In 2000, a survey of Maryland motor carriers indicated that electronic data interchange and Internet technologies were valued more by carriers with large fleets (25 or more vehicles) that conduct business with state agencies.
FINDINGS
Respondents were asked to rate the potential value of Electronic Data Interchange (EDI) and Internet for conducting business with Maryland State Agencies. On a scale of one to three the…
