• Abstract:
  Suburban arterial roadways must serve two conflicting road functions: regional mobility and access to the abutting land. The potential for conflicts between traffic passing through and traffic accessing road from the neighboring areas could raise safety concerns. Selecting an adequate cross-section is among important decisions that road designers and traffic engineers consider when mitigating the mentioned conflict. The following three alternative treatments offer different access control levels: undivided cross-section with no median, two-way left-turn lane instead of a typical median, and non-traversable median. The frequency of access points and the selected median treatment option should be commensurate.
