INTEGRATING ASSESSMENT OF THE ECONOMIC BENEFITS OF TRANSPORTATION IMPROVEMENTS IN PROJECT-LEVEL ALTERNATIVES ANALYSIS Meiwu An, Pikes Peak Area Council of Governments Maureen Paz de Araujo, HDR Tim Roberts, City of Colorado Springs

PROJECT OVERVIEW 1. Fillmore Street: Interstate 25 to Centennial Blvd 2. Fillmore/Chestnut/Interstate 25 Intersection

Fillmore Street experiences significant congestion and queuing during peak periods Traffic flows will increase in the future Morning and evening peak hour queuing extends far up the “Hill”

Pavement condition and inadequate shoulders are unsafe for pedestrians and bicyclists rough pavement surface and lack of sidewalk is daunting to pedestrians and bicyclists Steep grades, narrow shoulders and …

I-25 EA Approved Interchange Concept Single Point Urban Interchange (SPUI) Today’s Signals

What Are the Project Benefits?  Improves Traffic Operations  Helps boost economic development opportunities along the corridor  Constructs missing infrastructure  Enhances transit operations and facilities  Minor reduction in Vehicle Miles Traveled

ALTERNATIVES

Alternative 3

Benefit Estimate  Congestion reduction: vehicle hour traveled(VHT) savings  Comparison between no-action and alternative scenario  Regional VHT difference  Traffic operational improvement  Conversion to dollar benefits  Categorize VHT savings by truck/car, on-clock/other trip  Input to TREDIS (Transportation Economic Development Impact Software)

Benefit Cost Analysis  Project benefits  Travel time savings for road users  Vehicle operation cost savings for road users  Environment benefits for public (air quality)  Reduced travel time variability  Project cost  Design  Right-of-way acquisition  Construction costs  Maintenance costs

Benefit Cost Analysis  Travel time saving for road users  Value of time by trip purpose  Vehicle occupancy  Car and Truck variables  Accident cost savings (not included)  Reduce potential for accidents  Reduce cost to users

Proposed Action  Easily be integrated with CDOT’s Preferred Alternative  Signalized intersection with the realigned Chestnut Street requires raising of Fillmore Street  Coordinate with CDOT to acquire necessary Right-of- Way (2 Gas Stations)  Feedback from Parker Street residents has been in support of the cul-de-sac  Minimum of 3 Parker Street homes as part of acquisition

Conclusion  Public/social investment  TDM and traffic operation analysis  Delay savings benefit  The results consistent with expectations  Technical information is one measure
