Collins Bus Corp. d.b.a. World Trans Download PDF Report
Collins Bus Corp. d.b.a. World Trans submitted a model World Trans T24, gasoline-powered 18 seat (including the driver) 24-foot bus, for a partial STURAA test in the 7 yr. /200,000 mile category. The odometer reading at the time of delivery was 17 miles. Testing started on August 18, 2016 and was completed on September 28, 2016. The Check-In section of the report provides a description of the bus and specifies its major components.
The interior of the bus is configured with seating for 18 passengers including the driver, plus 1 wheelchair position. Note: this test bus is not designed to accommodate standing passengers, therefore seated load weight and gross vehicle weight will be the same value. At 150 lbs per person and 600 lbs per wheelchair position, this load results in a measured gross vehicle weight of 11,080 lbs. This weight exceeds the GVWR by 720 lbs. The ballast for 5 seated passengers was eliminated to avoid exceeding the rear GAWR (7,275 lbs) and the GVWR (10,360 lbs). Gross load is 150 lb. x 13 = 1,950 lbs. + 600 lbs. (1 wheelchair position) = 2,550 lbs. At full capacity within the GAWR, the measured gross vehicle weight is 10,340 lbs.
Effective January 1, 2010 the Federal Transit Administration determined that the total number of simulated passengers used for loading all test vehicles will be based on the full complement of seats and free-floor space available for standing passengers (150 lbs per passenger). The passenger loading used for dynamic testing will not be reduced in order to comply with Gross Axle Weight Ratings (GAWR’s) or the Gross Vehicle Weight Ratings (GVWR’s) declared by the manufacturer. Cases where the loading exceeds the GAWR and/or the GVWR will be noted accordingly. During the testing program, all test vehicles transported or operated over public roadways will be loaded to comply with the GAWR and GVWR specified by the manufacturer.
The performance of the bus is illustrated by a speed vs. time plot. Acceleration and gradeability test data are provided in Section 4, Performance. The average time to obtain 50 mph was 12.96 seconds.
A Fuel Economy Test was run on simulated central business district, arterial, and commuter courses. The results were 8.90 mpg, 8.78 mpg, and 15.36 mpg respectively; with an overall average of 10.07 mpg.
A series of Interior and Exterior Noise Tests was performed. These data are listed in Section 7.1 and 7.2 respectively.
The Emissions Test was performed. These results are available in Section 8 of this report.
