II. SURVEILLANCE
TASK
2.16 Microcomputer Model Refinement
During 2001-02, CDTC purchased an
advanced software package to allow CDTC to move from its TMODEL2-based modeling
system. Initial efforts with the new
VISUM software are already underway.
During 2002-03, work included creation and calibration of a 500-zone
VISUM transitional model replicating the geographic detail of the TMODEL2 model. In 2003-04, refinement of the transitional
model to the full Census 2000 geographic detail (900 zones) has taken place,
still using the old STEP model trip generation and trip distribution
formulations. Products of CDTC's enriched NPTS 2001 sample have yet to be received
and are expected in coming months; these will be reviewed for use in refining
the VISUM model. The NPTS information
will be the basis for recalibrating the trip generation and trip distribution
models for the new VISUM representation.
In 2003-04, ITC, the vendor/consultant
for VISUM and VISSIM, assisted CDTC in both development of the regional model
and in training for the microsimulation, VISSIM. ITC is developing a post-processor for VISUM
to replicate CDTC’s STEP model emissions and user
cost modules.
TASK
The every-second-year survey of non-state federal aid
road was completed in 2003. The every-fourth-year
sample survey of non-state, non-federal aid roads (local roads) will be
undertaken in 2004. Annual review of
TASK 2.25 Collection of Transportation Planning Support Data
CDTC continues to use interns for extensive data
collection.
These general tasks will continue in 2004-05, increasing
the Capital District's base of locally-generated travel data and travel
relationships. A small consultant budget
is included to allow for specialized traffic studies (in addition to routine
and special counts by NYSDOT and its consultants.) The consultant effort may include speed
monitoring and speed-delay data collection.
CDTC's add-on to the State University of New
York at
In 2003, CDTC collected speed and delay data on NY5 for
both the BRT and NY5 ITS signal project upon completion of the ITS
implementation. In 2004-05, additional data will be collected after traffic
signal prioritization is implemented.
Comprehensive transit ridership data collection using CDTC’s
FTA budget will rollover to 2004-05 as part of the Transit Development Plan
effort.
TASK 2.28 Census / Household Travel Survey
CDTC's new Traffic Analysis Zone (TAZ) set
was used by the Census Bureau in conjunction with the 2000 Census. The new TAZ
set numbers approximately 900 rather than the traditional 471. This was completed in conjunction with the
Census Bureau's "TAZ-UP" process.
CDTC also participated in the Census Bureau's "WORK-UP" effort
to better define addresses for places of work for the 2001 Journey to Work
files.
CDTC transferred $175,000 of its funds to NYSDOT for use
in the 2001 National Personal Transportation Study (NPTS) allowing for
approximately 1800 data samples in the Capital District. This will save CDTC approximately $50,000
from estimates made for the cost of a household travel survey. It will also allow for consistency in data
with the national data base and allow for maintenance of Capital District
travel parameters in 2005 through tracking of national trends. Along with this approach, CDTC will
tentatively plan to repeat the large scale sample again in 2010. Additional results of the Census
journey-to-work data were received in 2002 and 2003; zonal-level information
and the NPTS data are expected in 2004.
During 2002-03, CDRPC reviewed its population
projections and estimates against initial rollout of 2000 Census counts. In 2003-04, 2040 forecasts were prepared to
help guide New Visions work. Estimates
were refined for TAZ's and projections updated for
minor civil divisions. CDRPC plans to
pursue an effort to refine regional economic and demographic indicators for
ongoing monitoring of conditions.
TASK 2.29 Regional Geographic Information System
This task is designed to
permit the continued creation, modification, conversion, and maintenance of map
features and data in conjunction with CDRPC’s
NYSDOT-based regional GIS effort. CDRPC
will continue to process and manipulate data and clip the information specific
to the Capital Region and the communities within its jurisdiction.
For 2004-05, CDRPC will
continue to incorporate parcel-level data and high-resolution orthophotography for the entire region and add this
information to data coverages on the GIS.
The CDTC staff continues to make its
own contributions to the regional GIS.
Numerous GIS applications included drafts of the regional trails map,
scenic byways maps, bike and pedestrian crash data maps and support mapping for
various studies.
CDTC's Civil Rights and Environmental
Justice work will continue to be a major GIS product of 2004-05, along with
Safety Management System work. GIS will
also play a larger role in the New Visions 2030 / New Visions for a Quality
Region effort than was possible in the previous New Visions processes.
TASK 2.31 Traffic
Volume Report
CDTC
continues to maintain a web-available report.
