Dual Rated Speeds Escalator in Rapid Transit System with Extended Ramping Up and Down KC Gan, LF Cai, SC Cheah, Hadi Wijaya, Melvyn Thong Land Transport Authority, Singapore Keywords: Dual rated speeds, automatic switching, rapid transit system, acceleration, ramping up, ramping down, vibration, jerkiness. Abstract. To cater for different needs of escalator operating speeds in rapid transit systems (i.e. higher rated speed of 0.75m/s during peak hours is for effective discharging of passengers while slower rated speed of 0.50m/s during off-peak hours is for elderly passengers), we have introduced the dual rated speed escalator. Conventionally, the switching between 2 rated speeds can be done either manually through a key switch or automatically when no passengers are detected on the escalators at pre-set timing. However, there is a possibility of not being able to change speed if there are constant passengers coming into the rapid transit station, taking the escalators. Therefore, this shortcoming will be overcome by setting up a schedule timetable to do the safe switching of escalator rated speeds with passengers riding on the escalators with extended ramping up and down without comprising any safety requirements. This paper presents the case studies conducted on an existing station where a performance–based approach was adopted. The timing for the speed ramping up/down between the 2 rated speeds has been increased to 30 seconds in order to reduce the acceleration which results in minimizing the acceleration (vibration) and the rate of change of this acceleration (jerk). The objective is to ensure that the passenger’s perception are imperceptible and do not experience any abnormal and sudden change of vibration and jerk during the switching of dual rated speeds with extended ramping up and down. -
Transit Service Design Guidelines
Transit Service Design Guidelines Department of Rail and Public Transportation November 2008 Transit Service Design Guidelines Why were these guidelines for new transit service developed? In FY2008 alone, six communities in Virginia contacted the Virginia Department of Rail and Public Transportation about starting new transit service in their community. They and many other communities throughout Virginia are interested in learning how new transit services can enhance travel choices and mobility and help to achieve other goals, such as quality of life, economic opportunity, and environmental quality. They have heard about or seen successful transit systems in other parts of the state, the nation, or the world, and wonder how similar systems might serve their communities. They need objective and understandable information about transit and whether it might be appropriate for them. These guidelines will help local governments, transit providers and citizens better understand the types of transit systems and services that are available to meet community and regional transportation needs. The guidelines also help the Virginia Department of Rail and Public Transportation (DRPT) in making recommendations to the Commonwealth Transportation Board for transit investments, by 1) providing information on the types of systems or services that are best matched to community needs and local land use decisions, and 2) ensuring that resources are used effectively to achieve local, regional, and Commonwealth goals. Who were these guidelines developed for? These guidelines are intended for three different audiences: local governments, transit providers and citizens. Therefore, some will choose to read the entire document while others may only be interested in certain sections. -

The findings suggest that some BRT design features – such as center lane configurations, left turn prohibitions, and signalized mid-block pedestrian crossings with refuge islands – can significantly improve safety on the corridors where BRTs operate. However, there is still a gap in knowledge about how the different safety features might impact the operational performance of the BRT. -
Comparison Between Bus Rapid Transit and Light-Rail Transit Systems: a Multi-Criteria Decision Analysis Approach
Urban Transport XXIII 143 COMPARISON BETWEEN BUS RAPID TRANSIT AND LIGHT-RAIL TRANSIT SYSTEMS: A MULTI-CRITERIA DECISION ANALYSIS APPROACH MARÍA EUGENIA LÓPEZ LAMBAS1, NADIA GIUFFRIDA2, MATTEO IGNACCOLO2 & GIUSEPPE INTURRI2 1TRANSyT, Transport Research Centre, Universidad Politécnica de Madrid, Spain 2Department of Civil Engineering and Architecture (DICAR), University of Catania, Italy ABSTRACT The construction choice between two different transport systems in urban areas, as in the case of Light-Rail Transit (LRT) and Bus Rapid Transit (BRT) solutions, is often performed on the basis of cost-benefit analysis and geometrical constraints due to the available space for the infrastructure. Classical economic analysis techniques are often unable to take into account some of the non-monetary parameters which have a huge impact on the final result of the choice, since they often include social acceptance and sustainability aspects. The application of Multi-Criteria Decision Analysis (MCDA) techniques can aid decision makers in the selection process, with the possibility to compare non-homogeneous criteria, both qualitative and quantitative, and allowing the generation of an objective ranking of the different alternatives. The coupling of MCDA and Geographic Information System (GIS) environments also permits an easier and faster analysis of spatial parameters, and a clearer representation of indicator comparisons. Based on these assumptions, a LRT and BRT system will be analysed according to their own transportation, economic, social and environmental impacts as a hypothetical exercise; moreover, through the use of MCDA techniques a global score for both systems will be determined, in order to allow for a fully comprehensive comparison.

Bus Rapid Transit As Formalization: Accessibility Impacts of Transport Reform in Cape Town, South Africa
Bus rapid transit as formalization: Accessibility impacts of transport reform in Cape Town, South Africa by Lisa Rayle A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in City & Regional Planning in the Graduate Division of the University of California, Berkeley Committee in charge: Associate Professor Daniel Chatman, Chair Professor Emeritus Robert Cervero Professor Emerita Elizabeth Deakin Associate Professor Alison Post Fall 2017 Bus rapid transit as formalization: Accessibility impacts of transport reform in Cape Town, South Africa Copyright 2017 by Lisa Rayle 1 Abstract Bus rapid transit as formalization: Accessibility impacts of transport reform in Cape Town, South Africa by Lisa Rayle Doctor of Philosophy in City & Regional Planning University of California, Berkeley Associate Professor Daniel Chatman, Chair Many cities worldwide are introducing bus rapid transit (BRT) into contexts where informal transport modes serve a substantial part of the public transport market. These BRT initia- tives are intended, among other goals, to formalize existing transport systems and to improve accessibility. However, the extent to which BRT reforms actually improve residents' ability to reach activities remains in question. In this dissertation, I contribute to the empirical and theoretical literature on informal transport by investigating how BRT reform has impacted accessibility for residents of Cape Town, South Africa. How have Cape Town's transport reforms affected accessibility and its distribution amongst different population groups? Why have reforms had these effects? I address these questions using three methods: (1) an accessibility index computed using a transport network model, (2) a difference-in-difference approach using intercept survey data, and (3) interviews with users and stakeholders. -
Passenger Rail Primer
Passenger Rail Primer Thurston Passenger Rail Workgroup November 2005 Passenger Rail Characteristics This document is intended as a primer introducing and familiarizing the reader with the basic definitions of passenger rail and providing a comparison of common transit services in 2005. It was developed to facilitate a discussion of passenger rail and other transit options in the Thurston Region, in preparation of a regional rail plan. In the next section, Passenger Rail Overview, the fundamental characteristics of light rail, commuter rail and intercity rail are covered. Complementary and Alternative Transit Options (primarily common bus transit choices) provides a wider transit context within which the passenger rail modes coordinate and compete. After investigating transit options individually, they are compared and contrasted in a chart of their characteristics, Summarizing the Continuum of Services. Other Rail Transit Technologies provides a brief overview of less extensively used rail options and the Appendices provide additional details and information. Additional resources the reader may want to consult include: • The American Public Transportation Association (APTA) website at www.apta.com • The Victoria Transportation Policy Institute (VTPI) website at www.vtpi.org • Bureau of Transportation Statistics (BTS) website at www.bts.gov Passenger Rail Overview Introduction Passenger rail modes may be distinguished from one another based on a variety of characteristics – level of service, technology, right-of-way and operations. These characteristics are discussed in more detail in the other sections of this chapter. Like other transit services, however, in the most basic sense passenger rail modes break down by three distinct geographies – local, regional, and statewide or interstate. -
