Parking and Traffic Studies at SMF……

1. Parking and Traffic Studies at SMF…… How Can Airport Operators Reduce Vehicle Trips & Congestion ?? San Diego Airport Air Quality Symposium Jim Humphries - Sacramento Int’l Airport

2. SMF Has Unique Operational Constraints • CARB Imposed AQC Mitigation Requirements on SMF for Construction of New Runway in 1982 • Parking Capacity Originally Limited to only 4270 Spaces • CARB Objective Was to “Encourage” Rideshare and Mass Transit • Environmental Groups Want SMF to Fund Light Rail with Increased Airport Parking Fees $$$$$$$

3. Cars Planes GSE Regional Services • SMF Serves a Region of 25+ Sprawling Counties • ~ 150 Scheduled Flights per day • ~ 7.5 Million Passengers in 2000 • ~ 98% are O & D Passengers • ~ 20,000 Passengers per day • ~ 30,000 Vehicle Trips per day • Total SMF Emissions Roughly Equivalent to the Amount Generated by the Vehicles Attracted to a Single Large Shopping Mall ! SMF Combined Pollutants

4. SMF Customer Characteristics Most Air Passengers Unwilling to Pay High Fees for Taxis, Vans, or Parking Low Awareness of Public Transit Many Government Travelers (20-30%) LT Parkers Likely to be Frequent Users on 2-4 day Business Trips “Drop-offs” Likely to be Infrequent Users on 4+ day Pleasure Trips (more in summer) 30% of Travelers Carpool Taxi / Van Usage = 5-6% of Passengers, 1-2% of TotalTrips

11. Case Study Re-circulation

12. Successful SMF Landside Management Techniques • Dual Terminals- each with own Curb, Roadways, & Parking Shuttles • Additional Parking Capacity • Proper Pricing of Short-Term Parking • Consolidated Rental Car Facility with Single Shuttle Bus System • Improved Van & Taxi Services

13. Improved Van Services

14. Unsuccessful SMF Efforts • Limiting Parking Capacity • Consolidating Hotel Shuttles ? • “Pay-on-Foot” Parking • Taxi / Van Discount Coupons • Public Bus Service • “Major User” Rideshare Policies

15. Lessons Learned • Each Airport Situation is Unique • Customers Want Speed and Convenience • Customers May Out-maneuver Your “Social Engineering” Efforts • Public Transit May Not Significantly Reduce Trips & Emissions • Lack of Parking Increased SMF Trips • Biggest Trip & Congestion Reductions from Eliminating “Drop-offs"

16. Carefully Manage Parking Capacity Pricing Should be Perceived as a Value Understand Seasonal Variance in Customers & Their Access / Parking Habits Increase Public Outreach Activities Encourage Passengers to Plan Ground Transportation at Time of Flight Planning Provide Very Good Signage Recommendations
