Journey to Work Trends Walking
There has been a long-term reduction in walking
trips to work.
4
Journey to Work Trends Bicycling
Limited data points to a rapid increase in work
trips by bicycle.

Journey to Work Trends Public Transportation
Figure 9. Work Trips by Public Transportation,
Northeastern Illinois, 1960-2000
There has been a long-term reduction in public
transit trips to work. Leveling off?

Journey to Work 2000 Snapshot
Driving alone is the dominant mode of journeys to
work, accounting for half of work trips in
Chicago, more elsewhere.

(e.g., walking to a downtown parking garage from
work).

Snapshot of Walking and Bicycling Conditions
Snow Removal
Snow and ice on sidewalks are barriers,
particularly for people with disabilities. Many
communities have regulations or programs to
control snow and ice on sidewalks.

International Comparison of Mode Share and
Traffic Fatality Rates
Table 1 Bicycle and Pedestrian Mode Share and
Traffic Fatality Rates, 2002
From a public health perspective, some nations
with high ped/ bike mode shares have lower
overall fatality rates than the USA.

This chart shows the distributions of the
population and ped/bike injury/ fatality crashes
by age. The chart shows that children are
disproportionate victims.

Non-Motorized and Motorized Trip Injury Collision
Rates by County
Ped/bike and occupant injuryfatality rates per
trip are highest in McHenry and Kane Counties.
High speeds on rural roads may help explain this.

Child/Youth BikePed Crash Rates by Chicago
Community Area, 1994-1996
This map shows the rate of child hospitalization
for ped/bike injuries by Chicago community area.
These hospitalization rates are highly correlated
with poverty and crime. The varying rates partly
reflect different exposure levels.
22
Mapping Pedestrian Crashes
5,077 pedestrian crashes could be geocoded for
2003 Of these, 3153 (62) were in low-income or
minority areas. 1,470 pedestrian crashes for
people aged 5 through 17. Of these, 1075 (73)
were in low-income or minority areas. 525
pedestrian crashes for people aged 5 through 9.
Of these, 428 (81) were in low-income or
minority areas.
