Education Summary
According to the education data on Gloucester County, there are a total of 171 schools in the county, including 82 public elementary schools, 39 private elementary schools, 16 public high schools, 30 private high schools, 2 colleges and universities and 2 business/vocational schools. According to the US Census bureau, 77,861 are enrolled in the school system in Gloucester County.[2]
Transportation Summary
In Gloucester County, 93% of people use private transportation. Over 18% of the residents work outside of the state. Interstate 295 is the only interstate in the county and passes through the Northwest portion of the county, as does the New Jersey Turnpike[3]. There are sever state routes which pass through the county, such as Route 41, 42, 45, 47, 55, 77, 324 and others. There are no connections to NJ Transit train systems, but there is a bus route that is not very well developed.
PRT Network
We can see that the majority of the population of Gloucester lives in the larger townships and boroughs, such as Monroe, Washington, Deptford, Franklin, West Deptford and Glassboro. These were the municipalities that we had the most PRT stations in. Although the original goal was to have 90% coverage in the county such that the citizens would be able to have a PRT station within a quarter mile radius, in the smaller municipalities where there wasn’t as much population, this was not feasible. We managed to end up with a coverage of 81.14% service in the county.
For our PRT network we had grids on the east and west sides of the county because the population was essentially split that way. There were many more residents on the two sides than in the center of the county, and this can be seen through the placement of the PRT stations. We placed stations where there was an indication from the site that there’d be a profit, and in a few (rare) cases, we placed stations where the numbers were really close to the cutoff threshold for profitability (1000).
Gloucester County Final PRT Network
Gloucester County Northern Tip PRT Network
There is a grid network set up here and also in the Northeast. We did so because the grid setup is the shortest way for users of the network to get to where they need to go.
Northeast PRT Network
Year Built
For the Gloucester County PRT network, we decided to shorten the building time to 6 years instead of 20 because we felt that we would be able to realize more immediate profits if we finished building sooner. The following is a table indicating how many stations, interchanges, shape points will be built and guideway miles will be laid in the 6 year time period for this project.
PRT Summary
Below are the summary statistics for Gloucester County for the PRT network.
This is a graph of the trip ends served per station arranged in decreasing order.
From the above chart we can see that with a fare of $3 we can expect to make a profit of $122 million dollars. In order to build the network, however, we would have to pay a fixed cost of $4,438 million dollars or 4.4 billion dollars. This is because there is a large number of stations (434) and interchanges (210) and there is a total guideway length of 472 miles. These stations and interchanges allow for the PRT network to cover 81.14% of the county.
The following is a graph of how annual P&L would look with different fare costs. It can be seen that once the cost of a ride exceeds $2.50 it because profitable to build the PRT network in the county. We recommend charging a bit more initially because due to the way people view increases in price, they will be very averse to price increases (which will be necessary later due to inflation and other costs increasing).
Notes for future classes:
Now that we’ve finished with the networks for the counties that we worked on, we have a few notes we’d like to make about the networks. First off, we’d like to point out that the data really needs to be scrubbed down. There are many duplicate placemarks in the csv files that we were given and also placemarks that had completely unreasonable numbers for employees and visitors, causing there to be stations with huge ridership numbers. What we did to remedy this was that we went through and deleted duplicate placemarks and also rescaled the number of recreation trips by a constant factor so that we’d end up with a total number of trips that seemed reasonable. Something else that we noticed was that there’s a problem with the PRT page in that the numbers will only update if you wriggle the mouse around a bit, so that caused us to place some stations in areas that were not particularly profitable, but the way that the site works makes it really difficult to find and delete these stations.
