We need answer user's request: produce HTML fragment only, no explanation. Need parse image OCR. Need obey strict constraints. Need output starts with

page title? The page has header "GDHS-6-E1—November 2013*" maybe page header? Filter says page header/footer ignore. But output must start with

(page title). There is no page title except maybe table? Need likely use

GDHS-6-E1—November 2013*

? But header ignored? Rule 9: each page output must start with

(page title). If no page title, maybe use document title? The image top has "GDHS-6-E1—November 2013*" likely header, but filter says page header ignore. However must start with h2. Could use

GDHS-6-E1—November 2013*

as page title? It's not page header? It's centered title. Need include? Maybe yes. Then table with Page, Existing Text, Corrected Text. Need represent table. Need formulas? There are equations with fractions. Allowed tags include p, span, em, sup, sub, pre/code, formula. No style. Need represent math as text? Could use

L = V^2 / [254(R ± G)] ...

. But table cells can contain p/formula. Need avoid unsupported tags. Use table with caption? The table has headers Page, Existing Text, Corrected Text. Could use ... Need preserve strikethrough? Original has strikethrough on some text? In image, some text has strikethrough? It appears some words are struck through? Let's inspect. Existing Text: "43 km/h [26 mph]. This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,500 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,500 ft], for which the speed is about 43 km/h [26 mph]. Figure 3-24 shows the performance on grade for a truck that approaches the grade at or below crawl speed. The truck is able to accelerate to a speed of 40 km/h [25 mph] or more only on grades of less than 3.5 percent. These data serve as a valuable guide for design in appraising the effect of trucks on traffic operation for a given set of profile conditions." Some words maybe underlined? In corrected text: "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]. This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,700 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,700 ft], for which the speed is about 43 km/h [26 mph]. Figure 3-25 shows the performance on grade for a truck that approaches the grade at or below crawl speed. The truck is able to accelerate to a speed of 40 km/h [25 mph] or more only on grades of less than 5.5 percent. These data serve as a valuable guide for design in appraising the effect of trucks on traffic operation for a given set of profile conditions." There are strikethroughs? In corrected text, "2,700 ft" maybe underlined? Actually image: [2,700 ft] maybe underlined? [3,700 ft] underlined? "5.5 percent" underlined? Existing text has [2,500 ft] underlined? [3,500 ft] underlined? Figure 3-24 underlined? 3.5 percent underlined? Need maybe use for underlines. Some text in corrected has strikethrough? Let's inspect: In corrected text: "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]. This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,700 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,700 ft], for which the speed is about 43 km/h [26 mph]. Figure 3-25 shows the performance on grade for a truck that approaches the grade at or below crawl speed. The truck is able to accelerate to a speed of 40 km/h [25 mph] or more only on grades of less than 5.5 percent. These data serve as a valuable guide for design in appraising the effect of trucks on traffic operation for a given set of profile conditions." Some words maybe have strikethrough? The image has some words with line through? For example "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]." maybe no. "This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,700 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,700 ft], for which the speed is about 43 km/h [26 mph]." There are underlines under [2,700 ft], [3,700 ft], 5.5 percent. Existing text underlines [2,500 ft], [3,500 ft], Figure 3-24, 3.5 percent. Could use . Need not overdo if uncertain.

Rows:

- Row with no page label? It seems first row spans? The table has Page column blank for first long text? Actually top row after header: Page blank? Existing Text starts at top, Corrected Text starts at top. Then next row Page 3-147, Existing Text "Equation 3-39 is shown as" formulas, Corrected Text "Please change Equation 3-39 to read" formulas. Then Chapter 4 row? Page column "Chapter 4" maybe section heading in Page column? Then row 4-2. Then Chapter 5 heading. Then row 6-13. Then Chapter 9 heading. Then row 9-12. Need represent as table rows. Could have rows with Page cell containing "Chapter 4" and other cells empty? Or use table with rows:

then ... But maybe better preserve layout. Need no empty cells? Allowed. Could use . Need avoid blank? okay.

Need formulas. Original:

Equation 3-39 is shown as

L = V^2 / [254(R ± G)] for the Metric units and as

L = V^2 / [30(R ± G)] for the U.S. Customary units.

Corrected:

Please change Equation 3-39 to read

L = V^2 / [254(R ± G)] for the Metric units and

L = V^2 / [30(R ± G)] for the U.S. Customary units.

Need represent fractions. Could use

L = V^2 / [254(R ± G)] ...

. But formula class allowed. Could use sup for V^2: V². Use ±. Use parentheses. Need maybe preserve line breaks? Use separate

for each equation. In table cell, multiple p okay. Need no style.

Need page footer copyright ignored. Page number? There is no page number? Bottom copyright. Rule says page number placeholder 4 at end. Need output

Need start with h2. Could use

GDHS-6-E1—November 2013*

. But header ignored? If ignore, no h2. But must start h2. Maybe use

Errata

? Not in image. Better use visible title as h2. It is centered at top, likely page header but also title. Use h2.

Need table caption? Could use

but empty cell may be okay. Could use ? Empty p maybe not. Use .

Potential issue: The top title is a page header and should be ignored, but must start h2. Could maybe use

Errata

but not in image. Use title.

Need maybe include "GDHS-6-E1—November 2013*" as h2 with class align-center. Good.

Need final only HTML. Ensure no analysis in final.

Double-check allowed tags: p, h2, h3, h4, h5, strong, em, b, i, u, s, sup, sub, table, caption, thead, tbody, tfoot, tr, td, th, ol, ul, li, blockquote, span, pre, code, hr, br. We use h2, table, thead, tbody, tr, th, td, p, u, sup. Good.

Need maybe no class on h2? align-center allowed. Good.

Need maybe no

inside th? We use text. Good.

Need maybe no empty td? allowed.

Need maybe preserve "3-147" as page. Good.

Need maybe preserve "Chapter 4" as row. Good.

Need maybe use

in td for chapter rows. Good.

Need maybe use

for empty? no.

Need maybe if table cell has multiple paragraphs, okay.

Need maybe formula fraction: original has V^2 over denominator. We use slash. Could use but not needed. Could use

L = V² / [254(R ± G)] ...

. Good.

Need maybe use parentheses exactly: [254(R ± G)] and [30(R ± G)]. Good.

Need maybe use "for the Metric units and as" in existing. Good.

Need maybe corrected: "for the Metric units and" no as. Good.

Need maybe "Please change this cross reference to Tables 6-3 and 6-4." Good.

Need maybe "attached page" singular. Good.

Need maybe "revised figure." Good.

Need maybe "design speeds shown in U.S. Customary units in Figure 9-18 are incorrect." Good.

Need maybe "Figure 9-18" underlined. Good.

Need maybe "Figure 4-1" underlined. Good.

Need maybe "Section 6.3.1" underlined. Good.

Need maybe "Tables 6-2 and 6-4" underlined. Good.

Need maybe "Tables 6-3 and 6-4" underlined. Good.

Need maybe "Equation 3-39" underlined. Good.

Need maybe "Figure 3-24" underlined. Good.

Need maybe "Figure 3-25" underlined. Good.

Need maybe "3.5 percent" underlined. Good.

Need maybe "5.5 percent" underlined. Good.

Need maybe first corrected sentence underlined entire. If not, okay. Could be too much. But likely changed text. Use around entire sentence. Need ensure punctuation inside u? Yes.

Table? There is no caption. Could omit caption. Table headers th. Need maybe class layout-columns? No, actual table. Use .

Need ensure no prohibited tags. Use only allowed. No style. No nbsp. No multiple spaces. Need avoid consecutive spaces. Use single spaces. Need no Markdown. Need correct nesting.

Need decide if use for strikethrough? The image maybe has strikethrough? Let's inspect carefully. The text in corrected column: "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]. This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,700 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,700 ft], for which the speed is about 43 km/h [26 mph]. Figure 3-25 shows the performance on grade for a truck that approaches the grade at or below crawl speed. The truck is able to accelerate to a speed of 40 km/h [25 mph] or more only on grades of less than 5.5 percent. These data serve as a valuable guide for design in appraising the effect of trucks on traffic operation for a given set of profile conditions." Some words have underline, not strike. Existing text: "43 km/h [26 mph]. This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,500 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,500 ft], for which the speed is about 43 km/h [26 mph].

The truck is able to accelerate to a speed of 40 km/h [25 mph] or more only on grades of less than 3.5 percent. These data serve as a valuable guide for design in appraising the effect of trucks on traffic operation for a given set of profile conditions." Underlines under [2,500 ft], [3,500 ft], Figure 3-24, 3.5 percent. Could mark with . Need maybe "3-147" row: Existing Text "Equation 3-39 is shown as" then formulas. Corrected "Please change Equation 3-39 to read" then formulas. Underline? "Equation 3-39" maybe underlined? In image, "Equation 3-39" underlined? It appears underlined? Existing: "Equation 3-39 is shown as" maybe "Equation 3-39" underlined? Corrected: "Please change Equation 3-39 to read" maybe "Equation 3-39" underlined? Could use Equation 3-39. Also "Figure 4-1" underlined? "Figure 4-1 incorrectly labels the traveled way and the roadway." Maybe Figure 4-1 underlined. "Section 6.3.1" underlined? "Tables 6-3 and 6-4" underlined? "Figure 9-18" underlined? Need use for underlined terms.

Need preserve "GDHS-6-E1—November 2013*" with em dash? Use —. Need maybe asterisk.

Need table row for first long text: Page cell empty? Could use

. But maybe the first row is continuation from previous page? Page column blank. Use . Need no empty? okay.

Need chapter headings in Page column: Could be

. But maybe they are section headings spanning all columns? In table, "Chapter 4" appears in Page column only, with blank other columns. Could use . Or use ? But Page column heading? It appears left aligned under Page, not spanning. But visually it's a row label. Could use . Need preserve numbering.

Need row 4-2: Existing Text "Figure 4-1 incorrectly labels the traveled way and the roadway." Corrected "Please substitute page 4-2 with the attached page that includes the revised figure." Underline Figure 4-1? Use Figure 4-1.

Row Chapter 5:

Row 6-13: Existing "Under Sight Distance, the final subsection of Section 6.3.1, the final sentence references Tables 6-2 and 6-4." Corrected "Please change this cross reference to Tables 6-3 and 6-4." Underline "Under Sight Distance"? It appears underlined? In image: "Under Sight Distance" maybe underlined? It is a section title? Could use Under Sight Distance. "Section 6.3.1" underlined? "Tables 6-2 and 6-4" underlined? Corrected "Tables 6-3 and 6-4" underlined? Use for underlined.

Row Chapter 9:

Row 9-12: Existing "The design speeds shown in U.S. Customary units in Figure 9-18 are incorrect." Corrected "Please substitute page 9-12 with the attached page that includes the revised figure." Underline Figure 9-18? Use .

Need formulas in table cells. Could use

L = V² / [254(R ± G)] for the Metric units and as

but formula class maybe for independent formula line. The text "for the Metric units and as" is not formula. Could separate:

L = V² / [254(R ± G)]

for the Metric units and as

. But original line has formula and text same line. Could use

L = V² / [254(R ± G)] for the Metric units and as

. It's okay? formula class for independent formula line, but includes text. Maybe better:

L = V² / [254(R ± G)]

for the Metric units and as

. But then line break. Accept. Need preserve "and as" maybe. For corrected: "for the Metric units and" then formula then "for the U.S. Customary units." Could do:

L = V² / [254(R ± G)]

for the Metric units and

L = V² / [30(R ± G)]

for the U.S. Customary units.

But original has "for the Metric units and as" in existing. Need exact: Existing: "L = V^2 / [254(R ± G)] for the Metric units and as" then next line "L = V^2 / [30(R ± G)] for the U.S. Customary units." Could output:

L = V² / [254(R ± G)] for the Metric units and as

L = V² / [30(R ± G)] for the U.S. Customary units.

This is okay. Corrected:

L = V² / [254(R ± G)] for the Metric units and

L = V² / [30(R ± G)] for the U.S. Customary units.

Need maybe use for inline formula? But formula class okay.

Need avoid multiple spaces. Use single spaces. Need no .

Potential issue: table cells with

inside td allowed? Yes.

Need maybe use

? Not in image. Avoid adding.
Need ensure output starts with
. Could be:
GDHS-6-E1—November 2013*

? Not necessary. But table with headers. Could include

	...	...
Chapter 4
Chapter 4
Chapter 4
Chapter 4			Chapter 5	Chapter 9

...

Need maybe use

for chapter headings? But they are in table cells, not headings. Could not use h3 inside td? Allowed but maybe not. Keep text.

Need consider filter: page header ignored. If we include h2 title, maybe violates filter? But rule 9 requires h2. Could use

Errata

not in image? Don't invent. Use visible title. It's not page footer. Okay.
Need maybe include "Page" "Existing Text" "Corrected Text" as th. Good.

Need check allowed class: align-center, align-right, indent, small-note, layout-columns, formula. We use formula, align-center. Good.

Need no style. Good.

Need no prohibited tags. Good.

Need no ol/ul. Good.

Need no attributes except class, rowspan/colspan. We don't use rowspan/colspan. Good.

Need no h1. Good.

Need no Markdown. Good.

Need no base64. Good.

Need no repeated text. Good.

Need maybe preserve underlines with . Allowed. Need maybe preserve strikethrough? If there are strikethroughs, use . Let's inspect image more: The corrected text first sentence: "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]." There is a line through "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]."? Actually in errata, corrected text may have underlines for changed text, not strikethrough. The image shows some words with underline, not strike. The first line in corrected: "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]." It might have underline under entire sentence? Looking: It appears "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]." has underline? The text has a line under "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]."? In the image, many words have underlines? Let's zoom mentally: Corrected column: first line "entering speed is 60 km/h [35 mph], the" maybe underlined? It shows a line under "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft]"? Hard. Existing column: first line "43 km/h [26 mph]. This is determined by" no underline? Later [2,500 ft] underlined. It seems underlines mark changed values. In corrected, [2,700 ft] underlined, [3,700 ft] underlined, 5.5 percent underlined. Maybe also "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]." is new sentence, maybe underlined? It appears there is a line under "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]." Actually the line under text may be just underline for entire inserted sentence? In errata, corrected text often underlines changed text. The first sentence in corrected is new, likely underlined. But OCR may not need formatting? We can include for obvious underlines. But if uncertain, maybe avoid over-marking. However content rules say faithful. Underline is formatting. Allowed . Need decide.
Let's parse visual: In Existing Text column, there are underlines under:

- [2,500 ft] (line under bracket)

- [3,500 ft]

- Figure 3-24

- 3.5 percent

Maybe also "43 km/h [26 mph]"? No.

In Corrected Text column, underlines under:

- "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft] climb is about 43 km/h [26 mph]."? It looks like a continuous underline from "entering" to "mph]."? The line under first two lines? Let's see: The corrected text first line: "entering speed is 60 km/h [35 mph], the" has underline under entire line? The image shows a line under "entering speed is 60 km/h [35 mph], the speed at the end of a 300-m [1,000-ft]"? It might be underline because it's new text. Then "climb is about 43 km/h [26 mph]." maybe underlined too. Then "This is determined by starting on the curve for a 6 percent grade corresponding to 60 km/h [35 mph] for which the distance is 750 m [2,700 ft], and proceeding along it to the point where the distance is 300 m [1,000 ft] more, or 1050 m [3,700 ft], for which the speed is about 43 km/h [26 mph]." There are underlines under [2,700 ft] and [3,700 ft] only? The rest maybe not. Then "Figure 3-25" underlined? It appears "Figure 3-25" underlined. Then "5.5 percent" underlined. So use for new/changed terms.
But if we mark too much, not harmful? It is formatting. Need not use .
Need maybe preserve "U.S. Customary units" with period. Good.

Need maybe preserve "3-147" row: Existing Text: "Equation 3-39 is shown as" with "Equation 3-39" underlined? In image, "Equation 3-39" appears underlined? It has line under? Yes likely. Corrected: "Please change Equation 3-39 to read" with "Equation 3-39" underlined? Use Equation 3-39.

Need maybe preserve "Chapter 4" etc as plain.

Need maybe use
inside td for paragraphs. For long text, one
per cell. For formulas, multiple
. For chapter rows,
Chapter 4
or just text? In td, can put text directly. But for consistency use
. Allowed. Need no empty p? For empty cells,
okay. Could use . Good.
Need ensure table has no caption? okay.

Potential issue: The top title "GDHS-6-E1—November 2013*" is centered. Use
not align-center? h2 default maybe left. Could use
? Allowed class align-center on h2? It says only these class, not tag-specific. Could use
GDHS-6-E1—November 2013*
. But rule 9 says page output must start with
(page title). It doesn't forbid class. Use align-center to reflect centered. But class allowed. Good.
Need maybe page number placeholder at end:
4
. Good.
Need no comments.

Let's draft HTML. Need be careful with spaces. Use single spaces. Use em dash. Use ±. Use brackets. Use commas.

Table:

3 114	The final paragraph on page 3 114 reads "The effect of rate and length of grade on the speed of a typical heavy truck is shown in Figures 3 24 and 3 25. From Figure 3 24 it can be determined how far a truck, starting its climb from any speed up to approximately 120 km/h [70 mph], travels up various grades or combinations of grades before a certain or uniform speed is reached. For instance, with an entering speed of approximately 110 km/h [70 mph], the truck travels about 950 m [2,700 ft] up a 6 percent grade before its speed is reduced to 60 km/h [35 mph]. If the entering speed is 60 km/h [35 mph], the speed at the end of a 300 m [1,000 ft] climb is about	Please change this paragraph to read "The effect of rate and length of grade on the speed of a typical heavy truck is shown in Figures 3-24 and 3-25.
