VI-3 Based on the 1995 APTA data, and similar to transit buses, NHTSA assumes that 92.6 percent of paratransit buses sold are lift eq~ipped.~However, for purposes of cost analysis and to ~CCOUIit for future paratransit bus lift installations, the agency is assuming 100 percent are lift equipped. The 1996 distribution of demand response vehicles in-use estimated by FTA was; MPVs (50%), automobiles (27.78%) and buses (22.22%).’ WTSA assumes that demand response vehicle sales are proportional to the in-use distribution. Applying these proportions to the above annu 11 estimate of 1,290-1,720 paratransit vehicles yields; 645-860 MPVs, 358-478 automobiles, and 287-382 buses sold annually. For purposes of analysis, NHTSA assumes only 50% of the vans/MPVs are lift-equipped with GVWR >4,540 kg (10,000 lbs.) and that 100 percent of the paratransit buses are lift-equipped for a total of 610 - 812 paratransit units per year [e.g., S(32 J to 430 MPVs + 1.0(287 to 382) buses] that would be affected by the subject rule annually.6 Paratransit automobiles are excluded fiom the analysis since they would be equipped with roo ; trunk, or rear bumper mounted lifts that do not lift the occupant. School Buses - The agency does not how many school buses are lift-equipped. Type I1 school buses [also known as Type A (-40,000lbs. GVWR) and Type B (>10,000 lbs.)] are designate11 for use by disabled and special education students. Over the last 6 years, school bus sales havl; 4 1997 Transit Fact Book, APTA, see page 82, page 85 - Table 50 and page 89 - Table 54. FTA is the Federal Transit Administration, U.S. Department of Transportation. 6 The proportion of MPVs >4,540 kg mass (10,000 lbs.) GVWR which are lift-equipped vs those that aw ramp-equipped is unknown. NHTSA assumes a 50/50 split.
VI-4 averaged 35,000 units per year, of which 16 percent are estimated to be small, Type-A school buses and 84 percent are estimated to be large Type B, C and D school buses. Based on 1993 School Bus Fleet magazine data, it is estimated that between 18 to 20 percent of the Type-A school buses are lift-equipped or 1,008 - 1,120 [(.16)(.18 to .20)(35,000)] units per year. Fort ie large, Type-B, C and D buses, it is estimated from the same School Bus Fleet magazine report that 5 to7.8 percent are lift-equipped or 1,470-2,293 [(.84)(.05 to .078)(35,000)] units per year ’ Therefore, combining the Type A, B, C and D lift-equipped school bus estimates together yielc Is 2,478-3,413 total lift-equipped units per year. The Access Board’s guidelines apply to school buses implicitly due to the Rehabilitation Act of 1973, which mirrors the ADA. NHTSA is not mandating that school buses be equipped with lifts. But if they are voluntarily equipped with lifts they must meet FMVSS No. 404 and install an FMVSS No. 403 compliant lift. Over-the-Road Buses (OTRBs) The ADA accessibility requirements do apply to OTRBs or what are commonly called intersta1.e buses or motor coaches. A recent departmental final rule requires that 50 percent of the OTREI; fleet be accessible by 2006 and 100 percent by 2012.’ It is expected that accessibility would b8: accomplished by a level change device - primarily WC lifts. NHTSA’s FMVSS Nos. 403/404 standards would apply to OTRBs. According to the OST Regulatory Analysis (PRA) September 28, 1998,3,000 units are sold annually of which 400 are exported and 400 are converted to 7 School Bus Fleet, DecembedJanuary 1993 issue, Bobit Research Department, Bobit Publications, 25 1 !
