2002 GBNRTC External Origin and Destination Survey
Executive Summary
Overview Purpose: The Greater Buffalo-Niagara Regional Transportation Council (GBNRTC) conducted a roadside driver-intercept survey during the fall of 2002. The purpose of the survey was to gather data on the travel characteristics of vehicles entering and exiting at a select number of highways along the perimeter (cordon line) of Erie and Niagara Counties. The data will be used to update regional travel demand models and to better comprehend the impacts external (non-resident) traffic has on the local transportation system. Types of Data Gathered: The survey was designed to gather the following information from all vehicles: • • • • • • • • • •
location where the trip began (origin) location where the trip ended (destination) purpose of trip type of vehicle number of occupants state where the vehicle was registered time of day vehicles entered/exited the region number of days per week drivers completed the trip whether or not the driver was a resident of Erie or Niagara County where vehicles passing through the region entered and exited Erie and Niagara counties
In addition to the information listed above, commercial truck drivers were asked to provide the information listed below: • • • •
gross weight of their vehicles how full their vehicle was at the time the survey was administered type of cargo carried the placard identification number for trucks transporting hazardous cargo.
Sampling Methodology The survey administration process involved stopping a random sequence of vehicles passing through each station in both directions and verbally interviewing the driver. The percentage of vehicles surveyed was based on the number of completed surveys required to achieve statistically valid results given the average daily traffic volumes on each highway that was included in the sample. The goal was to obtain data that had a precision of at least +/-5% at the 95% level of confidence for each station in both directions.

2002 GBNRTC External Origin and Destination Survey
Executive Summary
The actual number of completed surveys exceeded the goals that were established for all stations. Altogether, data was collected from more than 13,000 vehicles. The overall results have a precision of at least +/-1% at the 95% level of confidence. The precision of the data for individual stations is provided in the individual station summaries at the end of this report.
Site Selection and Advance Preparation Site Selection. During September 2002, the project management team from ETC Institute and GBNRTC staff field checked every site proposed for the survey. The decision on where to locate each survey station was site-specific and based on an evaluation on of the following factors: sight distance shoulder width speed limit number of adjacent driveways available parking the location of comfort service facilities. ETC Institute assumed responsibility for the administration of all traffic control tasks. ETC Institute drafted traffic control plans for NYSDOT. The traffic control plans were finalized by NYSDOT and accepted for approval as part of the Highway Permit application process. Pilot Test. ETC Institute conducted a pilot survey on November 11, 2002 in Amherst, New York. The pilot survey was conducted at a low volume road near the Hampton Inn in Amherst. The pilot test served as a “full dress rehearsal” to test every aspect of the survey so that the administration procedures could be constructively evaluated. All surveyors were required to pass ETC Institute’s certification examine. Of the 25 who attended the pretest, 22 passed the exam. Those that did not pass the examination were not allowed to participate in the actual administration of the survey. Public Awareness. GBNRTC issued a press release to local television, newspaper, and radio stations a few days before the survey was scheduled to begin. The purpose of the press release was to inform the public about the reason the external cordon survey was being conducted. The press release did not contain the actual locations where surveys were to be conducted. Although press coverage was limited, articles did appear in several local newspapers and a local radio station interviewed the GBNRTC’s Executive Director. The survey was conducted over a two-week period during November 2002. The survey locations are described below:

Station Description Each station consisted of a well-marked checkpoint, where the drivers of vehicles entering and exiting the study area were stopped and asked to provide travel information. Between 8 and 16 interviewers worked under the direction of a station manager to conduct the interviews at each station. Station managers reported to a senior researcher who supervised the overall operation. The survey was administered on Tuesday through Thursday, Nov 12-14, and Monday through Wednesday, November 18-20, 2002. In general, the survey stations were operated continuously from 7:30 a.m. until 4:45 p.m. The availability of daylight caused some stations to begin slightly later in the morning or end slightly earlier in the evening. Once surveying was underway, there were no closures due to rain or inclement weather. GBNRTC assisted ETC Institute in the arrangement of a uniformed officer and marked patrol car at every survey location. The presence of an Erie County or Niagara County sheriff deputy conveyed a sense of creditability to the project while contributing to the safety and security of each interview site.

2002 GBNRTC External Origin and Destination Survey
Executive Summary
Data Entry and Geocoding Data Entry. Dual data entry was completed for 100% of the surveys that were administered. Dual data entry involved having all completed surveys entered into two independent databases by different people. After the initial data entry was completed, the files from each database were merged and screened for records that did not match. Records that did not match were corrected in each of the databases. The files were then merged again, and records that still did not match were corrected again. This process was repeated until all records in each of the two databases matched. This process ensured that the database was nearly 100% accurate. Geocoding Process. All geocoding was performed in TransCAD 4.0 (build 133) using street address and zip code information. Survey addresses were first matched to the parcel map file provided by the GBNRTC. The remaining (unmatched) addresses were matched to the Caliper Streets 2000 file (a TIGER/Line derivative). TransCAD uses address standardization procedures. A number of standard data integrity checks and corrections were performed before actual geocoding was conducted. This included the identification of duplicate records and corrections to the spelling of street names and zip codes. The quality of the original survey database was very good. The contents of the original survey database were converted to MS Access for further processing before geocoding. The MS Access .mdb format was selected due to its widespread accessibility, facilitating data exchange. A number of standard data integrity checks and corrections were performed within the MS Access database before actual geocoding was conducted. This again included the identification of duplicate records and corrections to the spelling of street names and zip codes. Preprocessing activities included the following: 1. Establishing a unique numeric ID for each record. This unique ID remained with the record though any further processing and allowed the linking of the data even after partial processing, as long as the ID field was kept unaltered with each record. 2. Systematic review of availability and data types within address fields including street address, zip code, city, and county. For example, records with missing values in any one of these fields were corrected to the extent possible using other, supporting information within the database as well as through additional review by the data entry personnel. Any identified spelling errors or typographic errors were corrected at this point as well. Geocoding was performed using Caliper Corporation’s standard address matching/geo-location engine and verified using equivalent ESRI software tools, both set to double precision units. The current version of the engine provides some of the most sophisticated address matching functionality available. The accuracy of the geocoded records was also verified on a sample basis (spot checking) using Tele Atlas geocoding engine and street reference datasets.

Executive Summary
The Caliper U.S. Streets file has been standardized, or “cleaned up”, so that streets are named in a consistent way. For example, “Ave” is always used as the abbreviation for “Avenue,” and “2nd Ave” is used instead of “Second Avenue.” When features are located by address, Caliper’s software standardizes these addresses the same way and then attempts to match records in user data to features in the Streets file. The standardization rules are based on those used for creating TIGER/Line files. In some cases standard city names reflect names for unincorporated areas. These areas are often names for zip code locations. For example, the standard city name for several unincorporated areas near Clarence was “Harris Hill.” Geocoding Results. Of the 13,438 records in the original survey database that were exported for geocoding, 13,077 records were successfully geocoded (94.8%) to the (TAZ) and/or XY coordinates. This was accomplished after the completion of four automated processing passes of the survey data. Database Expansion Procedures. In order to simulate actual traffic volumes in the region, the “raw” survey data (the data from completed surveys) was “expanded” to closely approximate the actual traffic counts that were observed on the day the survey was administered. Twenty-four (24) hour automatic traffic recorders (ATR’s) installed during the survey period collected the base data for expansion purposes. The expansion procedures involved calculating the ratio of the number of vehicles that passed through each station to the number of vehicles surveyed during each hour each station was operational. The ratio was used as a weighting factor by StatPac for Windows to generate an “expanded” database that closely approximated the actual traffic volumes observed on the day the survey was administered. The “expanded” database was used for all of the analysis contained in this report. StatPac for Windows created the expanded database by weighting the records in the “raw” database based on the hourly ratio of the actual traffic volume to the actual number of vehicles that were surveyed. For example, if the ratio of the number of vehicles that passed through the survey station during a given hour was 4 to 1 (meaning 25% of the vehicles were stopped and interviewed at that site), StatPac for Windows created an “expansion” weighting of four (4). That number then became the record multiplier and meant that each survey record in that time period actually represented the tripmaking behavior of four vehicles. This process was repeated for each hour that the survey was in operation. Since the survey was not administered for safety reasons between 4:45pm and 7:30 a.m. (due to the lack of daylight), the data from the non-peak hours of 10am-3pm was used to generate data for the hours of 6pm to 7am. The data from 7:30am-9am was used to generate the data for 7am9am; the data from 4pm-4:45 pm was used to generate the data for 4pm-6pm. The weighting factors used for each station are shown in the individual station summaries at the end of this report.

Executive Summary
Percentage of Drivers Who Were Residents of Erie or Niagara Counties: The survey results indicate that the overall population of Erie and Niagara counties increases by approximately 10,937 per day because of trips generated by persons who are not residents of the region. This occurs because the number of persons entering the region on highways that were included in this study exceeded the number of residents who were leaving the region. This observation does not take into account the effects of the NYS Thruway nor of the international bridge crossings with Canada. These impacts will be dealt was as independent projects. The mean vehicle occupancy for the 27,600 non-resident vehicles entering the study area on the eleven highways included in this survey was 1.37 persons per vehicle or 37,812 persons per day. Overall, 55% of the vehicles entering the region were driven by persons who were not residents of Erie or Niagara counties. The mean vehicle occupancy for the 20,833 resident vehicles leaving the study area on the eleven highways included in this survey was 1.29 persons per vehicle or 26,875 persons per day. Overall, 45% of the vehicles exiting the region were driven by persons who were residents of Erie or Niagara counties.
