LCQ13: Traffic light countdown device
*************************************
Question:
The Transport Department (TD) installed a new type of pedestrian traffic light countdown device (the new countdown device) at the signalised junction of Tat Tung Road and Mei Tung Street in Tung Chung in 2023 for testing. The new countdown device starts counting down when the "green man" light is on, such that pedestrians can gauge the total time remained of the "green man" light. According to the preliminary data collected from the survey conducted by a local university commissioned by the TD, after installation of the new countdown device at the aforesaid pedestrian crossing, the situation where pedestrians were unable to finish crossing the road before the flashing "green man" light ends has greatly improved. In this connection, will the Government inform this Council:
(1) whether the data obtained so far from the aforesaid test is sufficient to support the authorities' installation of the new countdown devices at more locations; if so, of the list of locations at which the authorities plan to install such countdown devices; if not, the criteria considered by the authorities and the thresholds for taking forward the implementation of such countdown devices;
(2) apart from the aforesaid trial location in Tung Chung, of the signalised pedestrian crossings at which the Government has previously installed other pedestrian countdown devices for testing; whether it will consider implementing the new countdown devices at such signalised pedestrian crossings to expedite the collection of data; if so, of the details; if not, the reasons for that; and
(3) as the Government indicated in its reply to a question from a Member of this Council on July 10 last year that there was no worldwide general consensus on the merits concerning the effectiveness of vehicular traffic light countdown device, and that motorists' responses to the time displayed on the countdown device might be very diverse, resulting in a higher risk of head-rear collision between vehicles, whether the authorities will consider following the testing method adopted for the new countdown device and installing the vehicular traffic light countdown devices at suitable locations for testing, so as to obtain useful data; if so, of the details; if not, the reasons for that?
Reply:
President,
After consulting the Transport Department (TD), my response to the questions raised by the Hon Holden Chow on pedestrian traffic light countdown device (pedestrian countdown device) is as follows:
(1) and (2) In late 2023, the TD installed a new type of pedestrian countdown device at the pedestrian crossing of Tat Tung Road and Mei Tung Street in Tung Chung for testing purposes. The device begins its countdown when the "green man" signal appears, helping pedestrians better assess the total green time remained. The TD collaborated with a local university to evaluate the device's impact and effectiveness on pedestrian behaviour. Results indicate a slight improvement in the number of pedestrians completing their crossings before the flashing "green man" signal ends, compared to previous trials.
To further collect data on the device's effectiveness under varying road conditions, the TD is arranging to expand the trial, selecting 16 additional crossings (locations listed in Annex) for testing that feature diverse pedestrian flows, crossing distances, and local pedestrian habits. This broader trial is expected to yield richer data for assessing the device's performance across multiple scenarios and behaviours. Additionally, four of the trial sites will be equipped with a red-light countdown feature to evaluate its impact on pedestrian waiting behaviour, which will inform the direction of the next phase.
The TD is progressively installing the new pedestrian countdown device at the selected trial sites and will collect and analyse the corresponding data. Preliminary results are anticipated by mid-2026.
(3) The TD has been monitoring the global application and effectiveness of vehicular traffic light countdown devices, evaluating their potential to improve the travelling experience for road users while ensuring safe operation at signalised junctions in Hong Kong. Drawing on the experiences of various cities in the Mainland and abroad, the TD found no prevailing consensus regarding the safety of such devices. A key reason is the varied driver responses - while some drivers may slow down and stop as the green signal nears its end, others may accelerate to pass through the junction, increasing the risk of head-rear vehicle collisions.
Given the circumstances above and the overriding priority of road safety, the TD will continue to closely monitor future technological developments and the practical applications of such devices. Their suitability for use in Hong Kong will be considered with prudence and care.
