Chapel Hill Transportation Management Plan

2005 Employee Travel Survey Results

 

Introduction and Description

 

The Town of Chapel Hill Transportation Management Plan (TMP) is intended to reduce the use of single-occupancy vehicles and encourage travel by alternative modes of transportation.  The TMP requires the presence of transportation coordinators at each site, annual transportation reports, and a biennial travel survey.  The TMP began in 1991, and now applies to 74 developments containing almost 300 tenants.  It applies to employers in Chapel Hill who are located in developments which have been approved for Special Use Permits.  In addition, the TMP applies to all departments of the Town of Chapel Hill government. 

 

A travel behavior survey is required of each business and all employees at TMP sites.  It asks questions about place of residence, commuting time and distance, transit use, and reasons which may motivate people to change their commuting behavior.  The results of this survey are used to profile the commuters in Chapel Hill and to determine how best to serve their needs.  In 2005, survey packets were sent to 74 sites containing approximately 292 employers and 7,962 employees.  Of the surveys distributed, 153 employer surveys and 3,966 employee surveys were returned.  The employee response rate was 49.8%, slightly below the goal of 50% (See Table 1).

This document is a basic overview of TMP employee commuting behavior reported in the 2005 employee survey.  It also discusses changes in the characteristics of TMP employees and their commuting patterns over time from 1999 to 2005.  Though some data is available from the years 1994, 1995, and 1996, data is available for more than 1000 respondents only for the years from 1999 to present, thus only these years were used for historical comparison.  The growth of the TMP survey as more sites are included means that results from year to year are not directly comparable.  It is also important to note that every question was not answered by all employees therefore the number of respondents may vary between tables.  

 

Place of Residence

 

In 2005, employees at TMP sites commuted to work from 72 different towns in 20 counties.  Ninety-seven percent of these employees commuted to Chapel Hill from Orange County and the neighboring counties of Alamance, Chatham, Durham, and Wake.  Of those employees, 48% commuted from within Orange County, and 33% commuted from within Chapel Hill.  Table 2 shows the most popular residential locations of TMP employees.

The majority of TMP employees commute from locations outside Chapel Hill.  Since 1999, the percentage of employees living within Chapel Hill has decreased by 6%.  The percentage of employees has grown by 2.6% for Durham, 1.9% for Wake County, and 1.1% for areas classified as other.  The percentage of employees living in Carrboro, Hillsborough, Alamance County, and Chatham County have all changed by less than 1%.

Travel Mode

 

Survey results indicate that almost 90% of TMP employees travel to work in a single occupancy vehicle.  This percentage has decreased slightly since 1999, corresponding with an increase in all of the listed alternative modes.  The largest increase is in transit use, which may be due to the fact that the Chapel Hill Transit bus system went fare-free during this time period.

Commute Distance & Time

 

In 2005, almost 40% of TMP employees commuted more than 20 miles one-way to Chapel Hill.  Since 1999, the largest decrease is evident in those employees commuting less than 5 miles.  The largest increase is evident in those employees commuting more than 20 miles.  This shows a general trend towards employees living further from work, which is supported by residential location data.  TMP employees in 2005 were more likely to travel less than 10 minutes or more than 30 minutes to work than previously.  The percentage of employees commuting between 15 and 30 minutes has decreased a great deal.  This seems to show that employees in 2005 were more likely to live either very close to or very far from work than in the past.

Commute Time of Day

 

Survey results show that most TMP employees continue to maintain traditional work days, resulting in clear morning and evening peak travel periods.  However, results also indicate that a majority of TMP employees in 2005 traveled to work outside the hour of 7:30 to 8:30 in the morning.  Other evidence of increased alternative work schedules includes a 10.6% increase in the percentage of employees arriving at work after 8:30 since 1999.

Commuter Behavior Changes

 

In the 2005 survey, 1697 people (61.1%) had never used transit.  Possible reasons for the lack of transit use among TMP employees include the reported data that 839 people did not work and 1694 did not live near a transit stop.  However at the majority of businesses, employee reports regarding transit service contradicted each other.  In these cases, some employees reported that there was not transit service within a 5 minute walk of their work while others reported that there was.  The level of detail provided in the survey is not sufficient to make a determination about the extent to which people’s perception differed from the actual transit presence. However, this shows the need for better information provision in encouraging transit use.  People who do not perceive that they work or live close to transit are unlikely to use those services even if they exist.

 

Determining what incentives could change people’s commuting behavior is important for future efforts to reduce SOV commuting.  Of the TMP employees, 1222 (44.1%) said they would not consider changing their commuting habits at this time.  However, many employees reported that they would be willing to consider changing their behavior for a number of reasons (See Table 8 for full list of reasons).  The largest portion, 945 (34.1%) employees, said that they would consider change their commuting habits if they could save money.  Others said they would consider a change if they could vanpool, had help setting up a vanpool, or had a carpool partner.  More than 200 employees reported that they would be willing to changing if they had more information about transit and ridesharing.  These answers indicate a general willingness by many people to use alternative modes if those modes are made more attractive through information, experience, and monetary savings.

The TMP survey also gathered information about employee activity levels during the workday (See Table 9). More than 16% of employees reported walking or biking on short errands or to nearby meetings.  However, only 6% of employees reported that they walk, bike, or take the bus to lunch during the week.  Though it is uncertain how many employees bring lunch or eat at on-site locations, it is likely that some percentage of employees travel by auto to lunch, adding to mid-day traffic.  Though 11.6% of employees reported using their lunch break for exercise, it is not known what type of exercise that is (i.e. traveling to a gym, exercising on site) Overall, the majority of TMP employees do not walk or bike during the day.

Comparison to UNC and Regional Data

 

Data from recent travel behavior surveys for the Triangle region and for UNC employees can be compared to TMP data to further explore commuting patterns.  The top residential locations for UNC employees are very similar to TMP employees, though a slightly higher percentage of TMP employees reside in Chapel Hill.  Data for the region was not compared due to the large difference in work location destinations for that sample.

TMP employees are less likely to live within 5 miles of their work than UNC employees.  TMP employees are also less likely to live more than 20 miles from their work.  Though travel time data is not directly comparable due to different categories for time, it is notable that UNC employees are less likely to commute less than 10 minutes.  This reflects the fact that UNC employees are more likely to use alternative modes, since modes such as transit have higher travel time than autos.  Detailed data about distance to work was not available from the regional survey, but the average trip distance for Home-based work trips in the region was 9.61 miles.

 

Table 11. Distance to Work for TMP and UNC Employees

 

Mode choice for TMP employees and UNC employees is very different.  Only 69.9% of UNC employees drive alone, compared to 88.3% of TMP employees.  UNC employees are much more likely to use Park and Ride or transit than TMP employees.  A higher percentage of UNC employees uses all alternative modes except carpooling.  The mode choice for TMP employees is quite similar, however, to data for the entire region.  TMP employees were more likely to use transit or walk than regional employees, but percentages for drive alone and carpool were very close to the same values.
