This study specifies and empirically tests an econometric model to examine the relationship between usage of information and communication technologies (ICT) by firms and measures of accessibility to transportation supplies, built environment, and business activity. The results show that better accessibility to local and regional transportation facilities is associated with a higher propensity of ICT usage by firms. Additionally, the likelihood of high business-related ICT usage is positively correlated with built environment attributes including employment density. Moreover, firms in sectors such as communication, information, real estate, and finance have a higher propensity of using ICT. These results provide a better understanding of the determinants of ICT usage by firms which can influence business-related travel and thereby, impact traffic congestion levels within an area. The findings can be used to develop firm-level policies regarding ICT usage based on new investments in transportation supplies or changes in the surrounding built environment.
