1. A real-time traffic citation risk assessment system comprising:
- an in-vehicle computer coupled to vehicle sensors that sense vehicle position, speed, and operating parameters;
an in-vehicle database comprising vehicle characteristics, vehicle performance characteristics, driver and household demographics, roadway characteristics and roadway operating conditions, environmental conditions, and roadway links that link vehicle position;
software that runs on the in-vehicle computer that determines the relative risk of receiving a traffic citation using predetermined risk functions in real time derived from data in the database and the vehicle sensors; and
an in-vehicle display for displaying the computed relative risk of receiving a traffic citation to the driver of the vehicle in real time.

Abstract
Disclosed are systems and methods for assessing the relative probability that a driver will receive a traffic citation as a function of real-time, monitored vehicle activity within the context of historic spatial and temporal traffic citation data. Exemplary systems and methods determine risk as a function of such factors as (1) local roadway ticket histories, (2) vehicle characteristics, (3) real-time vehicle and engine operating parameters, (4) roadway and intersection design configurations, speed limit and design speed conflicts, and operating conditions, and (5) environmental conditions, for example.

11. A real-time citation risk evaluation method for use in a vehicle, comprising:
-
storing, in the vehicle, vehicle characteristics and vehicle performance characteristics, driver and household demographics, roadway characteristics and roadway operating conditions, environmental conditions, and roadway links that link vehicle position;
sensing, in the vehicle, vehicle position, speed, and operating parameters;
receiving, in the vehicle, prevailing roadway speeds and environmental conditions;
computing, in the vehicle, using predetermined citation risk functions, derived from the sensed vehicle speed and position, received roadway speeds and environmental conditions, and the stored data; and
displaying the computed citation risk to the driver of the vehicle in real time. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
