Restructuring Transportation for Tight Budgets

Computerized routing: North Carolina case studies
North Carolina has developed an extensive computer-assisted school bus routing and scheduling system that has helped school districts plan more efficient routes and reduce costs. The Transportation Information Management System (TIMS) compiles student data, street maps, attendance boundary maps and hazard reports to create safe and efficient bus routes.

Under the state's school transportation budget constraints, districts are using TIMS to test the viability of new strategies for cutting costs while serving the same population of students.

At CMS, Carol Stamper reported to the superintendent on changes being made to school bus operations for the 2009-10 school year in order to meet required local and state budget restrictions and to improve efficiency.

Carol Stamper of Charlotte-Mecklenburg (N.C.) Schools instituted changes in transportation to help deal with the district’s estimated $3 to 4 million budget shortfall.

Among the changes made were bus stop consolidations, which led to the elimination of 11,000 (nearly one third)of the stops routed in the previous year. Despite the drop in bus stops, the average walking distance to stops for students was only 0.12 miles.

In addition, routes for two high schools that had been served by separate buses were combined, bell schedules were adjusted at two schools, grandfathered transportation was eliminated and through a transportation audit, ineligible students were removed from bus assignments.

Collectively, the changes are projected to reduce ridership by 1,000 out of 112,000 students transported daily, reduce the number of routes by 100, and save 11,000 miles daily. "We are always assessing our operation for efficiencies and dollar savings," Stamper says. The operational changes this year are likely to save a great deal in transportation dollars for the district. "However, at this point, the district has not given any indication of potential budget impacts for 2010-11," she explains.

CMS has also equipped its entire fleet - including school buses, activity buses, and service and fuel trucks- with GPS systems over the past 18 months. "Last year, we realized over $1 million in savings by reducing overtime by monitoring and managing driving time," Stamper says. "We also reduced excessive idling time by more than 50 percent. We have not quantified this in dollars just yet, but we know it reduced fuel costs somewhat and, more importantly, improved air quality."

The Cabarrus County Schools transportation office used TIMS software during the summer to create a new transportation plan, which was implemented for the 2009-10 school year. Analysis of the district's school bus runs showed that a three-tiered, staggered bell time schedule and pairing of some runs would allow a reduction of the bus fleet by nearly 25 percent while serving the same geographic area and number of students.

Most buses now make three morning and three afternoon runs instead of two, increasing daily miles by 30 miles per bus. However, 53 buses were taken off the road, and student ride time has gone down across the board. On top of that, an additional 1,545 students are assigned to buses this year over last year.

"The only real challenge has been the routes and schedules are much tighter," Transportation Director George Douglas says. "Everyone has to relax and let things settle down after the first few days. The TIMS information, if well maintained, will prove to be accurate."

Cost benefits of privatizing
Lakota Local School District in Liberty Township, Ohio, privatized transportation with Petermann in 2004. Under tough economic conditions, the transportation program began looking at changes to make to routing for the 2009-10 year and achieved a savings of $1.5 million per year by shifting a bell time, significantly reducing the number of buses needed.

High school students were also required to register for transportation beginning this school year, and preschool and K-1 students who were previously transported on separate buses although their programs are housed in the same building were combined onto the same buses. "The result of those three changes, plus being a little tighter on our routing efforts, was that we were able to reduce from 221 routes last year to 198 routes this year. And we are transporting the same number of students," Petermann Area Manager Mike Miller says.

Bus routes also no longer go into cul-de-sacs or make other types of "sweetheart stops," promoting efficiency.

Privatizing led to another cost-cutting benefit for the school district - the elimination of health care and liability costs for the 280 transportation staff members, not having to spend capital on bus purchases, and significant savings on worker's compensation. "The school district was able to self-fund its worker's compensation for our employees. We couldn't do that when we had transportation as a district responsibility," says Chris Passarge, director of business operations for the district.

Route changes require district teamwork
Sioux Falls (S.D.) School District was facing a budget cut this year of about $1.4 million. Jim Shafer is a manager at School Bus Inc., the company that provides transportation services for the district. "We have a good working relationship, so we sat down and explored different ways of doing things.I think they were looking to cut $250,000 from our budget, and we actually exceeded that by the time we got routed up this year."

Bell time adjustments and route consolidation were key moves for meeting those budget requirements. "I see it being permanent for quite a few years. When the budget gets tight, it's something they'll do, and when it loosens up, they'll move back. It's a way to reduce routes and save the district money."

First, Shafer combined half-full buses serving nearby elementary schools. "The logistics of it are not the best. Some students have to ride a little bit longer because the two schools have the same bell time. Then somebody's got to stay late to watch the students until we can get there from the other school [at the end of the day]," he explains.

To eliminate some middle school routes, Shafer had the school move its bell time back by 15 minutes to allow buses to take longer routes and load more students. "Sioux Falls is still growing, and we've been opening a new elementary about every two to three years," Shafer says. "If the numbers get big enough, it may just force adding another bus."

Lastly, Shafer combined routes for special programs in the district, cutting bus runs to the special-ed preschool and family immersion center by half. "We were covering the same territory serving both schools. It was going to take 16 routes to do the two schools separately, but we were able to reduce eight routes by tying the programs together."
