Map-matched trajectory compression

Journal of Systems and Software, 2013
The wide usage of location aware devices, such as GPS-enabled cellphones or PDAs, generates vast volumes of spatiotemporal streams of location data raising management challenges, such as efficient storage and querying. Therefore, compression techniques are inevitable also in the field of moving object databases.

Evaluation of map-matching techniques

Conference Record of papers presented at the First Vehicle Navigation and Information Systems Conference (VNIS '89), 2003
The authors describe a research and demonstration effort aimed at improving vehicular location accuracy. This effort used a wheel sensor, a gas-rate gyro, a map-matching technique, and beacon information to reduce accumulated errors. The demonstration model showed good location accuracy results in field tests over three courses (one was in an urban ...

A Novel Map Matching Algorithm

Applied Mechanics and Materials, 2014
Presently, most of the researches on Map Matching focus on high sampling rate and accurate GPS points. This paper discusses a challenging problem with low GPS sampling rate and some continuous points with large deviation. To solve the problem efficiently, a novel matching method named F&PT is proposed.

Map matching augmented dead reckoning

36th IEEE Vehicular Technology Conference, 1986
Where am I? Where is my destination? How do I get there? These are questions commonly asked by all drivers. The Etak Navigator is an accurate, low cost and informative vehicle navigation system designed to answer these questions. The Navigator operates on a combination of dead reckoning and map-matching, map matching eliminates the accumulation of ...

Segment-Based Map Matching

2007 IEEE Intelligent Vehicles Symposium, 2007
We address the problem of determining the path of a vehicle on a given vector map of roads, based on tracking data such as that obtained from onboard GPS receivers. We describe a method that is based on a piecewise matching of track segments to map features.

An Improved Map Matching Algorithm

Applied Mechanics and Materials, 2012
Mistakes often occurs in map matching when road condition is complex, especially there is island ring, or exit and entrance of highway, in vehicle navigation system. Wrong map matching will lead to wrong map display and wrong route guidance, thus system gives a bad impact to driver.

Correlation algorithms for radar map matching

1976 IEEE Conference on Decision and Control including the 15th Symposium on Adaptive Processes, 1976
This paper presents results of a theoretical study of a simple radar edge detection correlation approach. Several candidate edge correlation algorithms are described. The paper presents results of a theoretical evaluation of one particular candidate correlation algorithm and verification of the edge correlation concept is provided through a ...

Resource Comparative of Map Matching Algorithm

2019 16th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2019
There are currently many map-matching algorithm. In each algorithm it has own strength that are presented in term of accuracy. In many articles no one will present about resource testing, how much resource are used. In this paper, we purpose the results of Hidden Markov Model, ST-Matching and stMM are the resource utilization be used to calculate the ...

Dimensionality, Map Matching, and Anxiety

Psychological Reports, 1963
By supplementing the theory of human communication with the concept of the dimensions of the cognitive field, three stages of communication or three stages in the matching of the cognitive “maps” of the communicators can be distinguished. Different realms of prediction concerning response to a communication are possible (or impossible) at each of ...

Online Map Matching With Route Prediction

IEEE Transactions on Intelligent Transportation Systems, 2019
Map matching is a procedure that estimates the route traveled by vehicles or people by using observed coordinates. It is an important preprocessing procedure for location services based on global positioning system (GPS) data obtained from probe vehicles.
