INTRODUCTION
The 1988 Manual on Uniform Traffic Control Devices states:
"Crosswalk markings at signalized intersections and across intersection approaches on which traffic stops, serve primarily to guide pedestrians in the proper paths. Crosswalk markings across roadways on which traffic is not controlled by traffic signals or STOP signs must also serve to warn the motorist of a pedestrian crossing point at non-inter-section locations, these markings legally establish the crosswalk...
"Crosswalks should be marked at all intersections where there is a substantial conflict between vehicle and pedestrian movements. Marked crosswalks should also be provided at other appropriate points of pedestrian concentration, such as at loading islands, mid-block pedestrian crossing, or where pedestrians could not otherwise recognize the proper place to cross...
"Crosswalk markings should not be used indiscriminately. An engineering study should be required before they are installed at locations away from the traffic signals or STOP signs."
This guideline should be used to insure that there is consistency applied statewide when determining the need for crosswalk markings and to insure that sign installation practices are consistent across Vermont when crosswalk markings are determined to be unnecessary.
It must be recognized that not all situations can be adequately addressed in this guideline, therefore, engineering judgement must be used at all times.
Ultimately, it is up to the driving public and pedestrians of all ages to understand current Vermont laws, and thus act accordingly.
It is important that the driver and pedestrian recognize what marked crosswalks can and cannot do. Pedestrians need to know that they should be just as careful in using a marked crosswalk as when using an unmarked crossing area.
This guideline addresses the issues and sign layout requirements for the following situations:
. Traffic Signal intersection control
. STOP sign intersection control
. Uncontrolled approach to an intersection
. School crossing
. Non-intersection crossing or mid-block
. Unmarked pedestrian crossing
MARKED CROSSWALKS
Rules to Implement
Title 19 V.S.A., Section 905b
[See illustration in printed publication.]
CONTROLLED INTERSECTIONS
Traffic Signal Intersection Control
There shall be no signs installed at the marked crosswalks or advance signs placed on the roadway approaches denoting pedestrian activity at the intersection.
[See illustration in printed publication.]
STOP Sign Intersection Control
There shall be no signs installed at the marked crosswalk, or advance signs placed on the roadway approach denoting pedestrian activity at the intersection.
[See illustration in printed publication.]
UNCONTROLLED INTERSECTIONS
Uncontrolled Approach to an Intersection
A crosswalk may be placed at an intersection on a roadway approach that is not regulated by a traffic signal or a STOP if all the following criteria are met:
Regulatory Signs (VR-004a) shall be installed at the crosswalk location and warning signs (W11-2) shall be installed on the roadway approaches as shown on the sign layout detail. Advance warning signs (W11-2) will not be required in urban areas where pedestrian activity is an expected feature of the driving environment.
When installed crosswalks should be placed as close to perpendicular to traffic as possible.
[See illustration in printed publication.]
School Crossing - Non-Intersecting Crossing or Mid-Block.
Crosswalks should be applied at locations on established routes to school where there is conflict between vehicles and school children, or where students would not otherwise know the proper place to cross. There does not need to be a specific number of students. Signs and pavement markings should be installed if all the following criteria are met:
Signs (VR-004a, S2-1) shall be installed at the crosswalk location and a warning sign (S1-1) shall be installed on the roadway approaches as shown in the sign layout detail:
When installed crosswalks should be placed as close to perpendicular to traffic as possible.
[See illustration in printed publication.]
Non-Intersection Crossing or Mid-Block
A marked crosswalk may be used across a roadway if all the following criteria are met:
Regulatory signs (VR-004a) shall be installed at the crosswalk location and a warning sign (W11-2) shall be installed on the roadway approaches as shown on the sign layout detail. The advance warning signs (W11-2) will not be required in urban areas where pedestrian activity is an expected feature of the driving environment.
When installed, crosswalks should be placed as close to perpendicular to traffic as possible.
[See illustration in printed publication.]
UNMARKED CROSSINGS
Unmarked Pedestrian Crossing
When the criteria for a marked crosswalk is not met, warning signs as specified in the MUTCD, (Part II-C), Warning Signs, may be installed.
If signs are determined to be warranted based on available sight distance, the following sign layout detail should be used where applicable:
CASE A
Cases to consider would be on highways adjacent to lakes and ponds, where summer camps and the associated activities occur, or connections for a hiking trail require travel along the roadway.
[See illustration in printed publication.]
CASE B
This situation tends to be seasonal locations or locations of activity during certain days. Cases to consider would be locations where some attraction such as fishing or swimming occur on one side of the highway and parking occurs on the other.
[See illustration in printed publication.]
CASE C
[See illustration in printed publication.]
If this distance exceeds 50 feet, then Case B applies.

STATE OF VERMONT AGENCY OF TRANSPORTATION TRAFFIC & SAFETY DIVISION
CROSSWALK APPROVAL
In accordance with 19, V.S.A., § 905(b), Maintenance District.... is hereby permitted to install a crosswalk on the state maintained portion of .... at the following location:.....;
The approval is contingent upon the installation and maintenance of the crosswalk in accordance with State as shown in the Manual on Uniform Traffic Control Devices (MUTCD), as adopted by State Law Title 23, § 1025.
The Traffic and Safety Division reserves the right to withdraw approval and require removal of this crosswalk based on safety, maintenance and engineering issues, and as future conditions dictate. The appropriate signs shall be in position prior to the crosswalk installation.
