The software enjoyed considerable success in the US during the 1990s and is now the dominant software for transportation planning in the United States.īecause Caliper had created an easy-to-use mapping and GIS interface as part of TransCAD, they decided to release Maptitude, a powerful mapping tool for business users who are not GIS professionals but who still need to utilize location intelligence. TransCAD was first released as a MS-DOS-based transportation GIS package in 1985. In developing TransCAD, Caliper sought to embrace and incorporate various research advances in the field of GIS, including an early version of an algorithm devised by Evans, S P. The beginning of this journey started with Howard Slavin and his collaborators developing TransCAD. Moreover, Caliper’s software, TransCAD, is the first and only Geographic Information System (GIS) designed specifically for use by transportation professionals to store, display, manage, and analyze transportation data. Recognized as a leading consulting and R&D provider offering professional services in quantitative management consulting, transportation, and decision support systems development, Caliper software products are supported with extensive technical services in GIS applications and training, database development and software customization. Legacy meets Technology: Founded in 1983 and headquartered in Newton, MA, Caliper Corporation, is a tech-giant in the development of geographic information systems (GIS) and transportation software.
