The purpose of the (I-15 RLCS) is to open and close the reversible lanes for morning and evening peak
traffic hours and any special events defined by operators of the system. The software developed from
this specification will replace the current aging and non-expandable RLCS Application. In addition, new
controller devices, as well as field device interface cards will be provided by the successful bidder, and
the software will interface with these new field hardware components via interfaces to driver software.
