1. Introduction

The purpose of this document is to define the data fields of Highway and Arterial traffic sensor data.  
 
2. Highway Data 
Highway Data includes two separate files: 
2.1  Highway_Congestion_Config: This file includes the metadata (aka, inventory information) about the highway sensors.  The main objective of maintaining a metadata table is to avoid redundancy. This is because the inventory information of sensors is invariant most of the time, and hence no need to store each time retrieved from sensors. In case a change (e.g., new sensor addition, update on_street information) in the inventory information (as compared to latest inventory) is detected, the change is captured by increasing the config_id in this table. The data is pipe-line ('|') separated. The content of this file is structured as follows. 
 
CONFIG_ID|AGENCY|CITY|to_char(DATE_AND_TIME,'MM/DD/YYYY hh24:mi:ss') |LINK_ID|LINK_TYPE|ONSTREET|FROMSTREET|TOSTREET|START_LAT_LONG|DIRECTION|POSTMILE|AFFECTED_NUMBEROF_LANES 

Example: 1| Caltrans-D7| | 04/05/2011 16:52:09| 716466| highways| I-105| ARDIS| | SDO_GEOMETRY(2001, 8307, SDO_POINT_TYPE(-118.12982, 33.913034, NULL), NULL, NULL)|2| 16.3|3 
 
2.2 Highway_Congestion_Data: This file includes the raw (not processed) data collected from each highway sensor. The content of this file is structured as follows. 
 
 CONFIG_ID|AGENCY|to_char(DATE_AND_TIME,'YYYYMMDD HH24:MI:SS')|LINK_ID|OCCUPANCY|SPEED|VOLUME|HOVSPEED|LINK_STATUS
 
Example:   68|Caltrans-D7|20130309 12:14:11|764115|6|60|10|-1|OK
 
3. Arterial  Data  
Arterial Data includes two separate files:
2.1  Arterial_Congestion_Config: This file includes the metadata (aka, inventory information) about the arterial sensors.  The main objective of maintaining a metadata table is to avoid redundancy. This is because the inventory information of sensors is invariant most of the time, and hence no need to store each time retrieved from sensors. In case a change (e.g., new sensor addition, update on_street information) in the inventory information (as compared to latest inventory) is detected, the change is captured by increasing the config_id in this table. The data is pipe-line ('|') separated. The content of this file is structured as follows. 
 
CONFIG_ID|AGENCY|CITY|to_char(DATE_AND_TIME,'MM/DD/YYYY hh24:mi:ss') |LINK_ID|LINK_TYPE|ONSTREET|FROMSTREET|TOSTREET|START_LAT_LONG|DIRECTION|POSTMILE|AFFECTED_NUMBEROF_LANES
 
Example:   16|Caltrans-D7||06/09/2013 23:49:30|12490-7-0|arterial|Azusa Ave|Puente Ave||SDO_GEOMETRY(2001, NULL, SDO_POINT_TYPE(-117.90785, 34.083375, NULL), NULL,NULL)|130|0|2
 
2.2 Arterial_Congestion_Data: This file includes the raw (not processed) data collected from each arterial sensor. The content of this file is structured as follows. 
 
LINK_ID|CONFIG_ID|AGENCY|to_char(DATE_AND_TIME,'YYYYMMDD HH24:MI:SS')|OCCUPANCY|SPEED|VOLUME|HOVSPEED|LINK_STATUS
 
Example:   80061|14|LADOT|20120130 18:49:12|3|21|2|-1|OK
 
 

IMSC received funding from Oracle Labs to continue on Vehicle Routing Problem in Time-dependent Road Networks research. The main objective of this project - in collaboration with Oracle Spatial research team -  is to investigate efficient algorithms for route planning of delivery vehicles utilizing real-time and historical traffic sensor data.

CALTRANS Funds Transportation Project

Monday, 10 November 2014 16:57

IMSC received funding from California Department of Transportation (CALTRANS) in collaboration with METRANS Transportation Center to  investigate the impact of the accidents on road networks.

ClearPath, a next-generation navigation application developed at IMSC, received funding from group of Angel investors and is licensed from USC. ClearPath is a result of leading Big Data research at IMSC. ClearPath  - granted 3 (2 issued and 1 pending) patents - provides the least time-consuming paths for drivers by adjusting to predicted and real-time  traffic.
