STRAIGHT LINE DIAGRAMSCreate and View Roadway Information That Meets Your NeedsTransportation departments collect and manage vast amounts of data about the

characteristics and conditions of their roadway networks. With an abundance of

data, your department needs the ability to view it in a useful way. For many years,

transportation departments have used straight line diagrams (SLDs) as a convenient

way to view and analyze data about their roadways.

WHAT ARE STRAIGHT LINE DIAGRAMS?SLDs provide on one page an abundance of information about roadway configura-

tion, inventory, and conditions. SLDs present side-by-side graphic representations

of physical roadway characteristics and occurrences, such as speed limits, bridges,

number of lanes, accident locations, and more (Figure 1). When you juxtapose this

data, you can see correlations, such as speed limits and accident occurrence or

road conditions and traffic volume.

INTERGRAPHS SLD WEB SERVICEAlthough transportation departments have used SLDs for decades, they are

labor-intensive to create and often out of date. Intergraphs SLD Web service cre-

ates SLDs on demand using your departments most up-to-date information. You

simply select a road, choose what data you want to review, and the Web service

does the rest.

The configurability of Intergraphs SLD Web service gives you the information you

need in the way you need it. You can configure the system so the symbology and

data presented meet your requirements (Figure 2). For example, a traffic engineer

can view traffic volumes side-by-side with speed limits, lane widths, and roadway

configuration. A safety engineer can view accident occurrences, severity indices,

speed limits, and traffic volumes at the same time. Any combination of available

data is possible.

Unlike traditional SLDs, Intergraphs SLD can interact with the user. Intergraphs

SLD has tool tips that can provide extra information, such as route names and

pavement types, just by hovering over an item. You can view any row in the

Attribute section in the Plan section just by clicking on its title. You can configure

hyperlinks so a click on an accident brings up its report, or a click on a bridge

brings up its design drawings. The interactivity of Intergraphs SLD makes it much

more than just static information.

SLD FUNCTIONALITY With Intergraphs SLD, you can:

View vast amounts of transportation data in a way that you can easily interpret and analyze

Analyze selected locations along a roadway

View several road characteristics simultaneously and side-by-side

Split carriage-way or lane characteristics so you can view individual data

Identify intersection locations along the road

Provide content for SLD mapbooks for county engineers, consultants, and others

KeY BeNeFITSControl the portion of the road you want to analyze

Break specified road portion into separate pages of a specified range, such as five-mile stretches

Navigate forward and backward between pages

Select which road characteristics to include in the SLD diagram

Configure the system so the symbols used and the colors assigned make the diagram as informative as possible

Interact with the SLD, such as displaying tooltips of each road characteristic, bringing up hyperlinked documents, or zooming in on the diagram to view details

Select any attribute to visualize in Plan View so you can examine it in detail

Our SLD makes use of your existing transportation data, so it is

easy to deploy. The Web service runs on a standard Web server,

and you can easily integrate it with existing Web sites, or imple-

ment it using the provided .NET client application. The flexibility

of Web services means that more users, inside and outside of

your organization, can access this valuable tool.

INTERGRAPH SLD DIFFERENTIATORSUp to date Any view of SLD after data changes will show

updated data.

Flexibility It is much easier to show different data for differ-

ent users, on demand.

Data quality Since the SLDs are automatically derived from

your data, it eliminates errors associated with manually or

semi-manually constructed SLDs.

Much less labor-intensive Compared to most existing

methods, Intergraphs SLD Web service can save you signifi-

cant time.

Wider distribution Since you can view Intergraphs SLDs

with a Web browser, they can be widely distributed without extra

effort and expense (both inside and outside your organization).

User-interface independent Web Service-based applica-

tion allows for integration with existing Web sites, with desktop

geographic information system (GIS) applications, or via a

lightweight client.
