crosswalk_traffic_light_estimator

Purpose

crosswalk_traffic_light_estimator is a module that estimates pedestrian traffic signals from HDMap and detected vehicle traffic signals.

Inputs / Outputs

Input

Name	Type	Description
`~/input/vector_map`	`autoware_auto_mapping_msgs::msg::HADMapBin`	vector map
`~/input/route`	`autoware_planning_msgs::msg::LaneletRoute`	route
`~/input/classified/traffic_signals`	`tier4_perception_msgs::msg::TrafficSignalArray`	classified signals

Output

Name	Type	Description
`~/output/traffic_signals`	`tier4_perception_msgs::msg::TrafficSignalArray`	output that contains estimated pedestrian traffic signals

Parameters

Name	Type	Description	Default value
`use_last_detect_color`	`bool`	If this parameter is `true`, this module estimates pedestrian’s traffic signal as RED not only when vehicle’s traffic signal is detected as GREEN/AMBER but also when detection results change GREEN/AMBER to UNKNOWN. (If detection results change RED or AMBER to UNKNOWN, this module estimates pedestrian’s traffic signal as UNKNOWN.) If this parameter is `false`, this module use only latest detection results for estimation. (Only when the detection result is GREEN/AMBER, this module estimates pedestrian’s traffic signal as RED.)	`true`
`last_detect_color_hold_time`	`double`	The time threshold to hold for last detect color.	`2.0`

Inner-workings / Algorithms


start
:subscribe detected traffic signals & HDMap;
:extract crosswalk lanelets from HDMap;
:extract road lanelets that conflicts crosswalk;
:initialize non_red_lanelets(lanelet::ConstLanelets);
if (Latest detection result is **GREEN** or **AMBER**?) then (yes)
  :push back non_red_lanelets;
else (no)
  if (use_last_detect_color is **true**?) then (yes)
    if (Latest detection result is **UNKNOWN** and last detection result is **GREEN** or **AMBER**?) then (yes)
     :push back non_red_lanelets;
    endif
  endif
endif
if (Is there **STRAIGHT-NON-RED** road lanelet in non_red_lanelets?) then (yes)
  :estimate related pedestrian's traffic signal as **RED**;
else if (Is there both **LEFT-NON-RED** and **RIGHT-NON-RED** road lanelet in non_red_lanelets?) then (yes)
  :estimate related pedestrian's traffic signal as **RED**;
else (no)
  :estimate related pedestrian's traffic signal as **UNKNOWN**;
endif
end

If traffic between pedestrians and vehicles is controlled by traffic signals, the crosswalk traffic signal maybe RED in order to prevent pedestrian from crossing when the following conditions are satisfied.

Situation1

crosswalk conflicts STRAIGHT lanelet
the lanelet refers GREEN or AMBER traffic signal (The following pictures show only GREEN case)

Situation2

crosswalk conflicts different turn direction lanelets (STRAIGHT and LEFT, LEFT and RIGHT, RIGHT and STRAIGHT)
the lanelets refer GREEN or AMBER traffic signal (The following pictures show only GREEN case)
