RESEARCH PROPOSAL

Spatial Decision Support System for Managing Vehicle Crashes

NAME:

INSTITUTION:

Spatial Decision Support System

Introduction

Spatial decision support systems are computerized systems designed explicitly to provide the user with a clear decision making environment to facilitate geographical information analysis in a flexible way (Keenan, 2003). (Densham, 1991) The best road management SDSS systems should have data management system that holds and handles the geographical information/data (Geographical Information System. GIS contains data on road network and is used to help in giving the alternative route from the current position of a driver as well as assist the police to locate the car crash scene), potential model library that can be used in forecasting the possible outcomes of the decision and an interface to help the users in interacting with the computer system and help in analyzing the outcomes. Radar and image sensors can be incorporated in this system to help the drivers (Christine, 1991).

Analysis of traffic vehicle crashes is complicated because it shares areas such as human behavior, engineering and geography (Mahmud & Ehsan). This therefore calls for a systematic approach which automatically senses statistically crucial spatial vehicle crash incidents and give repeatable outcomes. Implementation of effective and efficient traffic crashes counter-measures, needs identification of vehicle crash prone locations and analysis of crash patterns in each location. A model method can be used to give data on involvement and occurrence of road accident. Measurement of every 500 meter section of the highway will be done to give data on geometry.

 

Research Objectives

This research aims to determine the reasons why vehicle crashes are high, give the appropriate system to be installed to reduce the causes and answer the following queries:

1. What are the main causes of vehicle crashes?
2. How does the road geometry contribute to vehicle crashes and what needs to be done?
3. What is the best spatial decision support system needs to be installed to curb vehicle crashes?

Methodology

The system should contain a module that will operate as a real time system for monitoring. It will start with collection of field data to act as the client. The data related to road traffic crashes can be categorized into non-spatial and spatial data which should be put into one database. This data will be transferred to the data house ware via the internet by use of GPRS or the WiMAX. The data house ware will consist of different data sources, map data which involves roads networks and description data from the data center. Integrated data from the data house ware will be used by the main system to analyze it and achieve different statistical reports which can be change and improved by use of different elements through the interaction of the designed graphic user interface.

When an vehicle crash occurs the citizens will be able to provide the information to the main system by use of wireless internet protocol. The system should be able to communicate with the nearest police station through the internet and suggest the best path to it through the available traffic data.

Results and discussion

The system will be developed to use online communication through wireless means. The drivers to use this will require wireless communication devices. The system will be able to provide alternatives to the users of the road where the accident has occurred with the aid of geographical information system.

Conclusion

This research aims to come up with a system to cover, vehicle crash analysis and management, diagnosis of accidents, reduce accidents and increase road safety. The roads should be grouped in form of zones to ease the process.
