S. DEPARTMENT OF TRANSPORTATION CENTERS PROGRAM1. Abstract. A survey of United States school bus operators and manufacturers was conducted to defined the larger sizes of school buses in regular use. A mid- 6. 0 passenger type- C bus (SB- C) and a mid- 8. D bus (SB- D) were selected as design vehicles.

Both the dimensions (length, width, etc.) and the trace of turning path swept through 9. During field tests, these school buses made turns somewhat sharper than those of the AASHTO design single unit or bus vehicles. Simulation methods such as computer- generated templates replicate the field turns fairly well in mid- turn, but do not well replicate the spiral at the end of a turn. The long rear overhang of these school bus design vehicles allows the outer rear corner of the vehicle to swing outside the wheel path at the beginning of a turn, and therefore be a design consideration in some situations.

Recommended SB- C and SB- D turning path templates were developed and presented. Key Words DESIGN VEHICLE, SCHOOL BUS, TURNING RADIUS1. Distribution Statement NO RESTRICTIONS.

E., and Micheal D. Howard. CHAPTER 1. INTRODUCTIONThe physical and operating characteristics of vehicles that will be using a roadway are important controls affecting the geometric design of a new roadway. Characteristics of interest to roadway design engineers include a vehicle's dimensions, weight, turning radii, offtracking, acceleration, and braking. To properly design roadways or other facilities, the largest vehicle expected to use the facility with considerable frequency will be used as a design vehicle (AASHTO, 1.

No school buses are included among the fifteen design vehicles presented in both the 1. Green Book (AASHTO, 1.

Green Book (AASHTO, 1. These American Association of State Highway and Transportation Officials (AASHTO) publications do contain two design vehicles, the single unit truck (SU) and the single unit . The Green Book states . On most facilities serving truck traffic or large buses, however, the design vehicle either for semitrailer combinations or large buses should be considered in design.. A design vehicle designated BUS with a 2.

The objectives of this study were: 1. None of the Green Book turning templates for AASHTO design vehicles show the rear overhang path. However, a large rear overhang could cause the outside rear trace of the bus body to be a controlling design factor.

The turning path boundaries are determined by the outer trace of the outer front overhang and the path of the inner rear wheel. Geometric design requirements are more severe for trucks and buses than for passenger cars due to longer wheelbases and greater turning radii. The longer single unit trucks and buses require greater turning radii due to their greater offtracking. Offtracking is the phenomenon by which the vehicle's rear wheels do not follow the same path as the front wheels; this is very obvious during slow speed, sharp turns.

Little literature was found on the testing of the geometric design attributes of school buses. Testing tractor- trailer combinations has been a popular research topic in the past decade, and articles written about these tests provided ample literature about testing methods.

BUS DESIGN LITERATURESchool bus standards are presented in the 1. National Standards for School Transportation(CMSU), which states that the overall length of school buses shall not exceed 4. The first configuration is the .

A type C school bus has an engine located in front of the windshield and under a projecting nose. The entrance door is located behind the front wheels. The second configuration is the flat- nosed .

The engine of a type D school bus may be located at either the front (behind the windshield) or the rear. The entrance door is located ahead of the front wheels. Both types are designed to carry more than ten persons and have a gross vehicle weight rating (GVWR), which is the manufacturer specified loaded weight, of 4. Passenger capacity can be increased by adding more seats, without changing either the length or width of the bus. The AASHTO single unit truck (SU) or the single unit bus (BUS) is sometimes used as a surrogate design vehicle for school buses (see Table 1).

TURNING PATH METHODOLOGY REVIEWSources that have provided information about turning paths include several Transportation Research Record (TRR) articles, which mostly cover methodology. Three types of methods have been used to determine the turning path and offtracking of vehicles. The first type, field observations, involves observing actual vehicles performing turning maneuvers and determining the vehicle's path. The second method makes use of mathematical formulae, which have been developed to approximate existing vehicle turning data. The third type, model simulation, was developed to be more expedient than testing with actual vehicles.

Model simulations have been performed with scale models, hand- drafted models, modeling tools such as the Tractrix Integrator, computers, and templates. download Folklore Ps3 (Glennallen) here. A recent study published in the ITE Journal concerning reversing tractor- trailer combinations used many methods to determine turning paths (Schuster and Terry). According to one of the authors of the article, full- scale testing of the vehicles was performed and scale drawings of the test facilities and surrounding area were used to determine the vehicle's path. Chalk was used to mark some of the tractor- trailer's paths and the locations of these paths were determined by measuring to known objects in the surrounding area.

Additionally, some of the movements were video- taped and later used to determine the physical dimensions of the vehicles. Observational Methods. One observational method, full- scale testing, involves observing a vehicle under defined test conditions in a controlled testing environment, such as the Society of Automotive Engineers field testing procedure described in the following. Another type involves observing vehicle positions in actual on- the- road operations by means of ground- based and overhead cameras.

The earliest offtracking research used full- scale testing of actual vehicles. Early tests were run on test track curves with a known radius (Heald). More recently, the Society of Automotive Engineers (SAE) has developed a field testing procedure to determine a vehicle's turning radius (SAE). The method consists of the following steps.

Check steering geometry alignment and correct, if necessary. Check the front wheel cut angles to manufacturers' recommendations. Wheel stops should be set that the minimum interference is 2. In some cases, tire interference will be the limiting factor and in others, the steering gear travel will limit the maximum cut angle. Load the vehicle to the maximum recommended gross weight.
