Morgantown Personal Rapid Transit (WVU PRT) is a personal rapid transit (PRT) system in Morgantown, West Virginia, United States. The system connects the three Morgantown campuses of West Virginia University (WVU) and the city's downtown area.
Developed from the Alden staRRcar and built by a consortium led by Boeing Vertol, the driverless system was a government-funded experiment in PRT systems. Upon its opening in 1975 with three stations, it had a fitful start, being three years behind schedule and costing 3–4 times more than estimated. It was expanded in 1978 to its current five stations, two maintenance depots, and over 70 vehicles. Like all PRT systems, stations are built on sidings, which allows vehicles to bypass stations and permits express trips between any two station pairs.
While the system achieved reliability upwards of 98% for most of its life, its reliability declined in the 2000s – dipping to 90% by 2015 – and it gained a reputation for unreliability. In response, a renewal project was approved in 2012, which has so far replaced the vehicle control and propulsion systems, replaced parts of the power supply, and repaired other infrastructure. A new vehicle control system is due to be commissioned by 2018, and the vehicle fleet will also be replaced.
Morgantown is a small city with about 30,000 permanent residents, with close to 140,000 in the metropolitan area. WVU adds 28,000 seasonal residents from August through May.:3 As WVU expanded in the 1960s, geographic constraints – the city is situated in a mountain valley along the Monongahela River – forced WVU to build a second campus 2 mi (3.2 km) away in Evansdale. Free busing was offered to move students between the campuses, but all the roads led through the city center, creating gridlock more typical of a megacity.
In the late 1960s, Samy Elias, who led WVU's industrial engineering department, learned of experiments with PRT in the U.S. after the HUD reports were published. A minor PRT craze was being set off by a combination of federal funding and estimates that showed a PRT system would be far less expensive to build and install than any other form of mass transit. Elias felt a PRT would be a perfect solution to the traffic problems in the city.
Gathering support from WVU, the City of Morgantown, and West Virginia's congressional delegation, Elias arranged a $50,000 development grant from the Urban Mass Transportation Administration (UMTA) for a comparative study of three PRT systems: the Monocab, Dashaveyor, and the Alden staRRcar. The Alden staRRcar was found to be the most suitable system for Morgantown.
Political pressure by Senator Robert Byrd led Secretary John A. Volpe of the then-new United States Department of Transportation to propose that Morgantown be used as an experimental site for PRT development. President Richard Nixon had expressed strong support of the PRT concept, and Volpe was trying to arrange to have an experimental system well underway before the next presidential election, in November 1972.
Examining the proposals, the UMTA decided that Alden was far too small to be able to handle the job, and arranged for the Jet Propulsion Laboratory (JPL) to take over as systems management role, signing a contract with them in December 1970. Boeing Vertol was selected to build the vehicles, Bendix Corporation supplied the control systems, and F.R. Harris Engineering would design and build the guideway, stations, and other facilities.
The original estimates for the system were $15–20 million. But having set a deadline based on political considerations, rather than technical, the system had to be rushed through to completion as soon as possible. JPL, used to running large engineering projects with a stepped approach, had to abandon the study stage and move the project directly to engineering tests.
Numerous problems cropped up as a test system was set up at Boeing's plants, notably the requirement to heat the tracks to melt the snow that collected in the U-shaped guideways, resulting in costly changes to the design. By the time the original deadline passed, the system was already massively over-budget and nowhere near ready for buildout. Instead of a feather in Nixon's cap, the system became a political chess piece and was derided in the press as a white elephant.:3
There were large cost overruns during the development of the system, and it was not until 1974 that the system had matured technically. Construction of the first guideway in Morgantown started that year, and was completed the next. The Phase I system began operations in 1975, with a final cost of $62 million, four times the estimate. It consisted of 5.2 mi (8.4 km) of guideway, 45 vehicles, 3 stations, and a maintenance/control facility.:3
Service was interrupted during the 1978–1979 school year for a system expansion, dubbed Phase II, during which WVU provided bus service between the campuses. The system was extended from the "Engineering" station towards new stations at "Towers" (dormitories) and the WVU Medical Center/Mountaineer Field. Phase II cost $64 million, bringing the total for the entire system to $130 million.:3 Upon its completion, the system had 71 vehicles, 8.65 mi (13.92 km) of guideway, and 5 stations. One existing station had also been expanded, and a second maintenance facility was added.
Although the system's construction ran far over budget, it still proved to be what its designers had claimed: a reliable system of automated transit that was inexpensive to operate. It has offered on-time service rates far better than the bus services it replaced, and eliminated the gridlock that had locked up the city center. Moreover, no injuries were reported for the first 42 years of operation, until the first reported accident in November 2016. From July 2005 to June 2006, about 2.25 million rides were taken on the PRT. As of November 2007, the PRT transports about 16,000 riders per day. The record for most riders in a day is 31,280, set on 21 August 2006. In 2003, about 60% of costs were covered by the 50-cent fares.
Morgantown's economy boomed in the 2000s and the city was noted for having the lowest municipal unemployment rate in the U.S. Mayor Ronald Justice said, "We're a small town with big traffic issues, and the PRT could be the reason we're able to continue our growth."
There are two proposals to extend the line from both ends: one would extend southward to the new commercial and shopping area being developed as part of a riverfront revitalization project, while a longer extension is being considered to the northwest to connect a new research park. If both extensions are completed, at an estimated $30–40 million a mile, the system would almost double in length.
On November 30, 2016, the system had its first reported accident when two PRT cars were involved in a crash between the Beechurst and Walnut stations. There were six passengers on board and two were treated for minor injuries. Service to Walnut station was suspended for several days while the incident was investigated.
The system has 73 vehicles that resemble small buses. They are 15 ft 6 in (4.72 m) long, 8 ft 9 in (2.67 m) high and 6 ft 8 in (2.03 m) wide. Weighing 8,760 lb (3,970 kg), they are powered by a 70 hp (52 kW) motor that allows them to reach 30 mph (48 km/h).:9
The vehicles have automatic doors on both sides that open to the platform, and are accessible for people with mobility disabilities. The vehicles are designed for 20 passengers, with four seats arranged in a "U" on each end and four stanchions in the center of the vehicle for twelve standees. A yearly event called the PRT Cram takes place in which student organizations try to pack as many individuals as possible inside a modified PRT vehicle. The record of 97 was set in 2000.
The cars are powered by three-phase 575-volt alternating current rectified to drive a 70 horsepower (52 kW) direct current motor. Electric pickups are fixed on both sides of each car, which connect to electrified rails on one, or both, sides of the guideway. The wheels of the vehicles steer slightly toward whichever side is powered to ensure that they stay in firm electrical contact with the rails. Each car has four-wheel steering to help negotiate the tight turns in the PRT trackways, especially around stations.
The system connects the university's campuses via five stations (Walnut, Beechurst, Engineering, Towers, Medical) along a 3.6 mi (5.8 km) route. All stations are on sidings, which allows vehicles to bypass stations.
The track consists of concrete pathways with magnetic induction loops that provide car location data. The system's concrete pathways have embedded pipes that circulate a glycol solution, which is heated at stations to help melt snow and ice prevalent in Morgantown's snowy winter climate.:9
Most of the system (65%) is built on elevated bridges and viaducts, while the remainder is at or below ground level. The viaduct spans are approximately 30 ft (9.1 m) long, and there are two styles of viaduct, with those constructed in Phase I being noticeably heavier-duty than those built in Phase II.:9
Modes of operation
The system is fully automated and can operate in three modes: "demand", "schedule", and "circulation".:6
In demand mode, which is used during off-peak hours, the system reacts dynamically to rider requests. After pressing the button to call a car, a timer starts. If the timer reaches a predetermined limit, typically 5 minutes, a vehicle is activated to service the request even if no other passengers have requested the same destination. Also, if the number of passengers waiting to travel to the same destination exceeds a predetermined limit, usually 15, a vehicle is immediately activated.:6 In this mode the system operates as a true PRT.
During peak hours, the system switches to schedule mode, which operates the cars on fixed routes of known demand. This lowers the waiting time for a car traveling to a given destination and is more efficient than demand mode. During low-demand periods, the system switches to circulation mode, operating a small number of vehicles that stop at every station, like a bus service. This reduces the number of vehicles traveling on the network.:6
In the 2006 fiscal year, the system broke down 259 times for a total of 65 hours and 42 minutes, out of a total of 3,640 hours and 15 minutes scheduled running time, which equates to about 98% availability. Of those 259 breakdowns, 159 were caused by vehicle-related problems. In 2007, the system received funding to improve efficiency by reducing this vehicle downtime.
Since the system's completion in 1975, technology for PRTs has advanced considerably, but the control equipment for the Morgantown system changed very little. The control room is said to resemble a NASA mission control room from the 1970s, though the underlying electronics are more modern.
Morgantown PRT operates chiefly as transportation for WVU's students and, as such, runs primarily during class days. During the fall and spring semesters, it operates during 6:30 am–10:15 pm weekdays and 9:30 am–5:00 pm on Saturdays. It is normally closed on Sundays. During the summer semester, it operates 6:30 am–6:15 pm weekdays and 9:30 am–5:00 pm on Saturdays, and is closed on Sundays. When major WVU events – notably football and men's basketball games – are scheduled to end outside of normal operating hours, the system will run for at least an hour after the end of the event. The system is closed on holidays and during semester breaks.
When it opened, the PRT was controlled by DEC PDP-11 computers installed in 1971. Due to difficulty in procuring replacement parts, these older computers were replaced in 1997-1998 with Intel Pentium computers.
A 2010 study recommended renewal of the system given declining reliability caused by its age and the lack of access to replacement parts for key components, such as the vehicles and the control system. The report considered replacement of the PRT with buses but concluded they would be unsatisfactory given the extra traffic congestion and poor travel times that would result. By 2015 reliability had fallen to 90%.
In 2012, the university Board of Governors approved $15 million as part of renewal and modernization project. The total cost is projected to be $100–$130 million. The three phase plan is to replace the control and propulsion systems in the current vehicles, installation of a new automatic train control system, upgrade the power supply, repairs to the infrastructure and finally replacement of all the vehicles.
Part of the phase 1 work to upgrade the vehicles' control and propulsion system was completed by early 2014 and resulted in improved operations.
On April 29, 2014, Thales Group was selected by WVU to install its SelTrac Communications-based train control (CBTC) system, as well as new systems for fare collection and passenger information. Upgrades occurred during the summer breaks in 2015 and 2017 while the system is normally closed. Replacement of the train control system will continue during the fall 2017 and spring 2018 semesters in preparation for full-scale testing and commissioning during the summer of 2018.
For the vehicle replacement in phase 2, which has not commenced as of September 2017[update], the university has said it will look for vehicles that weigh 2,500–3,000 lb (1,100–1,400 kg),, about one-third the 8,760 lb (3,970 kg) for the current fleet.
The $52.6 million phase II renovation of the PRT is still being completed. Over the winter break of the 2017-2018 academic year, 11 cars were converted to a new software. The updated cars have not been used during typical business hours as they are not compatible to the current system. In addition to receiving new software, Phase II also includes replacing electric boards and sensors on the guide ways and signs.
