Metro Rail Design Criteria Section 10 Operations
METRO RAIL DESIGN CRITERIA SECTION 10 OPERATIONS METRO RAIL DESIGN CRITERIA SECTION 10 / OPERATIONS TABLE OF CONTENTS 10.1 INTRODUCTION 1 10.2 DEFINITIONS 1 10.3 OPERATIONS AND MAINTENANCE PLAN 5 Metro Baseline 10- i Re-baseline: 06/15/10 METRO RAIL DESIGN CRITERIA SECTION 10 / OPERATIONS OPERATIONS 10.1 INTRODUCTION Transit Operations include such activities as scheduling, crew rostering, running and supervision of revenue trains and vehicles, fare collection, system security and system maintenance. This section describes the basic system wide operating and maintenance philosophies and methodologies set forth for the Metro Rail Projects, which shall be used by designer in preparation of an Operations and Maintenance Plan. An initial Operations and Maintenance Plan (OMP) is developed during the environmental phase and is based on ridership forecasts produced during this early planning phase of a project. From this initial Operations and Maintenance plan, headways are established that are to be evaluated by a rail operations simulation upon which design and operating headways can be established to confirm operational goals for light and heavy rail systems. The Operations and Maintenance Plan shall be developed in order to design effective, efficient and responsive transit system. The operations criteria and requirements established herein represent Metro’s Rail Operating Requirements / Criteria applicable to all rail projects and form the basis for the project-specific operational design decisions. They shall be utilized by designer during preparation of Operations and Maintenance Plan. Any proposed deviation to Design Criteria cited herein shall be approved by Metro, as represented by the Change Control Board, consisting of management responsible for project construction, engineering and management, as well as daily rail operations, planning, systems and vehicle maintenance with appropriate technical expertise and understanding. -

Headway Adherence. Detection and Reduction of the Bus Bunching Effect
HEADWAY ADHERENCE. DETECTION AND REDUCTION OF THE BUS BUNCHING EFFECT Josep Mension Camps Director Central Services and Deputy Chief Officer of Bus Network. Transports Metropolitans de Barcelona (TMB). Miquel Estrada Romeu Associate Professor. Universitat Politècnica de Catalunya- BarcelonaTECH. 1. INTRODUCTION Transit systems should provide a good performance to compete against the wide usage of cars in metropolitan areas. The level of service of these systems relies on a proper temporal and spatial coverage provision (high frequencies, low stop spacings) as well as significant regularity and comfort. In this way, bus systems in densely populated cities usually operate at short headways (10 minutes or less). However, in these busy routes, any delay suffered by a single bus is propagated to the whole bus fleet. This fact causes vehicle bunching and unstable time-headways. In real bus lines, we usually see that two or more vehicles arrive together or in close succession, followed by a long gap between them. There are many sources of potential external disruptions in the service of one bus: illegal parking in the bus lane, failure in the doors opening system, traffic jams, etc. However, some intrinsic characteristics of transit systems and traffic management may also induce delays at specific vehicles such as traffic signal coordination and irregular passenger arrivals at stops. These facts make the bus motion unstable. Therefore, bus bunching is a common problem in the real operation of buses all over the world that must be addressed. The crucial issue is that bus bunching has a great impact on both users and agency cost. From a passenger perspective, the bus bunching phenomena increases the travel time of passengers (riding and waiting time) and worsens the vehicle occupancy. -
Making Headway, Capital Investments to Keep Transit Moving
CAPITAL INVESTMENT PLAN Making Headway Capital Investments to Keep Transit Moving 2019–2033 headway (/ˈhed wā/) noun 1. forward movement or progress, especially when the way is difficult. 2. the average interval between trains, streetcars, or buses. The shorter the headway, the more passengers carried per hour. Making Headway — Capital Investments to Keep Transit Moving January 2019 From the Chief Executive Officer In January 2018, the TTC published a new Corporate Plan that clearly laid out our priorities for the next five years. At the top of the list was transforming for financial sustainability. “Fiscal sustainability,” we said, “depends on our ability to fund what the TTC is being asked to deliver over the long term.” We committed to providing better budget information for improved long-term decision-making. Over the past 12 months, we have undertaken a massive, multi-department review of all of our assets. The result is this Capital Investment Plan. Toronto’s transit system is hailed as among the most multi- modal systems in the world, with seamless integration between buses, streetcars, Wheel-Trans and the subway. The TTC’s interdependent network of fleet, track, power, maintenance and other infrastructure moves more than half a billion people annually. Funding for critical maintenance and system improvements is necessary. Projects that have been approved are still awaiting funding. Line 2 Capacity Enhancement is unfunded. Buses past 2021 are unfunded. The expansion of Bloor-Yonge Station, which is needed to accommodate ridership growth even before planned transit expansion, is unfunded. The TTC Way, which was introduced in our Corporate Plan, establishes clear guidelines for how we at the TTC work with each other, with customers and with our partners, including our funding partners. -

IMechE 2016 Reprints and permissions: interface of rail vehicles for the sagepub.co.uk/journalsPermissions.nav DOI: 10.1177/0954409716684266 infrastructure of light rail, heavy rail, journals.sagepub.com/home/pif and commuter rail transit Xiao Lin, J Riley Edwards, Marcus S Dersch, Thomas A Roadcap and Conrad Ruppert Jr Abstract The type and magnitude of loads that pass through the track superstructure have a great impact on both the design and the performance of the concrete crossties and fastening systems. To date, the majority of North American research that focus on quantifying the rail infrastructure loading conditions has been conducted on heavy-haul freight railroads. However, the results and recommendations of these studies may not be applicable to the rail transit industry due to a variety of factors. Unlike the freight railroads, which have standardized maximum gross rail loads and superstructure design practices for vehicles, the rail transit industry is home to a significant variety of vehicle and infrastructure designs. Some of the current transit infrastructure design practices, which were established decades ago, need to be updated with respect to the current loading environment, infrastructure types, and understanding of the component and system-level behavior. This study focuses on quantifying the current load environment for light rail, heavy rail, and commuter rail transit infrastructure in the United States. As an initial phase of this study, researchers at the University of Illinois at Urbana-Champaign (UIUC) have conducted a literature review of different metrics, which is used to evaluate the static, dynamic, impact, and rail seat loads for the rail transit infrastructure. -

A HEADWAY CONTROL STRATEGY FOR RECOVERING FROM TRANSIT VEHICLE DELAYS Peter G. Furth I ASCE Transportation Congress, San Diego October 24, 1995 Abstract Suppose a subway train is delayed due to, say, a medical emergency. What adjustments to the following trains' itineraries should be made in order for the schedule to recover from this initial delay? An optimization framework for finding the optimal schedule adjustments is devised. It accounts for the impact of those adjustments on ride time and waiting time, and has as its objective the minimization of total passenger time. Optimality conditions and a solution algorithm are developed. Realistic constraints such as a safety headway, vehicle capacity, and maximum delay at the start ofthe line are explicitly incorporated. Examples illustrate the main features of the optimal adjustment pattern. After adjustment, a train will follow its leader by the scheduled headway minus an amount called that train's schedule recovery. Because the optimal solution involves a tradeoff between minimizing the ride time impact, which is accomplished by immediately recovering from the initial delay, and the wait time impact, which is minimized by spreading the recovery over a large number of following trains, the optimal recovery pattern lies between these two extremes. In general, there is an S-shaped pattern to the recovery distribution: large recovery for the first one or two trains following the initially delayed train, then rapidly diminishing recoveries per train, and finally small recoveries for the last few trains. The location of the initial delay influences the recovery pattern. Delays that occur on a boarding section, where many waiting passengers will be affected, tend to benefit most from an optimal recovery as opposed to a policy of immediate recovery. -

Review of the G Line
Review of the G Line ,. July 10, 2013 NYC Transit G Line Review Executive Summary Executive Summary The attached report provides a comprehensive review of operations on the G line. Based on NYC Transit’s standard measures of On-Time Performance and Wait Assessment, the G performs well relative to the average subway line. At the same time, the G differs from other NYC Transit subway lines because the route is relatively short and never enters Manhattan, and thus serves primarily as a feeder/distributor with most riders transferring at least once before reaching their destinations. This review identifies a number of opportunities to improve operations on the G line, with recommendations chiefly intended to provide more even train headways and passenger loading, as well as to improve customer communication. Key Findings: While G ridership has grown significantly in recent years, it still remains relatively low compared to the rest of the system, and average passenger loads on the G are within service guidelines during both peak and off-peak hours. Scheduling the G train around the busier and more frequent F train causes uneven headways and passenger loads on the G, most significantly during the afternoon peak period, when G service is scheduled at the minimum guideline frequency of 6 trains per hour (an average 10-minute headway). G riders make twice as many transfers as the average subway rider; this high transfer rate is inconvenient for customers who must wait for multiple trains. Trains shorter than the platform length cause uncertainty about where the G train stops, contributing to uneven passenger loads.
