A roadway system (1) comprising a primary lane (2, 3, 4, 5, 6, 8) suitable for unidirectional, vehicular use, adjacent to a plurality of passing zone segments (10). The primary lane (2) provides a surface for single file traffic flow. Each passing zone segment (10) provides a surface for single file, vehicular traffic flow in the same unidirectional direction. Each passing zone segment provides an entrance (7), a passing lane (9) and an exit (11). Each passing zone segment (10) is sequentially disposed at a repetitive interval adjacent the primary lane (2). A traffic island or median (12) is provided to separate the primary lane (4) and the passing lane (9). Center line (50) separates lanes of opposing traffic directions (4, 8).
