  • Abstract:
    The  limited  funding  available  for  roadway  capacity  expansion  and  the  growing  funding  gap,  in  conjunction  with  the  increasing  ; congestion, creates a critical need for innovative lane use management options for Indiana. Various cost‐effective lane use management  ; strategies have been implemented in the US and worldwide to address these challenges. However, all the strategies have their own  ; costs, operational characteristics, and additional requirements for field deployment. Hence there is a need for systematic simulation‐ ; based methodology to perform a comprehensive study to identify congested corridors and the specific set of lane use management  ; strategies that are effective in Indiana.   ;   ; A systematic simulation‐based methodology is proposed for evaluating lane use management strategies. A 10‐mile stretch of the I‐65  ; corridor south of downtown Indianapolis was selected as the study corridor using traffic analysis. The demand volumes for the study  ; area were determined using subarea analysis. Its performance was evaluated using a microsimulation‐based analysis in the context of  ; alleviating congestion for three strategies: reversible lanes, high occupancy vehicle (HOV) lanes and ramp metering. Furthermore, an  ; economic evaluation of these strategies was performed to determine the financial feasibility of their implementation.   ;   ; Results from this analysis indicated that reversible lanes and the ramp metering strategies improved traffic conditions on the freeway in  ; the major flow direction. Implementation of the HOV lane strategy resulted in improved traffic flow conditions on the HOV lanes but  ; aggravated congestion on the general purpose (GP) lanes. The HOV lane strategy was found to be economically infeasible due to low  ; HOV volume on these lanes. The reversible lane and ramp metering strategies were found to be economically feasible with positive net  ; present values (NPV), with the NPV for the reversible lane strategy being the highest.
