Mitigating
Congestion in the Region
Recently
released American Community Survey by the U.S. Census Bureau showed that
Americans spent an average of 24.3 minutes commuting to work in 2003.
This adds up to more than 100 hours annually for the morning
commute. New York reported the longest average commute-to-work time at
30.4 minutes (38.3 minutes in New York City), followed by Maryland at 28.5
minutes. The ACS data showed that more than 4.7 million of New York’s 8.3
million workers, age 16 and over, drive alone to work, while 2.1 million
commute to work using public transportation. The data also showed that
655,866 used carpools; 423,630 walked to work; 278,761 worked at or from
home; and 76,629 used other means. In New York City, 5.6% of commuters
reported spending more than 90 minutes commuting to work. It is
quite evident that congestion in the U.S. continues unabated, with single
occupant vehicle commuting (as a percentage of all commuting in the U.S.)
moving ever closer to 80%. The only positive trend is in telecommuting
which at 3.5% in 2003 is showing an increase from 3.2% in 2000.
The new Urban
Mobility Report by the Texas Transportation Institute shows that the cost
of congestion in 85 of the largest urban areas in the U.S. reached $63.1
billion in 2003. The report showed that congestion caused 3.7 billion
hours of travel delay and 2.3 billion gallons of wasted fuel. This meant
an increase of 79 million hours and 69 million gallons respectively over
the year 2002. The average annual delay per individual using motorized
transportation grew from 16 hours in 1982 to 47 hours in 2003. The report
also found that if public transportation service was discontinued and
riders traveled in private vehicles, delay would increase by an additional
27%, and congestion costs will increase by an additional $18 billion per
year. (See http://mobility.tamu.edu
for the 2005 Urban Mobility Report).
The New York
metropolitan area is intensively pre-occupied with tackling the congestion
issue, in the effort to improve mobility and achieve desired air quality
standards. It is true that New York City’s bus system (the hub of the
metropolitan area) has experienced significant increase in ridership over
the last eight years, but the issues of reliability, delay, and slow bus
speeds remain a challenge. While the transit systems investigate mobility
enhancement and improvements to address reliability and delay, they will
rely on area employers to implement some TDM measures to help alleviate
the congestion. The Texas Transportation Institute has assembled
summaries of demand management measures that can easily be implemented by
area employers, two of which are reproduced here – Alternative Work
Hours and Telecommuting.
A) Alternative Work
Hours
Description
Flexible work hour programs
allow employees to work a schedule within a range of time periods. For
example, employees may be allowed to work an eight-hour shift starting
between 6 AM and 9 AM and ending between 3 PM and 6 PM. Some programs
allow participants to shift their schedule on a day to day basis, while
other programs require that participants work a selected schedule on a
routine basis. This flexibility allows employees to shift trips to and
from work either before or after the peak hour. Staggered work hour
programs vary the arrival and departure times of groups of employees
within a company before and after the typical 8 AM to 5 PM schedule. The
term ‘staggered’ indicates that employees arrive in different shifts at
different times within a time period. Unlike flexible work hours,
employees in a staggered work schedule may have no ability to choose which
shift they work on. Compressed workweek schedules typically involve
longer, but fewer, workdays (e.g., 10-hour, 4-day workweeks). Compressed
workweeks are advantageous in two ways. Days of commuting and commute
trips are eliminated and longer work days require the employees to arrive
earlier and leave later, removing trips from the peak hours.
Target Market
An increasing number of
businesses are candidates for alternate work hour strategies. As
electronic communication technology improves and computers become more
available at home and office, new segments of the economy have the
possibility of using the flexibility they provide. Staggered work hours
are advantageous for large companies or plants to alleviate onsite
crowding at entrances/exits, parking areas, or elevators. Staggered work
hours work well for assembly line type operations where the beginning and
end of work shifts can be easily managed. Flexible work schedules work
especially well for persons that work independently.
Benefits and Costs
In Bishop Ranch,
California, 14,800 employees took part in a flextime program as part of a
required trip reduction program. The percentage of employees arriving
before 7 AM increased from 8 to 17 percent, while the percentage of
employees arriving after 9 AM increased from 1 to 9 percent. The City of
Berkeley reported that its flextime program reduced annual overtime costs
by $18,000 and sick leave costs by $26,000. Similarly, the Pacific Gas and
Electric Company of San Francisco reported that its flextime program
reduced sick leave costs by $20,000 and resulted in savings of $46,000 in
decreased use of work time for personal business. Several studies in the
1970s in New York and Ottawa, Canada showed that staggered work hours can
smooth out the peaking characteristics of arrivals and departures for work
trips. The Ottawa study involved 33,000 government employees (47 percent
of downtown employees) using a combination of staggered work hours and
flexible work hours. A study showed the morning peak 15-minute arrivals
were reduced by approximately 50 percent and the evening peak 15- minute
departures were reduced by approximately 57 percent. In a 1992 study in
Denver, a total of 9,000 federal employees in 42 agencies participated in
a 4-day, 10-hour compressed work week program. The maximum percentage of
arrivals in any one half-hour period decreased from 56 percent to 42
percent. The maximum percentage of departures in any one half-hour period
decreased from 47 percent to 34 percent.
B. Telecommuting
Description
Telecommuting allows
workers to either eliminate a commute trip all together by working from
home or to reduce trip length by working from a satellite office.
Telecommunications and computers have made it possible to reduce trips by
performing a variety of trip purposes over the telecommunications network.
For example, telecommuters can access work files and programs via the
Internet from home. Teleconferencing allows workers at multiple locations
to conduct meetings, shopping can now be done over the Internet, and
banking transactions can be done over the Internet or at automated teller
machines (ATMs). The capability of making electronic transactions either
eliminates trips or reduces vehicle travel.
Target Market
Telecommuting is not an
option in all work positions, but professional and managerial staffs tend
to be the most applicable positions, while business services, wholesaling,
and banking/finance tend to be the applicable industries. The costs of
establishing a telecommuting program are usually minimal as many
individuals have home computers and Internet access. Some telecommuters
are able to do their work without the need for a computer. Satellite
worksites may be owned/operated by a single company or by multiple
organizations. These facilities are typically equipped with computers and
modems to allow workers that would normally travel long distances to be
connected electronically to their offices. While these facilities may be
effective in reducing vehicle miles traveled, they are typically not
effective in reducing emissions from cold starts and may actually increase
vehicle trips as members of rideshare programs or transit may opt to drive
alone to a nearby center. The majority of telecommuters split time
between the home and office. A 1991 US DOT survey of telecommuters showed
that the average total time per week worked at home by telecommuters was
18.6 hours. Approximately 26 percent of the survey participants reported
working at home an average less than eight hours per week.
Benefits and Costs
Improved productivity is
one of the benefits cited as being associated with telecommuting programs.
Control Data Corporation telecommuters estimated their productivity
increased by 35 percent on telecommuting days, while their managers
similarly estimated the productivity improvement at 30 percent. Pacific
Bell managers estimated productivity improvements of 20 percent due to
telecommuting in addition to office space savings. Reduced cold starts,
emissions, and VMT are all benefits of telecommuting. A study of 400 State
of California employees participating in a telecommuting program showed
that on telecommuting days, participants reduced their cold starts by 39
percent, CO emissions by 64 percent, NOx emissions by 69 percent,
particulate matter emissions by 78 percent, and total VMT by 77 percent.
