This paper investigates the relationship between modal accessibility and the home-work spatial configuration of two-commuter households in an urban area. The home-work spatial configuration is captured by: (a) total commuting distance of the two commuters (from home to work) and (b) the angle between the two work locations (as measured from the common home location). The household travel survey data of 2011 of the National Capital Region is used for the empirical investigation. The empirical investigation reveals that higher modal accessibility increases the angle and reduces the total commuting distance. This investigation also reveals that certain two-commuter households are not able to optimise their home location in terms of widening the angles and reducing total distances. A correlation between total commuting distance and angle between work locations is observed such that angle decreases as the distance between home location and the Central Business District (CBD) increases. We infer that two-commuter households located far from the CBD live in predominantly residential areas that lack employment centres. As such, land use policies should guide development in areas far from the CBD towards mixed land uses. These findings are useful for urban transportation and land use planning since the proportion of two-commuter households is increasing in many urban areas.
