INTRODUCTION
Kittelson & Associates, Inc. is actively working with FMATS to develop an enhanced pedestrian and
bicycle count program. The planned program builds on the existing annual two-hour manual counts
with a system of both permanent and mobile automated counters. These counters would provide
continuous pedestrian and bicycle volume data at locations throughout the city, allowing for a better
understanding of issues such as daily, weekly, and seasonal variations and evaluating project
effectiveness.
PERMANENT AUTOMATED COUNTERS
Permanent counters are placed at high-traffic locations where pedestrians and vehicles are funneled
into a single path. The most established counter technologies for this type of application is a passive
infrared detector for pedestrians paired with inductive loops (either embedded in the pavement or
surface mounted) detecting bicycles.
Figure 1 below shows a passive infrared detector and infrared loops constructed on Anchorage’s
Chester Creek Trail during a repaving project. The detector and loop hardware is mounted in the
adjacent post. Anchorage has recently installed 16 of these counters on their trail system with good
results. Figure 2 shows the surface mount option.

The Chena River Pedestrian Bridge: Due to the concrete approaches to the bridge, a surface
mount induction loop system is recommended. These loops would be placed in the spring and
removed before plowing operations start each year.
The Chena Riverwalk between Peger Road and Moore Street. The asphalt surface allows for
cost-effective embedded inductance loops. The specific location will be selected to minimize
utility conflicts, minimize construction and power costs, and to best capture trail users.

MOBILE AUTOMATED COUNTERS
Temporary, or mobile, automated counters are the same technologies and provide the capabilities of
permanent locations, but allow for the counters to be moved, dramatically expanding the coverage
area of the counters as they can be deployed at several locations over the course of a count season.
These mobile counters are also ideal for project before/after evaluations. Figure 3 shows a mobile
passive infrared counter installed along a trail.
Figure 3 Mobile Passive Infrared Counter
Acquiring two mobile count systems—consisting of passive infrared and surface inductive loop
detectors—is recommended. Two counters would allow for broad coverage as well as collecting data
simultaneously on both sides of a roadway.
COST ESTIMATES
Preliminary cost estimates have been developed for each option and are shown in Table 1. The
installation cost is a planning level estimate; actual installation costs will depend on specific location,
power supply, pavement surface, and other factors. The equipment costs vary by width of detection
zone, induction loop application, and directional count capability. This directional count ability is
recommended as it provides key information on flows and insights into trip purpose and destination.
Pricing information is provided by the vendor and is subject to change.

The PYRO Sensor is equipped with a lens that is sensitive to changes in infrared radiation allowing
the system to detect the presence of a human body passing through its field of view. This sensor
will count pedestrians and cyclists without distinction. The narrow field of view allows the system to
count two people following each other closely. The system is capable of detecting the direction of
travel of pedestrians and cyclists (optional feature). The battery will last for 10 years without
needing to be charged.

The PYRO sensor is our most versatile counting system. It is ideal in many environments including:
• Sidewalks
• Pedestrian malls
• Park entrances
• Trails
3
In many natural settings, a wooden post can be a great way to camouflage the sensor. This post
houses the PYRO sensor and is easy to install. The data logging components and battery are
housed in a hidden, buried manhole adjacent to the trail.
It is possible to purchase an all-in-one wooden post that houses both the sensor and the counting
components for an additional $225. This housing option can simplify installation and ensure
wireless data transmission even when the ground is covered with rain or snow accumulation.
4
With this system, the PYRO sensor and components are housed in an ultra-strong, metal, vandalproof post which is affixed to the pavement. This post is designed to blend into the urban
environment. Color customization is available for an additional charge.
This option is typically used where there is no post to mount a PYRO-Box. As with the PYRO-Box,
this option is particularly resistant to vandalism.
5
With this system, the PYRO sensor and all related components (data logger, battery, and modem)
are housed in a vandal-proof box. The advantage of this housing option is that the installation is
easy enough that it can be installed permanently or moved from location to location.
For better integration into the environment, color customization is available for an additional
charge.
6
The ZELT inductive loop technology makes it possible to analyze the electromagnetic signature of a bike
by detecting each wheel. The frame of the bicycle is not analyzed, therefore carbon fiber bike frames
with metal wheels are detected as well.
Using 13 differentiation criteria, the ZELT technology is able to detect the passage of a cyclist by
distinguishing this signal from that of a motorized vehicle. The ZELT technology is unique and uses a
sophisticated algorithm to ensure unparalleled accuracy in any environment (shared lanes, bike lanes,
protected bike paths, greenways, etc.).

The inductive loops can be installed on any surface including asphalt, concrete and soil. Please
provide us with as much information as possible about your counting site (dimensions, type of
cycling facility). This will help ensure that we provide you with an appropriately calibrated system.
Installations on pavement involve cutting into the
path to lay the loops and burying a manhole
containing
the
counter’s
data
logging
components and battery.
Installations in natural soil involve digging a
shallow trench into the path in order to lay the
ZELT loops for bicycle counting and burying the
manhole to the side. Preformed loops (as seen
below) are provided for natural soil – they greatly
facilitate installation.
9
This system uses the ZELT inductive loops – however these loops are adhered to the surface of a
path, rather than embedded in the path. This is a semi-permanent solution for counting cyclists
(ideal for counting periods of 3-9 months) and it is only appropriate for bike facilities that are offstreet.
The advantage of this system is that installation is less involved than with the permanent loops.
Please note that the loops will need to be replaced periodically (about once per year) at a cost of
$150 per 5-foot (1.5 m) wide loop.

The MULTI system is capable of detecting different user types and distinguishing between them.
This system combines the PYRO and ZELT technologies to count users while identifying their
mode. This system can generate incredibly useful data: user type as well as user direction (see
graph below). The installation can be done on paved surfaces or natural soil.

This system will differentiate between pedestrians and cyclists. The installation involves cutting into
the path to lay the ZELT loops for bicycle counting. A metal post houses all the system electronics
including the PYRO sensor, ZELT electronics, logger, modem and batteries. The metal post
provided has been specifically designed to blend into urban environments and resist potential
vandalism.

Eco-Counter systems, by default, record in one-hour intervals.
Your project may benefit from more detailed count data as a function of time. If so, a system
capable of counting in 15-minute intervals is available for an additional $200.

Your data is stored on a secure and centralized server. This means no accidentally deleted or lost
data. There are two data transmission options, manually via Bluetooth or Automatic Data
Transmission
The Bluetooth transmission is done by manually accessing the counter on-site and retrieving the
data with a Bluetooth enabled Windows laptop. This system capability comes with every counter
free of charge.
The Automatic data transmission service allows the counters to send out data automatically once
a day. There is no need to physically access the counter. This service can significantly cut down on
operational costs. Along with automatic data retrieval you will also be notified if there are no
counts, low counts or high counts with our Eco-Alert system.
• Modem transmission: $420 per counter, per year
• Modem battery to be replaced every two years

Our web-based software, Eco-Visio, gives you the tools you need
to manage your data. There are many advantages to using webbased software: you can access Eco-Visio via web browser so
there’s nothing to download or install, and your data is safely
secured and centralized on our servers.

Eco-Visio Weather makes it possible to understand the effect of temperature,
wind, rainfall, and snow on cycling and pedestrian volumes. Since EcoCounter has access to weather data from a vast network of weather stations,
weather coverage is excellent. There is likely a weather station near your
counting site. This optional weather feature can be added to any counter.
The graph below shows total user counts by day on a trail in October. The red line indicates
temperature and the blue line indicates rainfall. The weather information in this graph explains why
user volumes dropped from October 10th to October 14th.
