* Canada - Nova Bus: All-Electric Engine Cooling System
The Saint-Eustache,QC,USA -Mass Transit Mag -Feb 2011: -- A proprietary, integrated engineering electric engine cooling system improves the buses’ performance through reductions in maintenance costs, fuel consumption and polluting emissions... The system’s 13 variable-speed brushless fans are designed to last the life of the bus. Improved fuel efficiency affords up to 15 percent fuel economy from the lower overall power draw from the engine. Reduced maintenance costs are seen due to the elimination of the oil cooler and manifold. The system is positioned for the cleanest and coolest air intake... The all-electric engine cooling system is designed for serviceability and integrated in the Volvo multiplex system for easy diagnostics... (Image from novabus)
* USA - Thermo King Corp., a business of Ingersoll Rand – Alternator-Powered All-Electric HVAC
Minneapolis,Minnesota,USA -Mass Transit Mag -Feb 2011: -- While all-electric heating, ventilation and air conditioning for hybrid buses and trolley buses is a well-established technology, Thermo King offers a unique innovative solution that supplies high voltage power to the electric HVAC unit using an alternator driven by the bus engine. The alternator output is conditioned and stabilized before being used to power the electric compressors and fan motors regardless of engine speed... The alternator-powered all-electric HVAC system provides full capacity at engine idle, constant capacity throughout the speed range of the engine, lower maintenance costs, improved reliability, fuel savings and a control system that optimizes energy management and conservation...
* Ohio / USA - Greater Cleveland Regional Transit Authority – TransitStat
Cleveland,OH,USA -Mass Transit Mag -Feb 2011: -- TransitStat requires GCRTA’s management team to use data and information systems to define, measure, analyze, improve and control (DMAIC) operations... Stat programs are structured, continuous management processes, which entail the frequent gathering, reviewing and analyzing of day-to-day government performance. GCRTA holds weekly meetings led by OMB and an executive team to review performance, understand trends and make necessary adjustments to ensure that immediate and long-term goals are met... TransitStat affects the entire organization’s culture by signaling that performance and data-driven management is important... Over the past several years, GCRTA’s business strategy has focused on three goals: A) Maintain financial health, B) Improve customer service, and C) Enhance the image of GCRTA. In order to affect these goals, GCRTA must embrace a performance culture that manages by data. TransitStat enhances GCRTA’s ability to deliver performance needed to reach and exceed its goals...
* DC / USA - Capital Metro – Mirror Awareness Guide
Washington,DC,USA -Mass Transit Mag -Feb 2011: -- One of Capital Metro’s most common types of collisions was mirror-to-mirror. Surprisingly, more collisions occurred from vehicles overtaking buses rather than from oncoming traffic. To counter this problem, the agency developed its Mirror Awareness Guide (MAG) devices and affixed them to the street-side rear section of its buses. The MAG device is the width of a bus mirror and set to the center height of the street-side exterior mirror... The premise is simple: when an overtaking vehicle approaches the bus and begins to pass, the driver should notice the protruding MAG device, which focuses their attention on the bus, causing them to pass with a wider safety cushion... If they fail to notice the device and travel too close to the bus, their mirror will hit the device producing a loud noise without harming their mirror or the flexible MAG. This should encourage them to move away from the bus before striking its mirror...
* Connecticut / USA - CTTransit – Hydrogen Garage Modifications
CT,USA -Mass Transit Mag -Feb 2011: -- Initially, bus companies testing hydrogen-fueled buses spent millions of dollars building small separate garages or bays for these specially fueled vehicles. These facilities were very expensive as they were designed to contain an explosion should one occur. CTTransit felt this was the wrong strategy and hired a consultant with extensive experience working with hydrogen with sophisticated computer modeling tools... Hydrogen is the lightest element in the universe, and if released, it disperses quickly. It is only flammable or explosive if concentrated. CTTransit was able to prove to the state facility engineer and fire marshals a better way to handle a hydrogen leak was not to contain it, concentrating it, but dispersing it immediately... The approved final solution was groundbreaking and inexpensive. CTTransit placed hydrogen leak detectors in its bus and bus bay and connected both to the facility backup electrical power supply should grid power fail. It locked out/tagged out the bus’ hydrogen fuel system before bringing it into the garage and ran it solely on electric power... Plastic covers were placed over bus bay light fixtures to prevent hydrogen from entering them and eliminating the lights as a possible spark source. Ventilation ducts were lowered from the ceiling so a constant low flow of air would be directed on the bus at all times...
* Colorado / USA - Proterra: EcoRide
Golden, CO ,USA -Mass Transit Mag -Feb 2011: -- Traditionally, the barriers to employing battery-powered buses in large-scale applications were the range and charging needs of batteries. Additionally, the weight of traditional buses has made it difficult to feasibly incorporate a battery with sufficient power and energy storage capacity into coach designs... Proterra Inc. is unique in that it designs and manufactures an electric bus’ complete system, including its own TerraVolt energy storage system which includes batteries, battery management system and integration system, FastFill rooftop rapid charging system, ProDrive drive system using a UQM PowerPhase 150 motor with three-speed gearbox, and a Continental VDO master control system with custom programming... The Proterra EcoRide BE 35 is different than most battery drive vehicles where range is dictated by the number of batteries. The Ecoliner can operate 24 hours a day, seven days a week on routes outfitted with fast-charge stations... The key to this project is the utilization of the fast-charge battery. According to laboratory data, this battery retains its energy reserve and charging profile from 8,000 to 25,000 charge-discharge cycles and can be quick-charged from a 10 percent to a 95 percent charge in 10 minutes or less while the bus is at a layover... The EcoRide BE 35 offers zero emissions, potential for 90 percent reduction in fuel costs, significant noise reduction, lower maintenance costs and 90 percent regenerative braking energy recapture.
* BC / Canada - NextBus' real-time passenger information systems
Burnaby,British Columbia,CAN -Mass Transit Mag -Feb 2011: -- Used by more than 80 transit properties, including 30 colleges and universities, NextBus’ real-time passenger information systems provide services for city and county transit systems, resort shuttles, hospital and corporate campus shuttles, airport shuttles, and college and university transit systems. The largest transit properties in North America use NextBus, including Toronto (TTC), Boston (MBTA), San Francisco (SFMTA), Los Angeles (LACMTA) and Washington, D.C., (WMATA)... NextBus helps transit properties provide exceptional service to their customers. Riders will always know when their bus will arrive. Transit managers will always know where their buses are and if they are operating properly. Truly a win-win situation for everyone involved...Labels: techno buses
