PRECURSOR SYSTEMS ANALYSES OF AUTOMATED HIGHWAY SYSTEMS. FINAL REPORT. ACTIVITY AREA I: IMPACT OF AHS ON SURROUNDING NON-AHS ROADWAYS

This study considers the influence which automated highway system (AHS) traffic would have on the conventional, non-automated freeway and street system as it approaches and departs from the automated roadway. The higher speeds and capacities possible with an AHS facility will attract traffic into the AHS lane from both the general purpose freeway lanes and the parallel arterials. The increased AHS traffic will have both positive and negative impacts on the surrounding street system. The analysis includes the modeling and evaluation of the operations of a freeway corridor with and without an AHS lane. Operations with and without an AHS lane on the surrounding roadways are then evaluated using traffic operations measures of effectiveness. The surrounding roadways include the general purpose freeway lanes, freeway ramps, parallel arterials, and cross streets. Additional modeling analyzes the impact of the AHS traffic on the cross streets. The Highway Capacity Software (HCS) program is used to evaluate the level-of-service on alternative configurations of the cross streets and parallel arterials. The physical requirements of the AHS lane and ramps are analyzed to determine the impact on the surrounding streets. The modeling results are also used as input to the Activity P analysis. Qualitative as well as quantitative impacts are addressed. AHS is reviewed from the perspective of an urban planner.
