The InRoads products have evolved from products developed by Intergraph in the 1980s. The first Intergraph civil product was called the Engineering Site Package (ESP) and ran on a DEC VAX from graphic terminals. ESP combined coordinate geometry with terrain modeling and profile/cross section extraction in a single product.
Following this, a Transportation Design System Steering Committee was formed in December, 1986 to set the direction for a road design product. The original members were:
This design system was called "TDP", which stood for Transportation Design Package was released.
The product was renamed InRoads when it became available on the InterPro 32 running the CLIX operating system (variant of UNIX). What follows is a brief history of the product:
