, 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 stations. While the system achieved reliability upwards of 98% for most of its life, its reliability declined in the 2000sdipping to 90% by 2015and 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 was commissioned in 2018, and the vehicle fleet is also being replaced. The system has operated reliably, and currently is in full operational service as of Nov 2021, transporting students and staff daily.

Construction

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 guideways 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 A white elephant is a possession that its owner cannot dispose of, and whose cost, particularly that of maintenance, is out of proportion to its usefulness. In modern usage, it is a metaphor used to describe an object, construction project, sch ...
. 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 of guideway, 45 vehicles, 3 stations, and a maintenance/control facility. 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 A dormitory (originated from the Latin word ''dormitorium'', often abbreviated to dorm) is a building primarily providing sleeping and residential quarters for large numbers of people such as boarding school, high school, college or university s ...
) and the WVU Medical Center/ Mountaineer Field. Phase II cost $64 million, bringing the total for the entire system to $130 million. Upon its completion, the system had 71 vehicles, 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 August 21, 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.


Accidents

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. On February 10, 2020, two PRT passengers, and WVU students, were taken to Ruby Memorial Hospital for injuries due to a boulder that dislodged from the nearby hillside striking a PRT car. One student on the PRT was seriously injured and suffered multiple pelvic fractures. A driver, on nearby Mon Boulevard, was also taken to the hospital after their vehicle collided with another boulder that was part of the same disturbance.


Description


Guideway

The guideway is a dedicated roadway for rubber-tired vehicles that allows close separation between vehicles. It is a network that connects all stations and the maintenance facility. The guideway is used mostly by the PRT vehicles except in an emergency where maintenance workers can drive a car up to tow a non-functioning PRT vehicle off the guideway. The guideway is a concrete structure with about half of its length elevated. It has three-phase 575 VAC, 60-Hz propulsion power rails on the sidewall that are equipped with electric heating for cold weather operations. Below the power rails is a steering rail that allows the guidewheel of PRT vehicles to be pressed against to steer along the guideway. Communication

Vehicles

The system has 73 vehicles that resemble small buses. They are long, high and wide. Weighing , they are powered by a motor that allows them to reach . The larger vehicle size of the Morgantown Personal Rapid Transit has led some to consider it a "group rapid transit" (GRT) system, instead of a true personal rapid transit system. 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

. 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 guideways, especially around stations.


Route layout

The system connects the university's campuses via five stations (Walnut, Beechurst, Engineering, Towers, Medical) along a route. All stations are on sidings, which allows vehicles to bypass stations. It takes 11.5 minutes to ride the entire length of the system from the Walnut Station to the Medical Station. The guideway consists of concrete pathways with magnetic induction loops that provide car location data. The system's concrete pathways have embedded pipes that circulate a

solution, which is heated at stations to help melt snow and ice prevalent in Morgantown's snowy winter climate. 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 long, and there are two styles of viaduct, with those constructed in Phase I being noticeably heavier-duty than those built in Phase II.


Modes of operation

The system is fully automated and can operate in three modes: "demand", "schedule", and "circulation". *Demand: When used during peak hours, the system reacts dynamically to rider requests, comparable to utilizing an elevator. At the fare gate, after the rider pays the fare, they will press the button associated with a particular destination to call a car. This will start a timer within the system. 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. User will look at the electronic signboard above the boarding gate to determine which car to board. Once the car arrived, the doors remain open for 20 seconds for boarding, before the vehicle departs to its destination, avoiding any intermediate stations. In this mode the system operates as a true PRT. *Schedule: System switch to this mode during periods with well-known travel-demand patterns, and 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. *Circulation: System switches to this mode during off-peak hours, operating a small number of vehicles that stop at every station, like a

. This reduces the number of vehicles traveling on the network, but increase travel time to destination.


Performance

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. , the system's cost per trip is $2.01, the third least expensive (after New York and Boston) for any fixed guideway system in the

Operation hours

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 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 is closed (as of 2021).

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 upgraded to the 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.
