From USDOT (RITA)

• "A cooperative agreement was awarded to
  California Department of Transportation
  (Caltrans) who within the availability of funds
  provided the best value to the Government in
  meeting the goals, objectives and requirements of
  Safe Trip-21."

5
Discussion of SAFE TRIP-21 Approach

• Ramifications on
• Our Region Research Questions Addressed
• VII California Testbed
• Broadened in visibility, extent, multi-band
  capability, duration and application users
• Vehicle OEM Laboratories
• Our Activities

6
RSE Installations

• 30 locations (20 intersections, 10 freeway
  sites)
• Original goal was to do it in two months starting
  in June, new starting date is June/July
• Emphasis will be on expanding the existing
  testbed by populating it with more RSEs
• Some of existing RSEs will be retrofitted
• Locations outside the current testbed will be
  considered
• Used latest version of MCNU, new GPS, and new
  WiFi
• California / ECR was retrofitted this past
  Saturday (more later)

7
RSE Installations (cont.)

• Installations will be done by a subcontractor
  (not Caltrans)
• Sole source justification submitted
• Subcontractor has extensive experience working
  for Caltrans and PATH
• Subcontractor will obtain all the required
  permits to work on Caltrans Right-of-Way
• Subcontractor is ready to start pending
• Contract Progress
• MCNU availability Hardware (including Power
  Supplies) Software issues need to be solved
  before installation
•  

8
RSE Installations (cont.)

• The recommended list of first 5 new
  installations
• 1. Marsh Road US 101
• 2. University  US101
• 3. Matadero ECR
• 4. Cambridge ECR
• 5. Embarcadero ECR
• The above list is based on the following
  Stanford Margeurite Shuttle route (as a possible
  probe), location of existing RSEs, proximity to
  current VII California Test Bed, and site surveys
•  

9
California / ECR Intersection
10
California / ECR Intersection
11
California / ECR Intersection

• Done on 5-31-2008 by Caltrans Maintenance and
  PATH
• It is working
• It will be used to serve as a test RSE for the
  next 30 installations with new MCNUs

12
POC Testing
13
VII CA SDN Network Access Point

• Server equipment delivered
• DS3 line installed
• Cisco network equipment delivered
• Securent license ordered May 13
• Notified Cisco April 24
• Received vendor (ATT) quote May 9
• Promised ship date in late May
• Checkpoint Firewall
• Original order in April
• Confusion with vendor led to original delivery
  date quoted as May 12
• Vendor promised June 4 ship date

14
VII Tolling Status

• RSE installed
• LTP (Lane Transaction Processor) being shipped
• Mark IV providing support for LTP
• Changes will be made to support MTC Tolling
  application
• Application design and development underway

15
Dumbarton RSE Installation

MCNU and the NEMA enclosure Space available to
place LTP
Local Transaction Processor Not yet installed
16
Dumbarton RSE

The Dumbarton RSE Installation The MCNU has
been installed for supporting the tolling
application Build number 1.73232 - Consistent
with the requirement Waiting for backhaul
connection
17
Checklist for LTP-RSE
Responsibilities PATH RSE connected to
backhaul and remote access verified LTP
attached to RSE If LTP to use separate
backhaul, connection and remote access verified
This requires setting IP address on LTP
according to the user manual MARK IV
Remotely access RSE and LTP and configure them
for application usage Install current POC
application as interim means to verify operation
18
OBE for Tolling Application
VII Parvus OBE bench tested A3s being
installed with the VII Parvus OBEs Update
positioning bundle to 1.7.1.1 (?)? After
installation we need to check - connectivity
with the RSE at Dumbarton - GPS alignment
verification
19
Savari On Board Unit GPS Testing
Savari OBU GPS Testing GPS tests done in South
Bay, near US101 utilizing the VIICA test-bed
RSU5. Red dots indicate test vehicle trajectory
and the green dot is the RSU, overlaid on Google
Map. Fairly accurate match with the road was
verified.

UCR HA-NDGPS Implementationand DGPS Evaluation

• Objective Create a HA-NDGPS correction
  equivalent base station and evaluate in
  comparison with alternative DGPS architectures
• L1/L2 CP-DGPS base station with conversion
  software to High Accuracy signal
• Broadcast high accuracy signal over DSRC
  architecture
• Evaluate CP-DGPS performance characteristics with
  alternative methods
• Tasks
• Obtain Hardware/Software
• Trimble 5700, NTRIP, GRIM, HA2RCTM, rover
  receivers
• Set up initial test architectures at UC Riverside
  - POC
• Deploy HA-NDGPS and suitable architecture for VII
  - FOT
• Evaluate and compare HA-NDGPS and alternate
  positioning architectures
• Document DSRC DGPS implementation requirements

23
