2 2 Outline The Right Time for Mobility at Clemson (Motivation and Research Questions) Methodologies Overview of Results Venues for Dissemination Concurrent Research

3 Motivation and Research Questions

4 4 Motivation at Clemson Trustee mandate: no new surface parking lots Increasing demand for parking  Ten years ago: ~30% of freshmen brought cars to campus  Now: ~80% of freshmen bring private vehicles 2004 hiring of a new parking director 2006 study to create a Parking and Transportation Management Plan

5 5 Mobility Matters Access and mobility help define the intuitive feel of a campus Safe, easy, and convenient transportation systems can help attract students, faculty and staff

6 6 University Priorities Efficient transportation can enhance the experience of visitors and returning alumni Environmentally conscious transportation planning can help preserve natural beauty & meet regional goals

7 7 Unique Environments University campuses are vibrant, distinct communities made up of people from different backgrounds, incomes, lifestyles and attitudes. Diverse demographic and socioeconomic characteristics require a diverse set of mobility options. University campus land use can provide an environment where multi-modal transportation systems can work

8 8 The Clemson University Transportation Challenge Goal: A pedestrian friendly campus Highest and best use of campus land  Surface parking lot conversion (multi-million dollar garages?)  Increased research space and activity A balanced transportation systems approach is needed  Multi-modal focus Need to understand how the campus currently moves  Travel demand surveying

9 9 Objectives  Discuss best practices identified from literature and case study investigation.  Examine Clemson campus transportation system challenges and opportunities  Conduct statistical and spatial analysis of travel patterns in the Clemson community.  Make recommendations for transportation systems and capacity allocations that will help to create a sustainable multi-modal campus transportation system How does Clemson move?

10 Methodology

11 11 Questions Under what circumstances do people move at Clemson? What are the populations of interest for developing a transportation system? What types of trips do we need to understand? What do we need to know about those trips?

12 12 Triple-Survey Structure Three distinct surveys aimed at different aspects of campus transportation issues  Internet Survey November 21 – December 6, 2005 Large sample Stated and revealed preference questions on general daily travel patterns  Travel Diary September-October 2006 coinciding with Clemson University parking inventory and demand study Small sample Revealed behavior with substantial detail  Football Intercept Survey 2005 season (5 out of 6 home games) Large sample Major events with  Special traveling populations  Unique origin-destination needs  Concentrated time requirements

13 13 Human Subjects Research Stringent requirements for review of research procedures, instruments, risks, and ethics  Nazi medical experiments  Addictive drug research Special consideration of minors (freshmen?) What kind of risks could the campus surveys pose?

14 14 Internet Survey 1,614 valid responses Tree structure (Each survey was unique according to how the person answered it)  Classification as student (on or off campus)/faculty/staff  Primary mode used  Other modal preferences Widespread distribution, e- mailed to all Clemson faculty, staff, and students

18 18 Travel Diary More focused on trip characteristics than previous two surveys Entirely revealed behavior of trips throughout the day over the course of week  Origin-destination data  Time of day  Location-specific reporting Paper format, easy to carry along for the day Recruitment  401 potential participants allowing personal contact  As of October 12 th, diaries distributed 49 diaries returned What about statistical significance?

19 19 Diaries… not state of the practice Activity diaries Vehicle instrumentation GPS packs Expense? Equipment reliability? Modal bias? Privacy?

20 20 Football Survey 946 respondents for the season  ±3.2% confidence interval  95% confidence level  Student undercount Paper surveys directed at anyone entering the stadium, aiming to catch all modes, all gates Collected throughout games, but primarily before kick-off, at half- time and post-game

26 26 Do You Have Reasonable Access to Places Within Clemson University?

28 28 What Type of Parking Pricing Would You Prefer On Campus (Off-Campus Students)

29 29 “I Need A Car…” (On Campus Students) 1=Least Agreement and 5=Most Agreement

30 30 Gas Prices Results of the Internet Survey show that gas prices have a bigger effect on the travel habits of Clemson students and staff compared to faculty Driving less and combining trips were the two most cited effects of increased gas prices for students, faculty and staff

31 31 Reasons People Do Not Walk

32 32 Walk Commute Times to Campus

33 33 Who is Riding Transit? On-Campus Students Off-Campus Students Faculty & Staff 40%53%5%

34 34 Why Do We Not Ride Transit? “Bus routes do not serve my needs” “Bus schedule does not serve my need” “Service frequencies do not fit my needs” “I need the flexibility to come and go during the day” “It takes more time to get to campus when I ride transit”

35 35 Bike Facilities 915 people regularly bike to and around campus 52% of all respondents requested more bike lanes, 20% are willing to pay higher student fees for them 48% of all respondents requested covered bike racks, 19% willing to pay higher student fees for them December 6, 2005November 17, 2005

39 Alternative Transportation Options

40 40 How Often Would You Ride Commuter Rail Between Clemson and Greenville? 31% of the Clemson community would use commuter rail every week. 60% of the Clemson community would use commuter rail every month.

42 42 Golf Carts??!!!! Mobility: Access across campus improves with easy access to low-speed transportation. Congestion: More golf carts than autos can park in the same space Convenience: With smaller vehicles, more vehicles can park in existing lots closer to buildings. Environment: Address regional air quality issues and non-attainment with emphasis on electric or propane golf carts. Cost:  Students can use a $2000 golf cart (or a $200 bicycle on the same infrastructure) instead of a $20,000 private vehicle.  The University assumes little cost for operating this mode.  The University maximizes existing infrastructure, reducing need for costly garages. Character:  Clemson further establishes its name for automotive technology through practical use of alternative fuel vehicles.  A golf-cart campus will help distinguish Clemson as a unique top-twenty university. Golf carts have a place in this community, but will people use them?

43 43 "If Clemson provides appropriate parking and right of way, golf carts and similar small personal vehicles can serve as a viable transportation option for the community." On-campus Students Faculty Staff Off-campus Students 33.2% of the campus community sees golf carts as a likely viable transportation option.
