The document discusses the implementation of a headway control system for buses in Santiago, Chile to address the problem of bus bunching. It presents an optimization model that minimizes passenger wait times by controlling bus holding times and speeds based on real-time location and demand data. Simulation results show reduced wait times and more even headways and bus loads. The authors developed software called Buzz Assist to retrieve real-time bus data and send control instructions to tablets on buses. A pilot test in two bus services saw a 40-50% reduction in fines for irregular headways. The technology was also integrated with an existing fleet management system.
Urban transport networks are gradually making the switch to electric vehicles, which raises the question of charging. Charging one bus is easy. But what about charging 20, or 50, or 200? The Cway bus fleet charging system has been designed to meet this need.

Acting as a technical analysis lead for the Metro Vancouver Mobility Pricing Independent Commission, WSP experts studied the use of congestion charging and mobility pricing for the Metro Vancouver Regional District.
An eight-month study ensued and resulted in a crucial set of data categorized by geography, time of day, and pricing level. The goals of the study remained: reducing congestion, generating additional revenue for the governing body, and promoting fairness.

Resumen:
In recent decades, the main focus in public transport operations has been increasing its speed. Increasing speed not only allows for faster trips, but also a higher frequency with the same fleet, thus reducing waiting times and crowdedness inside the vehicles. This interest in speed has ignored a second key dimension in level of service: reliability. In this article, we provide a full range of impacts of an unreliable public transport service. We demonstrate how regularising headway could improve level of service beyond the gains of simply increasing the operational speed. Regular headways positively affect comfort, reliability, travel and wait time, operational costs, and even some urban impacts of bus services. Thus, the focus for public transport agencies and operators should be redirected to reliability. This is fundamental for making public transport an attractive travel alternative and therefore must become a core goal for urban sustainability.
Gabriel Oliveira - BRT in Brazil: state of the practice as from the BRT Stand...BRTCoE
Presented by Gabriel Oliveira, Gabriel Oliveira, ITDP Brazil Public Transport Coordinator, on September 20th, 11:30 Brasilia Time Zone.
Complete title: BRT in Brazil: state of the practice as from the BRT Standard & challenges for operations and integration
Summary:
Between 2004 and 2014, the total extension of BRT systems almost quadrupled worldwide, rising from about 700 km to 2,600 km (ITDP, 2014). In an effort to monitor and guarantee an standard quality of service across systems, the Institute of Transport and Development Policy (ITDP) has consolidated, along with BRT planning experts and practitioners, a project and operations evaluation tool: the BRT Standard. The tool is divided in seven categories and 42 quantitative metrics that allow further comprehension of BRT state of the practice. It has been used to evaluate more than a hundred corridors in over 60 cities around the world.
In Brazil, where the concept has first been developed between the 70’s and 90’s, a second wave of BRT expansion in the last decade summed up more than 250 km built in nine cities and metropolitan regions, an increase of about 150%. In this presentation we aim to assess the state of the practice in sixteen operational Brazilian BRT corridors, drawing out the common challenges faced in their implementation and operations, the best practices identified and the main improvement points. The assessment is based in an exploratory and explanatory analysis of their BRT Standard scoring, where we highlight the case that stand out in each particular category or metric of the tool.
Scoring reveals good performance in basic BRT infrastructure elements (such as segregated bus lanes that are typically median aligned, off-board fare collection, level boarding and bus priority at intersections) and in service planning. Performance in categories such as station design, infrastructure sustainability and branding/information communications present greater variance depending on the corridor context.
However, the main challenges appear on the access and integration category, where system design and connection with the surrounding urban environment and active modes present flaws, and on operational issues, such as overcrowding and inadequate maintenance. This webinar will present the opportunity for participants to debate on these operational and integration challenges and how can they be overcome.
In a broader manner, this study also aspires to influence for more evidence-based policy and decision-making on urban transit investments, not only in the Brazilian context, but also in other contexts where BRT is steadily growing.

Juan Carlos Muñoz - Connected and automated buses. An opportunity to bring re...BRTCoE
Connected and automated trains have been successfully built for decades. And connected and automated cars are promising to become a reality in our streets in the next decade. What about buses? What are the benefits of having buses connected and automated too? This talk will analyse some of these benefits focusing on the prospect of avoiding bus bunching and the impact this may have in the level of service of bus users.

11. Bus bunching is a challenging problem
Increases average waiting times
Pushes transit agencies to increase the number of buses
Reduces transit comfort and reliability
Solution: Control headways
12. Schedule-based control
• Common in USA and Europe
• Low frequency services
• Not appropiate for Transantiago
High frequency
Congestion
Long services (60+ km) with more than 120 stops
Buses overtake each other
• Schedule adherance is extremely difficult
Requires a lot of effort by the people involved in operating the system
Not flexible: partially considers real-time information
12
13. ¿In Transantiago?
Fine system => Multas: ICF e ICR
Guarantee frequence and regularity compliance
Fines whenever heaways exceed a threshold
Have put into evidence the lack of solutions cost-
effective solutions available in the market
13
14. Proposed headway control model
• Rolling horizon mathematical programming optimization
model (Delgado et al., 2012)
• Minimize user waiting times subject to system constraints
• Seeks to regularize operation and address bus bunching
with real-time information
• Decision variable: holding times at bus stops, increase or
decrease bus speed
• Buses do not follow a schedule: supply is adjusted to
demand depending on real-time system conditions (traffic
and bus headways and capacities)
14
15. Simulation results
• Both in BRT corridors and mixed-traffic services the
following benefits have been observed:
Reduced waiting times and their variability
More regular headways: decreased regularity fines
More even bus loads: improved bus confort
Improved cycle time regularity making terminal
operations smoother
15
16. Simulation results: video
No control
With control
Circle: buses
Color: bus loads
(green: empty….red: at capacity)
16
17. Headway control software: Buzz Assist
• Develop software and implement solution in real bus
services
• Retrieve real-time bus location and run optimization
model with a frequency of one minute
• Control instructions are then sent to any Android
(commercial or industrial) tablets (with GPS and data
plan) installed in the buses
• Software is flexible enough to adapt to existing transit
system technology (GPS devices and consoles)
• Operates in headway and schedule based control
systems
17
18. Software: Input information
• Static transit system data:
• Bus services, operating programs, bus stop locations, etc: data in
General Transit Feed Specification (GTFS) format (used by Google
Transit)
• Real-time bus positions:
• GPS devices already installed in buses
• Tablet GPS
• Demand data:
• Passive smart card information: OD matrices and historical bus stop
arrival rates
• Segment speeds:
• Combination of real-time speeds with historical speeds
18
19. Synoptic & dashboard web tool
• Visualize buses and control instructions, modify system
parameters and download daily operating reports
19
26. Buzz Console
• Currently testing in real operating conditions different devices:
commercial tablet vs. industrial console
• Start pilot test in B22 and B14 services (February 2015)
• Obstacles: anti-theft and ruggedized support structures
• Lessons: offer an integrated service (both hardware + software)
and relevance of headway control in terminals
26
27. Integration to existing technological system
• We have successfully integrated our technology to an
existing fleet management system (with Subus Chile S.A)
