NYSERDA/ NYSDOT Final Presentation Understanding Commuter Patterns & Behavior; An Analysis to Recommend Policies Aimed at Reducing Vehicle Use Agreements 11108, C012668, C-08-30, & PIN R.021.27.881 September 16 th 2010
Availability of Alternative Transportation • Main finding on accessibility and availability of alternative transportation. – Unless on a CDTA line, it is difficult for a UAlbany commuter to take bus transportation. – While there are bus lines that do make stops at UAlbany, their schedule is incompatible with the majority of the worker’s and student’s schedule. – Most buses make one stop on campus between 7 and 7:30 am and pick up around 4 pm. – There is an abundance of information and resources available as to bus routes and park and rides via the CDTC. However, it is difficult to get commuters to take advantage of their services. – There are concerns with safety in biking and walking to campus.
Availability of Alternative Transportation • Current conditions: Parking The following steps have been fees are very low taken by the University in the – ($20 – 100) last year: • The campus population has • Participating in IPool2. access to CDTA lines and the • Participating in the vanpool UAlbany shuttle for free . program • Hired Zipride to coordinate a ride share program. • Offering Universal Access to CDTA bus lines • Contracted with Connect by Hertz to provide a car share program • Graduate planning studio Master Bike Plan
Availability of Alternative Transportation • Overview of GIS analysis was performed on parking permit data – Able to identify clusters of commuting population to encourage and identify carpool and vanpool opportunities. – Able to identify commuting commonalities between UAlbany and Harriman campus employees. – About half of employee commuters living in Albany, Rensselaer and Schenectady counties are being served by a CDTA bus line within a 1/4 mile of their home. – Less than 20% from Saratoga county are being served by a CDTA line

Summary of GIS analysis • Albany County has the largest commuter base with 56.52% of the permits distributed listing an Albany County address. • The highest density of students is within two Albany communities (12203, 12208) and Clifton Park (12065). • Albany zip codes of 12203, 12205 and 12208 have the highest density of staff commuters. • Albany (12203) and Delmar (12504) have the highest density of faculty. • Clifton Park (12065) and two Albany communities (12205, 12203) have the highest concentration of Harriman commuters. • Approximately 45 to 50% of UAlbany commuters live within a quarter mile of a CDTA bus stop
On-Time Performance Analysis Using GPS to Evaluate the Effectiveness and Reliability of Mass Transit Serving the University at Albany
Background The current body of literature on Transportation Demand Management (TDM) and evaluating on-time performance of transit systems was reviewed. • Use of GPS allows for time and spatial analysis • Schedule adherence of departures used as performance metric • Use multiple timing points as posted in transit schedule to conduct ride check • For each time point along route determine if bus is early, on-time, or late • On-time performance is the difference between scheduled and actual departure time of bus from time point • On-time percentage=OT departures/Total departures*100
Methodology Definition of Departures: • Early - Actual departure occurred before scheduled time On-time Performance LOS • On-time - Actual departure occurred 0- 5 minutes after scheduled time On-Time Level of Service • Late - Actual departure occurred more Percentage (LOS) than 5 minutes after scheduled time 95.0 – 100.0% A Defining Level of Service(LOS): 90.0 – 94.9% B • The LOS definitions are derived from a 85.0 – 89.9% C manual produced by the Florida Department of Transportation that details how to 80.0 – 84.9% D conduct a comprehensive operational analysis of transit 75.0 – 79.9% E • Based on the on-time percentage it is possible to grade the LOS provided by the <75.0% F transit agency
Unit of Analysis • The transit routes under Map of CDTA Route 12 investigation in this study include CDTA routes 11 and 12 and the UAlbany Shuttle routes that serve Western Ave and Madison Ave • The map shown on the right illustrates CDTA route 12 • The blue line indicates the path the bus traveled and the red dots are timing points
Deployment • The deployment of the study occurred for three weeks during the fall semester • A total of nineteen student workers were trained to ride the bus routes being studied and collect GPS data • The GPS data has been post-processed and converted to a file format compatible with Microsoft Excel for analysis • An analysis template has been developed in excel that converts the GPS time to seconds past midnight, reports the on- time percentage of departures and grades the level of service provided by the transit agency
On time percentage and reliability • Mean provides on Statistical Analysis of Routes time percentage of On t i me percentages bus route Mean Stand. Dev. • Standard deviation • CDTA Route 11 71.4% 8.90 indicates reliability • CDTA Route 12 65.8% 17.20 of route • Low s.d. indicates a • UAlbany- Madison 64.8% 9.90 consistent level of service • UAlbany- Western 60.2% 7.90
On time performance • Routes: CDTA 11 and 12 • Both routes experienced a large percentage of early departures (leaving prior to scheduled departure)
On time performance • UAlbany shuttle: Western and Madison routes • Both routes experienced a large percentage of early departures (leaving prior to schedule departure)
