  1. Fixed RouteQuality of Service

  2. Presentation Overview Learning objectives Performance points of view Quality of service factors Quality of service framework Quality of service measures Applications

  3. Learning Objectives • Gain an understanding of the different stakeholder perspectives that can be taken with respect to transit performance • Understand the key components of passengers’ perceptions of transit service quality • Be able to define quality of service (QOS) • Become familiar with the TCQSM’s approach to fixed-route QOS: • Framework • Service measures focused toward transit agencies • Multimodal level of service measure focused toward planning and engineering applications • Become familiar with potential applications of the manual’s QOS measures to real-world transportation planning and transit activities

  4. Changes from the 2nd Edition • Reorganized transit quality of service framework • Clearer guidance on performance measures that can be applied to stop, route/street segment, and system levels of analysis • Removed level of service (LOS) letters from QOS tables • Responding to transit agency concerns about being “graded” • Allows more or fewer service levels, as appropriate for a given measure • Added a new “multimodal transit LOS measure” • Responding to planning agency needs for multimodal LOS evalution • Can be used in conjunction with corresponding measures for the auto, pedestrian, and bicycle modes • Spreadsheet tool provided to help calculate the measure • New section on potential applications of QOS to real-world transit and transportation planning activities

  5. PerformancePoints of View

  6. Transit Performance Viewpoints • What aspects of transit performance might each of these groups be most interested in? • The transit agency • The community as a whole • The public works department • Transit passengers

  7. Examples of Measuring Different Stakeholder Viewpoints

  8. The Ultimate Transit Service As a passenger, what would your ideal transit service be like?

  9. The Ultimate Transit Service Since we can’t have the ultimate transit service, what trade-offs do we make?

  10. Transit Performance Viewpoints • Quality of service focuses on the passenger point of view • Other points of view are also valid and need to be considered • May have conflicting objectives (e.g., passenger comfort vs. agency resources) • Best-quality passenger service may not be feasible or desirable

  11. Quality ofService Factors

  12. What Matters to Customers? • Customer satisfaction surveys provide insights • TCRP Project B-11 (customer satisfaction surveying methods) • Florida transit agency on-board surveys • NCHRP Project 3-92 (multimodal urban street level of service) • Typical factors: • Frequency, wait time, service span • Reliability • Service close to home, destination • Crowding • Fares, driver friendliness, safety/security

  13. What Matters to Customers? • Factors can be divided into two main areas: • Service availability • Is transit an option? • Comfort and convenience • If it is an option, would you want to use it?

  14. Service Availability Spatial Availability(Origin) Spatial Availability(Destination) Temporal Availability Information Availability Capacity Availability Is transit an option for a particular trip? All five of these factors must be satisfied

  15. Service Availability Spatial Availability(Origin) Spatial Availability(Destination) Temporal Availability Information Availability Capacity Availability Is there a transit stop within walking distance? OR is demand responsive orprivate shuttle service available? OR is a car AND a convenientpark-and-ride available? OR is a bicycle AND bicycle storage available? OR is a bicycle available AND can it be brought onboard?

  16. Service Availability Spatial Availability(Origin) Spatial Availability(Destination) Temporal Availability Information Availability Capacity Availability Is there a transit stop within walking distance? OR is demand responsive orprivate shuttle service available? OR is a bicycle available AND can it be brought onboard? OR is a bike-sharing station with bicycles available?

  17. Service Availability Spatial Availability(Origin) Spatial Availability(Destination) Temporal Availability Information Availability Capacity Availability Is service offered at or near the times required?

  18. Service Availability Spatial Availability(Origin) Spatial Availability(Destination) Temporal Availability Information Availability Capacity Availability Are the schedule and routing known? OR is telephone, text, or Internet information offered, the service available when customers use it, and the information accurately provided?

  19. Service Availability Spatial Availability(Origin) Spatial Availability(Destination) Temporal Availability Information Availability Capacity Availability • Is space available to board the transit vehicle when it arrives? • When applicable: • Is space available in the park-and ride lot? • Is there an open spot on the bicycle rack OR is secure bicycle parking available at the stop? • Is there an available wheelchair position inside the vehicle?

  20. Typical Comfort and Convenience Factors • In-vehicle crowding • Can I get a seat, will I have to stand & for how long, how crowded is it? • Reliability • Can I expect to get to my destination at the scheduled time, or do I need to allow extra time? • Travel time • How long will my door-to-door trip take? How long would the same trip take using other modes? Will I have to transfer, and how easy is it? • Pedestrian and bicycle environment • Can I get to and from transit stops safely and directly? • Cost • How much will my trip cost? How easy is it to pay my fare? How much do would other travel options cost? • Safety and security • Amenities, appearance, maintenance, driver friendliness

  21. Quality ofService Framework

  22. Developing the QOS Framework • User outreach efforts during the development of the 3rd Edition found two main user groups for the QOS framework • Transit agencies • Like being able to evaluate many different aspects of QOS • Don’t like level of service (LOS) letters A-F: look too much like grades • Planning agencies • Comfortable with the LOS concept, apply it to other modes • Prefer a single LOS measure that can be compared to other modes • Both groups agreed that the 2nd Edition framework was measuring the right QOS factors • 3rd Edition QOS methods designed to meet the needs of both groups

  23. QOS Framework Changes • The 3rd Edition retains the basic QOS framework for transit agencies • Three aspects of availability, three aspects of comfort & convenience • Specific performance measure used for a given aspect may vary depending on scale of analysis (stop/route/system), vehicle type, or service type • Service level tables have been retained • LOS numbers and letters have been removed • Number of service levels allowed to vary from 6 as appropriate • Comments on the operator point-of-view for a given service level have been added to the existing comments on the passenger point-of-view • Designed to support service standards development and aid in interpreting evaluations of existing and future conditions

  24. LOS Approach: 1st and 2nd Editions TSA = transit supportive area (≥3 households/gross acre or ≥4 jobs/gross acre) • Service coverage example

  25. QOS Approach: 3rd Edition

  26. Multimodal Transit LOS Measure • The 3rd Edition adds a “multimodal transit LOS measure” for planning agencies • Measure developed by the NCHRP 3-92 project and subsequently incorporated into the Highway Capacity Manual 2010 • Provides A-F letters indicating the level of service • Incorporates most of the same factors in the QOS framework, but provides a single LOS measure • Access to transit: pedestrian environment • Waiting for transit: frequency, reliability, shelter/bench presence • On-board experience: passenger loads, transit speed • Index values and associated LOS letters can be directly compared to those from companion measures for the auto, bicycle, and pedestrian modes • Can be used to evaluate trade-offs in traveler satisfaction when allocating street right-of-way between modes • Spreadsheet included on the CD-ROM to help perform the calculations

  27. Quality ofService Measures

  28. Frequency • Transit service can only be used at discrete times • If service is only offered hourly, there is a very small window of time during the hour when a transit trip can be started immediately • More-frequent service provides more opportunities for immediate travel • Transit service more closely resembles competing modes (auto, bicycle, pedestrian) in terms of departure time convenience • Frequency is attractive to passengers • Ridership increases as frequency increases, although a diminishing returns principle applies • Frequency is a key driver of operating costs • Improvements to speed and reliability can allow better frequency at the same cost • When transfers are involved, frequency is only as good as the weakest link in the trip

  29. Frequency QOS • Seven levels • ≤5 minutes • >5 to 10 minutes • 11 to 15 minutes • 16 to 30 minutes • 31 to 59 minutes • 60 minutes • >60 minutes • QOS table listing the passenger and operator perspectives fills most of 2 pages, so only an example is shown here

  30. Service Span • Service span determines the potential markets that transit serves • Starting and ending times of activities • Work • School • Medical appointments • Shopping • Longer service spans serve a greater number of potential passengers • Non-traditional work hours • Night classes • Friday & Saturday night activities • Longer service spans than needed to serve a particular market give passengers flexibility • Ability to stay late • Insurance against being stranded

  31. Service Span QOS • Based on number of hours when service offered at least hourly • Six levels • >18 hours • 15 to 18 hours • 12 to 14 hours • 7 to 11 hours • 4 to 6 hours • <4 hours

  32. Service Coverage • Mode used to access transit depends on distance to travel and facilities provided along the way and at the transit stop • Walking is the most common access mode for urban transit service • 50-80% of persons walk ¼ mile or less to a local bus stop • 50% of persons walk ½ mile or less to rail and BRT service • Terrain, street connectivity, street-crossing difficulty, demography are factors • Bicycling can extend a stop’s market area • A person can cover 4 times the distance in the same time,compared to walking • Autos used in lower-density areas to access commuter/express bus and rail transit service when park-and-ride facilities are provided • Market area depends on area topography and access road network • Typical: 50% of demand comes from within 2.5 miles of lot, 35% of demand comes from upstream up to 10 miles away from lot

  33. Transit-supportive Densities • Ridership increases with density • More people (potential customers) located within a given area • Greater propensity for a given person to use transit • TCQSM provides guidance on densities capable of supporting particular service and modes • Values dependent on how much one subsidizes transit service • TCQSM values assume 33% farebox recovery (2010 US average was 27%)

  34. Service Coverage QOS • Five levels • >90% of population served • >90% of transit-supportive area served • 75 to 90% of transit-supportive area served • 50 to 74% of transit-supportive area served • <50% of transit-supportive area served • Transit-supportive area defined as an area capable of supporting hourly weekday transit service • At least 3 households per gross acre or 4 jobs per gross acre • Assumes 33% farebox recovery • QOS planned for depends very much on transit agency’s policy emphasis: coverage vs. cost-efficiency or frequency • QOS table shown on a previous slide

  35. Passenger Loads • Passengers perceive travel in crowded conditions as being more onerous than travel in less-crowded conditions, even when they have a seat • Value of time begins to increase when 80% of seats are occupied • Standing passengers’ perceived value of time considerably higher than seated passengers’ • Cost-effectiveness improves as passenger loads increase • Passenger throughput generally improves as passenger loads increase • Passenger boarding & alighting times increase as the number of standing passengers on-board increases

  36. Passenger Load QOS:Vehicles Designed for Most Passengers Seated • Nearly all buses, all commuter rail, all ferry, some other rail vehicles with narrow aisles and transverse seating • Six levels • Up to 50% seated load • Up to 80% seated load • Up to 100% seated load • Up to 125% seated load • Up to 150% seated load • >150% seated load

  37. Passenger Load QOS:Vehicles Designed for Most Passengers Standing • Special-purpose buses, most light and heavy rail • Six levels • >1.0 m2(10.8 ft2) per passenger • 0.5 to 1.0 m2 per passenger • 0.4 to 0.49 m2 per passenger • 0.3 to 0.39 m2 per passenger • 0.2 to 0.29 m2 per passenger • <0.2 m2(2.2 ft2) per passenger

  38. Reliability • The more unreliable the service, the more extra time passengers have to allow for their trip • Arriving at stops earlier than necessary • Taking an earlier trip than necessary • The more unreliable the service, the more recovery time that agencies need to insert into the schedule to compensate • Time could be better used in service (operating the route more frequently, operating a longer route) • Reliability issues depend in part on the scheduled headway • Short headways: bus bunching and train stopping/starting • Long headways: on-time performance, early departures

  39. Reliability QOS:Headway-based Service • Applicable to service that operates at 10-min headways or better,or to service without fixed departure times • Based on headway variability (standard deviation of headways divided by the scheduled headway) • Described in terms of the probability that a passenger arriving at a stop will experience a vehicle more than ½ headway off the scheduled headway • Six service levels

  40. Reliability QOS:Schedule-based Service • Applicable to service that operates to a fixed schedule • Based on on-time performance • Defined as a departure no more than 1 minute early and up to 5 minutes late • Five service levels • 95-100% • 90-94% • 80-89% • 70-79% • <70%

  41. Travel Time • Travel time is an important consideration in mode choice • Travel time impacts operating costs: the slower the route, the more vehicles that are required to be in service to provide a given headway

  42. Travel Time QOS Based on the ratio of in-vehicle transit time to in-vehicle auto time Six service levels

  43. Multimodal Transit LOS • Measure draws from research into ridership response to QOS changes and passenger values of time • Three main elements: • Frequency (average % increase in ridership as frequency improves) • Travel time (average % increase in ridership as travel time decreases) • Pedestrian environment (adjusts LOS up or down based on particularly good or bad pedestrian access to a stop) • Travel times are based on perceived travel times, expressed as a travel time rate (minutes per mile) • Bus stop amenities (value of time of shelter, bench) • Reliability (excess wait time) • Passenger load (perceived travel time rate) • Travel speed (actual travel time rate)

  44. Multimodal Transit LOS • Transit wait-ride score represents ridership for the route being evaluated, relative to a route with hourly headways and a baseline speed (typically 15 mph, 10 mph in major city downtown areas) • Score of 2.0 indicates a route would be expected to attract twice the ridership of the same route operating hourly with a 15 mph average speed • Transit LOS score incorporates the wait-ride score and the pedestrian LOS score and adjusts the result to use the same scale as the other modal LOS scores:

  45. Demand Responsive QOS • There is a corresponding QOS framework and measures for demand responsive transit • Covered in the DRT presentation

  46. Applications

  47. Potential Applications • Comprehensive planning • Long-range transportation planning • Statewide transportation planning • Service standards development • Comprehensive operational analysis • Transit development plans • Service planning • Corridor planning

  48. Comprehensive Planning • Multimodal comprehensive plans provide goals, policies, and objectives for the transit service provided, or desired to be provided, within a city or county • Service goals may be aspirational (city/county is not the service provider) • Service goals may become the basis for service standards (city/county is the service provider) • QOS measures relating to availability can be used in setting objectives • For example, minimum span of service for trunk and local routes • Information in QOS chapters can be used to demonstrate the impact of different land use densities, street connectivity, and sidewalk provision policies on transit access • Impact on ridership • Impact on number of households/persons with transit access • Impact on transit operating costs (e.g., number of route miles required to meet a service coverage goal)

  49. Long-range Transportation Planning • LRTPs identify city- or region-wide transportation needs over a longer period of time (e.g., 20 years) • If plan preparer is not the service provider, LRTPs often focus on the actions that can be taken to support transit (e.g., sidewalk improvements) • If plan preparer is the service provider, the transit element may be more specific and contain many of the elements of a transit development plan • A common application of the TCQSM 1st and 2nd Editions was to evaluate existing transit service quality • Much more valuable to also use it to evaluate service quality provided by various future alternatives, to aid decision-making • Possible types of analysis: • Activity center analysis (origin–destination trips) • Corridor analysis (transit streets, priority/frequent bus network) • Service coverage analysis (areawide, corridor)

  50. Statewide Transportation Planning • QOS measures derivable from National Transit Database data can be used to track trends in fixed-route transit provision across the state • Statewide, or broken out into population ranges • Example measures • Average system peak-period headway • Average system speed (revenue miles/revenue hours) • System service span • Measures require no special data collection
