” areas adjacent to the downtown only if the current quality of service provided on surface routes in mixed traffic can be maintained and improved.

  • Routing Changes - Junction Area Study Update
    For Action Routing Changes - Junction Area Study Update Date: July 10, 2018 To: TTC Board From: Chief Customer Officer Summary The TTC bus network is very mature. In order to ensure that the network continues to reflect the way our customers travel across the city, staff has developed a program to review different segments of the city over time. This report provides an update on the status of the Junction Area Study. The objective of the study is to improve transit travel for customers by restructuring the bus route network in the Junction Area. In spring 2017, the TTC began the study with a customer survey to better understand customer travel patterns in the Junction Area. Feedback was also collected on existing services to identify key concerns for customers. Three key issues were identified: • No continuous transit service along Dundas Street West between Dundas West Station and Kipling Station; • No continuous transit service along St Clair Avenue West between Gunn's Loop (Weston Road) and Scarlett Road; and, • Need to extend the 80 Queensway from its current eastern terminus at Humber Loop to Keele Station via Parkside Drive in the late evening and on Sundays and holidays. Based on this feedback, staff prepared and proposed a preliminary transit network to reflect the data collected and address concerns raised by customers. The new transit network includes a number of service proposals that include restructuring and rationalizing existing services and improving periods of service on routes. In May 2018, the TTC held public information sessions at Runnymede, High Park, and Dundas West stations, and Gunn’s Loop to share the proposed transit network with customers and to collect feedback on the proposals.

  • Draft Delineations for the Protected Major Transit Station Areas Within the Downtown Secondary Plan and Draft Citywide MTSA Policy Directions
    REPORT FOR ACTION Draft Delineations for the Protected Major Transit Station Areas within the Downtown Secondary Plan and Draft Citywide MTSA Policy Directions Date: March 30, 2021 To: Planning and Housing Committee From: Chief Planner and Executive Director, City Planning Wards: Ward 10 - Spadina-Fort York; Ward 11 - University Rosedale and Ward 13 - Toronto Centre SUMMARY In June 2020, City Planning initiated the Growth Plan Conformity and Municipal Comprehensive Review ("the MCR") which includes the delineation of 180+ Major Transit Station Areas (MTSAs) to meet Provincial intensification requirements by July 2022. The introduction of Protected Major Transit Station Areas (PMTSAs) is part of the MCR. An equity lens is being applied to this work program that prioritizes the delineation of PMTSAs to enable the implementation of inclusionary zoning as an affordable housing tool, where market conditions could support it. This report presents the policy approach for advancing the implementation of Major Transit Station Areas and Protected Major Transit Station Areas, and the proposed delineations within the Downtown Secondary Plan. This report is intended as the basis for consultation of the draft Official Plan Amendment (OPA) that includes 16 Site and Area Specific Policies (SASPs) that delineate Protected Major Transit Station Areas (PMTSAs) within the Downtown Secondary Plan area. The draft policy directions for the introduction of a new Chapter 8 of the Official Plan will be refined following consultation and brought forward as part of the final Official Plan Amendment. The 16 PMTSA delineations included in this draft OPA would implement the Minister approved Downtown Plan and address the requirements of the A Place to Grow: Growth Plan for the Greater Golden Horseshoe (2020) (the "Growth Plan") and Section 16(15) of the Planning Act.

  • Rapid Transit in Toronto Levyrapidtransit.Ca TABLE of CONTENTS
    The Neptis Foundation has collaborated with Edward J. Levy to publish this history of rapid transit proposals for the City of Toronto. Given Neptis’s focus on regional issues, we have supported Levy’s work because it demon- strates clearly that regional rapid transit cannot function eff ectively without a well-designed network at the core of the region. Toronto does not yet have such a network, as you will discover through the maps and historical photographs in this interactive web-book. We hope the material will contribute to ongoing debates on the need to create such a network. This web-book would not been produced without the vital eff orts of Philippa Campsie and Brent Gilliard, who have worked with Mr. Levy over two years to organize, edit, and present the volumes of text and illustrations. 1 Rapid Transit in Toronto levyrapidtransit.ca TABLE OF CONTENTS 6 INTRODUCTION 7 About this Book 9 Edward J.

    New Station Initial Business Case Milton-Trafalgar Final October 2020 New Station Initial Business Case Milton-Trafalgar Final October 2020 Contents Introduction 1 The Case for Change 4 Investment Option 12 Strategic Case 18 Economic Case 31 Financial Case 37 Deliverability and Operations Case 41 Business Case Summary 45 iv Executive Summary Introduction The Town of Milton in association with a landowner’s group (the Proponent) approached Metrolinx to assess the opportunity to develop a new GO rail station on the south side of the Milton Corridor, west of Trafalgar Road. This market-driven initiative assumes the proposed station would be planned and paid for by the private sector. Once built, the station would be transferred to Metrolinx who would own and operate it. The proposed station location is on undeveloped land, at the heart of both the Trafalgar Corridor and Agerton Employment Secondary Plan Areas studied by the Town of Milton in 2017. As such, the project offers the Town of Milton the opportunity to realize an attractive and vibrant transit-oriented community that has the potential to benefit the entire region. Option for Analysis This Initial Business Case (IBC) assesses a single option for the proposed station. The opening-day concept plan includes one new side platform to the north of the corridor, with protection for a future second platform to the south. The site includes 1,000 parking spots, a passenger pick-up/drop-off area (40 wait spaces, 10 load spaces), bicycle parking (128 covered spaces, 64 secured spaces) and a bus loop including 11 sawtooth bus bays.

  • Bus Bridging Decision-Support Toolkit: Optimization Framework and Policy Analysis
    Bus Bridging Decision-Support Toolkit: Optimization Framework and Policy Analysis by Alaa Itani A thesis submitted in conformity with the requirements for the degree of Master of Applied Science Department of Civil and Mineral Engineering University of Toronto © Copyright by Alaa Itani 2019 Bus Bridging Decision-Support Toolkit: Optimization Framework and Policy Analysis Alaa Itani Master of Applied Science Department of Civil and Mineral Engineering University of Toronto 2019 Abstract Bus Bridging is the strategy most commonly applied in responding to rail service interruptions in North America and Europe. In determining the required number of buses and source routes, most transit agencies rely on ad-hoc approaches based on operational experience and constraints, which can lead to extensive delays and queue build-ups at affected stations. This thesis developed an optimization model, to determine the optimal number of shuttle buses and route allocation which minimize the overall subway and bus riders delay. The generated optimal solutions are sensitive to bus bay capacity constraints along the shuttle service corridor. The optimization model is integrated with a previously developed simulation tool that tracks the evolution of system queues and delays throughout the bus bridging process. A set of bus bridging policy guidelines were developed based on further analysis of the optimization model outputs using a Classification and Regression Tree (CART) model. ii Acknowledgments First, I would like to thank my parents and for their continuous support and trust in my abilities. Although they were thousands of miles away, they were always supportive, I couldn’t have made it here without their presence.

  • Mobility Hubs December 2008
    Mobility Hubs December 2008 1. Introduction This is one in a series of backgrounders that have been produced by Metrolinx to provide further explanation and clarification on the policies and directions of the Regional Transportation Plan (RTP). The RTP is available for downloading at www.metrolinx.com. This backgrounder should be read as an accompaniment to Strategy 7 of the RTP. It is intended to provide additional detail on the mobility hub policies of the RTP and clarification of the terms and definitions used in the RTP with respect to mobility hubs. Metrolinx wishes to acknowledge the invaluable contribution of Urban Strategies Inc. and IBI Group to the preparation of this backgrounder. 2. What is a Mobility Hub? The mobility hub policies of the RTP build on the overall policy framework established in the Growth Plan for the Greater Golden Horseshoe, particularly those related to major transit station areas. The Growth Plan defines major transit station areas as the area within a 500m radius (10 minute walk) of any existing or planned higher order transit station within a settlement area or around a major bus depot in an urban core. Major transit station areas that are particularly significant for the regional rapid transit system are recognized as mobility hubs in the RTP. Mobility hubs are major transit station areas with significant levels of transit service planned for them in the RTP, high development potential, and a critical function in the regional transportation system as major trip generators. They are places of connectivity where different modes of transportation — from walking to high- speed rail — come together seamlessly and where there is an intensive concentration of employment, living, shopping and/or recreation.
