a prototype of an intelligent roadside safety system

1- Information is collected on scheduled time. 2- Data is transferred to a dispatch center.3- A wide variety of packages are provided.

How to access to the informationAccess could be available to the public by logging into a specially designed website.What users need to possesssmart device or Multi Media Interface (MMI) to load information on it.4- Dispatch center communicates in real-time with the special users and in non-real-time with road usersWhat kind of information can be transferred to the CAD centerAlerts about discrepancy between what is displayed in the car LCD monitor and what the reality is.

Why special usersTo prevent too many false change alerts.Who are special usersDrivers of emergency vehicle and roadway maintenance vehicleHow can special users alert CAD center?Using a button or touch screen on smart deviceWhat if the condition is changed?• The objective system warns fleet operators• Central hardware and software are used to process

observations from on-board smart devices and display them in a format easily recognizable by an operator.

• Alerts are archived in CAD center

Roadside features:Important variables in safety predictionSignificantly impact the frequency and severity of certain road accidentsNational Highway Traffic Safety Administration (NHTSA) In 2003: Roadside objects were involved in 20% of the total roadway fatalities

Roadside features significantly impact the frequency and severity of run-off-roadway crashes. In recent years, roadside futures data are being collected by new remote sensing technologies such as mobile LiDAR. The purpose of this study is to develop an ITS system which communicates with road users to transfer information regarding objects, slopes, and roadside conditions. The proposed ITS system uses roadside inventory data to improve drivers safety during night and other low-visibility conditions.

Lack of the visibility reduce drivers safety. The proposed ITS system can communicate with road users to show information(objects, slopes, and roadside conditions) and improve safety during night and other low-visibility conditions.

In futureNew technology tools could be joined to the current system.Enhancing hardware to collect more accurate dataUpgrading in software to process information faster More detailed information about how this system can come trueEstimating the system’s cost

Hardware: • Mobile Terrestrial Laser Scanner• Hardware used in dispatch center to process the

information• Smart device including LCD Monitor, GPS, and other

devicesSoftware:• Microstation, TerraScan, TOPODOT, TPhoto, Dashmap,

Trimble and ArcGIS 10.1Communication:• Wide area wireless MMI• Fixed point to fixed point Terrestrial

microwave

Why Terrestrial microwaveLower capital cost, more temperature compatibility, no cables needed, availability of multiple channels, and wide bandwidth are some vigorous points of this method.

Mobile Terrestrial Laser Scanning (or Mobile LiDAR)• Uses laser scanner technology in combination

with Global Navigation Satellite Systems (GNSS) and other sensors to produce accurate geospatial data from a moving vehicle

• Applied by DOTs and private contractors.• Thousands of data points are gathered • per second.

How these data are used • In the computer- aided dispatch center (CAD), all the

required data are extracted, unnecessary ones are eliminated, and a “point cloud” data set is generated.
